2 Scope of Work, Methodology and Deliverables
2.1 Scope of Work
In April 2010, a number of additional tasks were undertaken by Arup (refer to Arup, st Technical Financial Proposal, Section 3, dated 31 March 2010), one of which focused on the development of proposals for the siting of the Infrastructure Maintenance Depot (IMD). This report deals with the siting and specification of the Infrastructure Maintenance Depot. The obj ective of t his r eport i s t o pr ovide op erational and e ngineering proposals t o as sist HS2 to identify the best possible location and the master layout of the depot for the London to West Midlands HS2 route. The report identifies a suitable site for the IMD and develops a m aster layout f or the site, including both rail infrastructure and ancillary facilities such as office accommodation, services buildings, s torage an d lay down areas, s taff par king, ap proach r oads and ot her related items. The report makes proposals for a solution which appears to provide the best combination of facilities and location. It does not make conclusive proposals, and is provided to inform and illustrate. I t i s ex pected t hat t he s ite des ign will d evelop o ver t he nex t per iod f ollowing further consideration by HS2 and discussions with Arup, and meetings with relevant stakeholders such as the East West Rail (EWR) project and Waste Recycling Group (WRG).
2.2 Meeting 1
An initial scoping meeting took place in London on 28th April, attended by – HS2 and Arup. The m eeting identified a s et of t asks w hereby Arup was r equired t o r eview t he f ollowing factors relating to the IMD. These are as follows: • Location; • Functional Requirements; • Maintenance Strategy, Size; • Site Issues, Equipment; • Visual Impact including simple visualisations; • Relationship to Calvert Waste Plant; • Geology/Aquifers, settlement, Constructability; • Cost, Programme; • Electricity Supply; • Liaise with construction logistics; and, • Environmental issues and constraints. The deliverables were agreed to be: • Large scale plan of depot layout , interface with HS2 and the National Rail network, and surrounding area; • Horizontal al ignment dr awings of c onnectivity to HS2 and ex isting r ail line ( East- West main line); • Master plan of depot; and, • Report.

2.3 Intermediate instructions
In an intermediate discussion between John Castle (HS2 Senior Route Engineer) and Chris Lees (Arup Project Manager) on 14 th May, a list of possible sites was agreed, which Arup would scope to provide initial comments on suitability and functionality. These plans were prepared and discussed at Meeting 2.
2.4 Meeting 2
A s econd m eeting took place at Arup’s offices on 19 th May. At this m eeting a number of potential s ites were r eviewed and t heir attributes di scussed. T he H S2 t eam pr ovided a n input on the preferences for each site, and after discussion a refined set of objectives were produced. In addition to the above deliverables these comprised of:
• Development of proposals for sites 2.2 and 3.2, and a new option for a single ended set of sidings inside the chord line (site 2.3);
• Extension of the scope to examine any other possible level sites on HS2 up to 10 km north from Calvert; and,
• Review of op tions f or pos sible use of Ministry of D efence ( MOD) Bicester as a n I MD site.

3.1 Context
This s ection di scusses the current rail r outes in the C laydon ar ea, an d summarises proposals f or their development in t he next 10 years. T he p ossible impact of locating an IMD at Claydon is also discussed. The current track layout is shown in the diagram below. Track layouts are accurate but in diagrammatic format.

3.2 Oxford - Bletchley
The East-West Line is the former Oxford to Cambridge, via Bletchley and Bedford, line. The status of the route is as follows:
• Oxford to Bicester Town – single track with no passing loops, used by passenger trains from O xford – Bicester T own, f reight t rains f rom D idcot t o MO D B icester, and freight trains from London and Bristol to the WRG Calvert private siding.
• Bicester Town to Claydon Junction - single track with no passing places. Used by freight trains f rom London a nd B ristol t o the W RG C alvert pr ivate s iding. A t C laydon LN E Junction there is a run round loop where trains bound for Calvert can reverse.
• Claydon London North Eastern (LNE) Junction to Bletchley – the line has been out of use since 1997, though it is officially still operational and only ‘mothballed’. Some track sections are missing and the route is unusable at present.
• Bletchley to Bedford– the line is double tracked and used by a passenger service from Bedford to Bletchley, and occasional freight traffic.
• Bletchley t o Mi lton K eynes – a c hord line gives ac cess t o t he West C oast Ma in Li ne (WCML) heading north to Milton Keynes. This and the run round loop at the current end of the branch were previously used by engineering trains running from the Network Rail Stewartby Local Distribution Centre (LDC) to the WCML.
3.3 Aylesbury – Claydon Line
The Aylesbury to Claydon line is a remnant of the former Great Central Main Line. The line is single tracked and the only connection is a set of loops to serve the WRG Calvert waste

transfer terminal. This terminal is served by trains of containerised domestic refuse from the London and Bristol areas to the site for landfill, and some bulk trains of low grade hazardous waste. Freight traffic runs to the terminal from both Aylesbury and Claydon directions.

Some track doubling will be carried out, and a half hourly Oxford to Marylebone service will be run. TWO powers are currently being applied f or, and t he pr oject i s ex pected t o b e c ompleted by 2013. E vergreen 3 i s a DfT franchise commitment.
3.6 East West Project
East –West R ail ( EWR) proposes to refurbish the Oxford – Bedford (and ul timately Cambridge) r oute, and r estore dou ble t rack on t he O xford t o C laydon s ection. F rom Claydon to Bletchley a new double track formation will be provided on the existing trackbed, and the section on to Bedford will be upgraded. EWR proposes a linespeed of 90 mph. The single l ine from A ylesbury will b e retained b ut u pgraded to 90 m ph. Comprehensive new s ignalling f acilities will be r equired t o provide s ufficient capacity on b oth routes. T he project is intended to be completed by 2017, subject to funding from central government and other sources such as property developers. Once complete the following service pattern is contemplated:
• Hourly Oxford to Milton Keynes;
• Hourly Oxford to Bletchley;
• Hourly fast Oxford to Milton Keynes;
• Hourly freight Oxford to WCML;
• Hourly Milton Keynes to Bedford; and,
• Hourly Aylesbury to Milton Keynes. No n ew s tations are proposed in t he C laydon/Calvert ar ea, with t he ne arest pr oposed station being at Winslow. Provision has been made for one daytime freight train per hour in each direction, but it is not clear how m any ( if any) of t hese p aths would b e available f or us e by HS2 i nfrastructure services. Capacity for freight trains to access the intermediate run round siding at Claydon is bound to be restricted. EWR will have to provide a new run round facility at Claydon, at roughly the point identified for run round loops to serve site 2.3, and there may be synergy between the projects here. It is unclear how EWR proposes to manage construction logistics, a nd whether t here i s s ynergy between t he pr oject and H S2 for t he l ocation of construction and track laying depots. Discussions with EWR would help resolve this.

4 Functional Requirements Both A rup an d H S2 dr ew up ou tline s pecifications of t he F unctional R equirements f or an Infrastructure Mai ntenance D epot. Arup c arried o ut a c omparison of t he t wo d ocuments. There was a large degree of agreement in the requirements specified by both teams, and the results were therefore combined into one master Functional Requirements Specification (FRS). This was debated and agreed at Meeting 2. At t his s tage the FRS is i ntended t o b e a d iscussion doc ument, r ather t han a c onclusive statement of needs , a nd the intention is t hat t his f orms t he bas is of d iscussions an d consultations with stakeholders within HS2 and the wider rail business. The requirements were slightly revised following the meeting, to reflect emerging thinking by the H S2 t eam and t o al so t o incorporate s ite d evelopment t hinking. I n particular t he following changes were made:
• Storage sidings were allowed to be single ended to allow adoption of a more compact site.
• The range of track materials to be stored at the IMD was increased to include drainage, troughing and other materials.
• The r ole of Li ght Maintenance D epots ( one of w hich w ill be located at t he I MD) was clarified to reflect the need for maintenance staff to be based at the IMD site.
The c urrent F unctional R equirements S pecification ( FRS) i s i ncluded i n t his d ocument as Appendix A. The FRS has been used in the consideration of the suitability of each site to ensure that the selection process reflects the need to eliminate sites which are functionally unsuitable before consideration of a short list on the grounds of environmental, engineering and financial merit.

5 Site Location Options
5.1 Introduction
To determine suitable site locations, Arup drew up a depot footprint and i dentified suitable areas where the footprint could be accommodated. The basic criteria for the site footprint (taken from the Functional Requirements Specification) were as follows:
• Level site.
• Straight site.
• Site length of approximately 1 km.
• Capability to connect with both HS2 and the EWR.
• Minimisation of environmental impact by avoiding:
o Immediate proximity to built up areas; o Use of flood plain; and, o Areas of high visual impact. A range of s uitable s ites was identified, allocated b y each qu adrant of t he two r ail r outes (HS2/Aylesbury – Calvert line (MCJ1) and The East West Oxford – Bletchley line (OXD) as shown below:
• Quadrant 1 North West
• Quadrant 2 North East
• Quadrant 3 South East
• Quadrant 4 South West

The s ites were then r eviewed in detail for s uitability against t he r equirements of t he F RS and for the means of linkage with both HS2 and the national rail network. Conclusions were drawn for each site as a result of this exercise. Sites are defined by using the following nomenclature: the first number refers to the quadrant they are located in, and the second number is the individual site identifier.

Connections to HS2 It is not possible to build a West to South chord line to access HS2. It is also not possible to build a West to North chord to access HS2 without going very near to the village of Twyford and going through Portway Farm. The only way to access HS2 is to use a run round loop to the E ast of H S2 ( shared with t he waste t rains t o C alvert) t o ac cess i t f rom t he opp osite direction.

The EWR line rises at approximately 1 in 209 in this area, which means that significant earthworks would be required to create a level site. In addition, this would mean that the viable site would be

near t o the existing C laydon London N orth E astern (LNE) Junction. Although t he s ite is below the village of Steeple Claydon it would be within 500 metres of it. The Eastern end of the site lies on flood plain.
Connections to HS2 There is already a chord line running from East to South that accesses the HS2 route which is used by the waste train running from the Bristol area to Calvert. It is possible to build an East to North chord to access HS2.

Description The site lies on the track of an E ast to North chord line running from the EWR line to the HS2 North section heading towards Birmingham. The site would have to be curved to follow the route of the chord. The level of HS2 in this area is not finalised, but it is intended that it will run at level and the EWR line will be raised to run over it. This assumption means that the s ite c ould b e l evel with r elatively m inor ear thworks. Land t ake w ould be c onsiderable though, using relatively open farmland. T he s ite would b e c lose t o t wo relatively isolated houses, but not near significant habitation and not within the view of nearby villages.
Connections to HS2 The site lies on the chord line to HS2. Access to the site from the Oxford direction would be via a run round also required for waste trains from Bristol to Calvert. Access to HS2 South would be via run round loops alongside HS2 opposite the village of Twyford.

Description In agreeing that this could be a possible location, the requirement for all storage sidings to be double ended was relaxed. The site lies to the i mmediate East of HS2 an d within the East to North chord line, bounded to the South by the EWR line, to the West by HS2, and to the N orth East b y the c hord l ine. The l evel of H S2 i n t his ar ea is no t f inalised, but it is intended t hat it will run at level an d t he EWR line will b e raised over it. T his a ssumption means that the site could be level with relatively minor earthworks, though the former Great Central Main Line embankment would need to be removed. Land take would be relatively modest, and would maximise use of land already sterilised by the construction of the chord line. The site could be accessed from the Northern section of the existing unclassified “Thame R oad”, w hich in a ny c ase will r equire t o b e di verted because it crosses the EWR line at almost exactly the point where HS2 will intersect it. The s ite is n ot adjacent t o a ny properties. I t a ppears t hat a lmost al l the s ite c ould be constructed i n one field running in a n L s hape f rom C laydon J unction t o t he HS2 r oute, though land o wnership has not been r esearched. I n t he South W est corner of t he s ite between the East West “Thame Road” overbridge and the GC embankment there is a gas Pressure R educing Station on t he nat ional gas n etwork, ow ned b y S cotia N etworks Lt d. There does not ap pear t o be a di fficulty in d esigning a s ite layout t hat pr eserves this. However t he location of t he as sociated gas p ipelines has no t yet been as certained in a services search a nd this may pr esent a pr oject r isk i f t he pipeline is f ound t o r estrict s ite layout options or operations. One public footpath runs across the site, which will require closure or diversion.
Connections to HS2 Access to HS2 would be via the run round loop also required for waste trains from Bristol to Calvert, which would also act as headshunt for the site. A chord line would be constructed to the HS2 north, and trains to HS2 south could either use this chord and run round at the loops near Twyford village, or could use the existing east to south chord and access HS2 opposite the waste terminal.

There is a 5 metre difference in line height from one end of the site to the other, which means that a level site could only be created with considerable earthworks. It is understood that the site is owned by Waste Recycling Group (WRG). There is no road access t o t his ar ea, t hough t here is a pr oposal by WRG t o c onstruct an ac cess on t he former Grendon Underwood – Ashendon Junction line trackbed. The site is bounded to the North by Sheephouse Wood, which is a Site of Special Scientific Interest (SSSI). The site is not overlooked by any significant residential areas.
Connections to HS2 The site is alongside the HS2 route, and accessed from the EWR line via the existing chord line. A West to South chord is not possible because of a nature reserve and lakes which lie on the route. The only way to access HS2 from the Oxford direction is to use a run round loop to the East of HS2 (shared with the WRG waste trains to Calvert). If the East West proposals ar e i mplemented, i t is un derstood t hat t here i s likely to b e a n h ourly s ervice i n each direction along the existing single line.

5.6 Sites on HS2 (north)
5.6.1 Site 4.0 Mixbury At the m eeting on 19th May HS2 asked Arup to widen its consideration of sites to include any l evel site on the HS2 alignment North of Calvert and within 10 km of the junction with the EWR line. A search on the proposed HS2 route revealed only one potential site which met the required attributes of length and level at Mixbury, just on the 10 km boundary. The site lies on the West of the HS2 route, to the South West of Mixbury village. While the HS2 formation is level at this point the adjacent land rises to the North West, which means that substantial e arthworks w ould be r equired. T he land i s in agr icultural us e a nd i s directly overlooked only by Mixbury Lodge. A public footpath runs across the site.

5.6.2 Connections to HS2 The site is alongside the HS2 route, and would have to be reached by construction of a new 10 km single line from Claydon, which would need to cross the HS2 formation at some point by either an overbridge or underbridge, depending on the vertical alignment. Access from the EWR line would be via a new East to North chord line. Access from the Oxford direction would be via a run round loop to the East of HS2 (shared with the waste trains to Calvert).

6 Cost Estimates We hav e c arried out a n i nitial hi gh level as sessment of t he potential c osts i nvolved in creating the depot. This is be based on compilation of an outline bill of quantities for each of the sites, using standard assumptions on track layout and required facilities, but customised for each site to reflect specific attributes. The bill of quantities has been priced using unit costs based on Arup rate and experiences on recent similar projects with similar attributes. The costs should be treated as indicative, and demonstrating in relative terms the respective costs of each of the options considered. The summary of the cost estimates is shown in the table below.

The s ites w ere r eviewed t o i dentify whether t heir s pecific at tributes ag ainst a list of k ey requirements as set out in the Functional Requirements Specification, and other key requirements which have been identified during project development. Each site was scored in a range of 1 (poor) to 3 (good) for each of the requirements, and then the scores were totalled. Although a relatively crude measure, this provides an easily understood guide to the relative merits of the various sites. The matrix should therefore be read as providing a guide rather than as being a definitive sift process. The evaluation for each site is shown plotted on the matrix below:

7 Conclusion Following assessment of the sites, we have drawn up conclusions of the suitability of each location, i ncluding t he r esults of the m atrix assessment a bove, an d other m ore qualitative factors w hich ap ply s pecifically to c ertain s ites. T he c onclusions of t his exercise ar e summarised below.
7.1.1 Site 1.1 Twyford Lodge The site would be very visible from the village of Twyford and relatively inaccessible from HS2. A new west to north chord line would be relatively intrusive because of the angle of the lines in this area. It is recommended that this site option is not developed.
7.1.2 Site 2.1 Pond Road The topography of the land in this area would make connections difficult without substantial earthworks. The s ite i s c onsidered t o be t oo c lose t o t he v illage of S teeple C laydon an d interferes with the flood plain. It would also require Pond Lane to be diverted or closed. It is recommended that this site option is not developed.
7.1.3 Site 2.2 Claydon Junction The site would be viable, but requires relatively large agricultural land take and is closer to Steeple Claydon than option 2.3. Given that option 2.3 appears to offer reduced land take, a more compact site and is further from neighbouring residential properties it is recommended that this site option is not developed.
7.1.4 Site 2.3 Thame Road It i s r ecommended t hat t his site is de veloped i n d etail, as i t of fers t he bes t opt ion of minimised land take and minimised environmental impact. However in view of the potential risk to site use posed by the gas pipeline, other sites should be kept under review in case significant issues are identified.
7.1.5 Site 3.1 Greatmoor While it would be technically possible to construct an IMD on this site it would require major earthworks to create a level site. The site is environmentally sensitive, with an SSSI immediately t o t he N orth. There i s al so n o r oad access t o t his s ite. It is t herefore not recommended that this site should be developed.
7.1.6 Site 3.2 Great Pond It is technically possible to construct an IMD on this site, though it is close to Calvert village. The s ite w ould be c omplicated b y t he presence of t he r elocated WRG w aste t ransfer terminal whose r oad access r equirements pot entially c omplicate t he s ite layout. F or t his reason it i s r ecommended t hat the s ite be c onsidered f urther, but not as a d evelopment priority.
7.1.7 Site 4.0 Mixbury It is technically possible to construct an IMD on this site, but the length of new branch line required in p arallel t o t he H S2 f ormation would only be j ustified i f t he s ite c hosen was substantially m ore suitable than o thers. T his is not t he c ase, as s ite levels would require major alteration, while the site itself is in a prime rural setting. It is not recommended that this option is developed.
7.1.8 Overall Conclusion The overall conclusion of the exercise is that the site which best meets the criteria laid down in the Functional Requirements Specification is site 2.3 – Thame Road. Although of all the options, this alone requires engineering train storage to be in single ended sidings (therefore requires increased s hunting m oves,) the s ite h as the advantage of remoteness f rom local communities, and is contained within the overall rail footprint.

Site 3.2 – Great Pond also appears to have some suitable attributes, but is compromised by the WRG discharge terminal and proximity to Calvert village, and therefore should be only examined further if Thame Road appears to have major problems.

8.2 Specific site details
The site has the following features:
• On the assumption that the Thame Road is diverted or closed, the former road formation is used as an access road to the IMD.
• A concept road diversion option is shown, though other work packages are dealing with this.
• A new East to North chord line is constructed to give access to HS2.
• To minimise the HS2 main line connection S&C it is intended that this chord is the only access t o H S2, and t hat t he East t o South c hord is r etained as n ow purely as a n access to the Aylesbury route and waste terminal, though HS2 connections c ould be included without major impact.
• Three run r ound s idings ( all s ignalled f or n ormal s peed ( 30 m ph) en try and e xit) ar e created at t he E ast e nd of t he s ite, f or bot h HS2 engineering t rains and f or t rains accessing the Calvert waste site and Aylesbury line.
• The s idings will be in c utting at l ower level t han t he s urrounding f ields, and w ill be screened by this level difference from Steeple Claydon village.
• An additional loop is c reated a longside H S2 at T wyford t o pr ovide r oute ac cess for engineering trains.
• The chord line and run round sidings are overhead wired, but not the depot itself.
• The chord line, run round sidings and depot are all constructed to UIC GC gauge.
• The chord line forms the railway boundary and all sidings are contained within it.
• Six single ended engineering train storage sidings are created inside the depot.
• A 200 m etre x 40 m etre equipment storage and laydown s ite is provided in the depot and handling will be by 2 gantry cranes spanning the storage area.
• Where feasible overhead lighting will be provided by portals over the tracks to minimise light spillage outside the site.
• The run round sidings will be lit at low level by walkway lights to minimise visual impact.
• Locomotive and yellow p lant s tabling s idings, a m aintenance de pot an d f uelling point, and wagon cripple sidings are all provided in line with the requirements of the FRS.
• Access to the depot is via a barrier controlled level crossing, but the office buildings and car par king ar e s ituated o utside t he r ail b oundary t o minimise movements ac ross t he crossing.
• The rail site will be a high security site with access controlled by gate (incorporating the level crossing). The general administration offices and car parking will be outside this high security area to ensure that only authorised personnel enter it.
• Almost all the site footprint appears to be within one common field boundary, minimising land take and site acquisition.
• The ex isting gas f eeder s tation is s afeguarded and r etained on i ts c urrent f ootprint.

8.3 Site operation
The schematic track layout is shown below.
Figure 17 Concept Depot Schematic It i s i ntended t hat t rains o r r ailborne pl ant ar riving at t he I MD will r un into t he run r ound sidings. Where appropriate, trains could be taken from here direct to HS2. Other trains will be s hunted i nto t he storage s idings to b e he ld ready to g o on to possessions l ater. T rains with materials for the storage area (S&C components, sleepers etc.) will be shunted into the storage yard f or unl oading. I t i s e nvisaged t hat t he de pot will r equire one s hunting locomotive to perform these functions. Yellow plant, ‘thunderbird’ locomotives and other HS2 on track equipment will be maintained and fuelled at the maintenance depot in the North corner of the site, and storage sidings are also provided to stable locomotives while waiting for duty at the neck of the yard. Covered m aterials s tores w ill a lso be within t he r ail ar ea. T he c hord line and ot her r ail routes ( EWR and H S2) will pr ovide nat ural s ecurity, but t he r ail s ite will b e f enced with security fencing, and access will be strictly controlled. The only road access will be via a level crossing. Other site activities (offices, car parking, non essential stores and the Light Maintenance D epot) will b e l ocated out side t his s ecurity area on land t o t he N orth of t he site. Trains bei ng pr epared to g o ont o pos session s ites o n H S2 will be f ormed on t he s torage sidings, ei ther f rom i ncoming t rains or f rom wagons l oaded i n t he s torage area w ithin t he depot. Trains will be pulled out into the run round sidings and taken down to Twyford loop

ready for despatch onto HS2. It is envisaged that propelling movements will be minimised, and that in normal service only trains being shunted into the depot will be propelled. It is envisaged that t he m ajority of possession t rains o n H S2 will be ‘ top an d t ailed’, which minimises the number of run round moves which are required at the IMD or at Twyford.
8.4 West end connections
A sub option of the depot design has been examined, to provide connections between the stabling sidings at the Western buffer stop end, to allow locomotives to run round incoming trains. Connection to the EWR line is not possible at this point, due to the line being carried over HS2 on an overbridge. The location of the headshunt is constrained by the need to avoid the Pressure Reducing Station. The connections for this sub option shown in the diagram, below.
Figure 18 West end connection sub option
The effect of the sub option is to reduce the length of the stabling sidings, as demonstrated in the table below: Usable standage on siding
Single Ended Option Double Ended Option Siding No. 01 775m 537m Siding No. 02 775m 572m Siding No. 03 775m 678m Siding No. 04 775m 678m Siding No. 05 775m 607m Siding No. 06 775m 537m
Figure 19 Comparison of siding lengths: single and double ended
There is limited opportunity to move the yard neck eastwards, because of the tie-in with the chord line and the EWR line. The trade off between maximising the length of storage and increasing o perational f lexibility i s t herefore c lear. Our c onclusion i s t hat the add itional operational functionality offered by this sub option is outweighed by the loss of siding length, and therefore the run round option should not be adopted.

9 Calvert Waste Plant
9.1 Rail Access
This report has not reviewed, in detail, the facilities to be provided for WRG at a relocated Calvert terminal site. It is understood that this will be on the east of the Aylesbury – Claydon line parallel to the existing sidings and near the footprint of site 3.2. It is proposed that the existing sharply curved chord line from Claydon London North Eastern (LNE) Junction will be retained in its current location to minimise environmental impact, and that HS2 formation will be adjusted to provide space for this. The proposed depot location means that the new shallower curved east to north chord can be used for HS2 access, and it is proposed that no use is made of the existing chord, which will only carry Aylesbury - Milton Keynes passenger trains and freight services. Therefore no c onnections h ave b een pr oposed b etween t he Network R ail line and H S2 at C alvert, though this could be provided if desired. In concept, we believe that the waste depot will require two sidings at least 800 metres in length (to provide movement of the train under a static gantry s ite as at pr esent) or 2 x 400 m etre s idings w ith f ull Rail M ounted G antry (RMG) access to the length of the train. Road access to the site will be via a new overbridge to a new circulating area on the east side of the terminal, which is one of the reasons why site 3.2 is not considered suitable for the IMG. Drawing n umber HS2-ARP-07-DR-RW-00011 Issue 1.0 s hows a n i ndicative layout for the WRG, shown on the following page.

9.2 Heat and power generation
The Calvert WRG plant already runs a local power station, fed by methane generated from the landfill area. The landfill will continue to generate methane through the life of the IMD project, and it would appear appropriate to consider using this as a source of fuel for heat and po wer generation purposes, possibly though a small combined heat and power plant, located alongside the IMD. This would potentially allow the IMD to become independent of grid power and gas supplies and would be an a ppropriate ex ploitation of an av ailable c arbon neutral e nergy s ource. Further development of this option in conjunction with WRG would be appropriate.

10 Use of site as a potential construction depot As par t of t his pr oject, discussions h ave b een h eld with t he Arup team r eviewing construction logistics, and options for supplying track materials to HS2. In principle the IMD could provide all or part of this function, though the site is probably too small to handle all the trains required for the two year construction phase. There appear to be two options to supplement capacity.
10.1 Additional land take
It would be possible to provide additional sidings on a short term basis, with restoration of the a dditional site after construction ha d been c ompeted (as happened on the H S1 Beechbrook Farm depot). This would be possible, and such sidings could be to the north of the c hord line on a djacent agr icultural l and. S ome of t he ot her s ites c onsidered i n t his report (and specifically site 3.2) may also be suitable for temporary use.
10.2 Use of other supplementary depots
There are two other sites which are located on the East-West route, and which may have capacity to act as secondary materials supply depots. Neither of these sites could support GC gauge traffic, and their remoteness from the HS2 connections and route access limitations may restrict their usefulness. However they both have the capability of providing the required additional capacity for a short period at minimal capital cost and environmental impact. The MOD site at Bicester is described below, and may have the capability to handle trains for HS2 track lying, though access to the site may be difficult. Network Rail established a site to supply West Coast Route Modernisation (WCRM) requirements at the WRG Stewartby terminal, near Bedford on the EWR line (some 17 miles away). The depot performed the role of a classic Local Distribution Centre (LDC), and had ballast stockpiling and spoil disposal facilities, as well as engineering train storage. There were however problems with operating long (600 metres+) trains because of an automatic half barrier crossing to the east of the site. The terminal is now out of use following the completion of WCRM, and could therefore be adapted for use as a secondary stocking option for HS2 track laying. Because of the distance from the HS2 route this depot has not been evaluated for suitability as an IMD.

High Speed Two (HS2) High Speed 2 Infrastructure Maintenance Depot (IMD)
11 Bicester MOD Depot As part of this review, Arup suggested and HS2 agreed that consideration should be given to the possibility of use of land at the MOD depot at Bicester to perform the functions of an IMD. No discussions have been held with MOD. The Bicester depot is a massive complex which controls most of the stores for the British Army. It is administered by the Defence Storage and Distribution Agency (DSDA), and the rail operation is managed by DSDA Rail and Container Services (DRCS). There are over 30 m iles of track on the 1,500 acre s ite which dispatches traffic b y rail o ver a connection with EWR line a t B icester T own s tation. D RCS owns its o wn l ocomotive f leet and r ail operational personnel. The rail connection and exchange sidings face towards Oxford. DB Schenker has a contract with DSDA to move equipment around the country and through the Channel Tunnel, and operates at least one train per day between Didcot and Bicester. The maximum t rain l ength t hat c urrently c an be ac commodated i nto t he s ite i s approximately 500 metres, though this could be increased with track alterations MOD has been seeking to open the site to commercial use (initially in the distribution sector) which would b e c ompatible with t he c urrent s ite us es. A n o pen day was h eld in 2 009 to canvas p ossible private s ector s upport, though to date no f irm plans hav e em erged. T he site has the benefits of high security, available development land with good rail access and limited planning restrictions, and very good road access to the A41 and M40. However the site is 8 miles from Claydon Junction, and is only cleared to Network Rail W8 gauge ( though t here ar e i ndications t hat D fT may c onsider f unding an i ncrease t o W10 gauge for 9’6” containers as part of the EWR project). There are 6 overbridges on the route which m ay limit t he options f or gr eater ga uge c learance ( one of t hese o verbridges i s t he Chiltern L ine Princes R isborough – Aynho J unction route) t o per mit t he pas sage of G C gauge v ehicles. T he c onnections at Bicester f ace t he w rong d irection, while i n f uture t he EWR and C hiltern Bicester – Oxford s ervice pr oposals m ay limit ac cess opt ions bet ween Bicester and Claydon. For this reason it appears unlikely that a site at Bicester could fulfil the function of an IMD and provide strategic access to HS2 on a daily basis, because of its distance from the route. There c ould h owever b e considerable m erit i n c onsidering locating additional temporary facilities here for the track laying phase of the project, and it would be worth conducting at least a n i nitial c onversation w ith D SDA t o u nderstand what pot ential f acilities c ould b e offered.

Appendix A Functional Requirements Specifications
High Speed Two (HS2) High Speed 2 Infrastructure Maintenance Depot (IMD)
A1 Introduction This F unctional R equirements S pecification s ets o ut t he k ey r equirements f or an HS2 Infrastructure maintenance\depot (IMD). It is the result of discussion between the HS2 and Arup teams. Any design for an IMD must confirm to the requirements of this specification. This document is intended at this stage to be a discussion document, rather than a conclusive statement of needs, and the intention is that this forms the basis of discussions and consultations with stakeholders within HS2 and the wider rail business.
A1.1 Purpose
There will be three light maintenance depots on HS1, where track and infrastructure maintenance g angs will b e l ocated, and t ravel t o worksite b y r oad t ransport. S tocks o f consumable spares will be k ept on site. One of these three depots will be in the London area, one near Birmingham, and the third will be located at the IMD. In the case of major infrastructure work, involving heavy maintenance and renewals, and rail delivery of r eplacement t rack materials will b e s upplied f rom a c entral I nfrastructure Maintenance Depot (IMD). The prime functions of the IMD are:
• Provide a base from which all rail based infrastructure maintenance activities are resourced a nd m aterials s upplied f or t he whole of t he s outhern t runk s ection o f H S2 (Euston – Birmingham inclusive).
• A c entral s upply p oint f or all e ngineering ( track & O LE) m aterial t hat r equires t o be delivered to site by rail plus strategic materials stocks
• A fuelling, servicing and stabling facility for:
o HS2 rescue and recovery locomotives
o HS2 on track plant (including GC gauge vehicles not able to travel on the National Rail network)
A1.2 Assumptions
This document makes the following assumptions:
• Standard track materials common across the high speed and classic rail networks will be supplied by Network Rail from their own Local Distribution Centre (LDC) and transferred to HS2 via the IMD, which will act as the storage and interface point. Track components s pecific t o HS2 will be s tored at t he I MD, which will ac t as t he s trategic supply point for the line.
• Excluding yellow plant moves, the maximum number of possessions to be supplied from the IMD is 2 on any working night, and the maximum number of possession train to be supplied onto HS2 is 4 on any working night.
• Track materials s upplied by t he I MD will b e l imited principally to b allast, s poil, r ail, sleepers, S &C, an d O LE ( masts and wiring). I t i s a ssumed t hat m aterials f or pur ely road b ased m aintenance operations would be h eld at t he L ight Ma intenance depots, and not normally be handled by the IMD (except for those items held by the local depot).
• Except where specifically stated in this document all materials wagons used to supply HS2 will be b uilt t o a g auge c ompatible with t heir m ovement on t he National R ail network (maximum Network Rail W8 gauge).
• Ballasted t rack w ill be t he us ual s pecification f or ope n a ir s ections.
Page A1
High Speed Two (HS2) High Speed 2 Infrastructure Maintenance Depot (IMD)
A1.3 Ballast
The ballast for HS2 will conform to the normal UK Network Rail track ballast specification. Ballast will be supplied by Network Rail, either in standard NR/HS2 ballast wagons (hoppers or side tippers) or in High Output Ballast Cleaners. Rolling Stock would probably be owned by a 3 rd party. A ll t rack bal last will be loaded at N etwork R ail s ites, and t here w ill b e no ballast stockpiling at the IMD. The following requirements are identified for track ballast: • The minimum ballast stabling siding length is 400m. At least one siding must be 775 metres in length to allow for storage of an HOBC. • The HOBC will be serviced and restocked at another site and not at the IMD. • The nu mber of bal last s tabling s idings pr ovided m ust be equa l t o t he m aximum number of ballast trains planned to be supplied to all sites on HS2 on one working night, plus 50% for contingency. • Passive provision will be made for a temporary ballast stock pile of 10,000 tonnes of ballast.
A1.4 Rail
HS2 will be laid with UIC 60 specification rail. Rail will be supplied by Network Rail, normally in 216 m etre s trings on L ong Welded R ail ( LWR) s ets or i n s ingle 20 m etre length on conventional wagons. Rolling Stock would probably be owned by a 3rd party. All rail will be loaded at manufacturing p oints (Corus S cunthorpe or NR E astleigh pl ant) and w ill not be unloaded at the IMD. The wagons used to bring materials from the National Rail; network will be used to drop rail on the HS2 trackbed. Where appropriate scrap rail will be reloaded to these wagons and returned to Network Rail for disposal or reuse. The Track Renewal Train (TRT) does not form part of this section (see sleepers below). The following requirements are identified for handling rail: • The minimum rail stabling siding length is 400m. • One line will be provided for stabling rail wagons (LWR sets or individual wagons).
A1.5 Spoil
Spoil ( used bal last) will b e br ought f rom pos session s ite t o t he I MD, a nd h anded o n t o Network Rail for disposal at an LDC. Rolling Stock would be owned by a 3rd party. Spoil will not constitute hazardous waste. No spoil will be unloaded or handled at the IMD The following requirements are identified for handling rail: • The minimum ballast stabling siding length is 400m. At least one siding must be 775 metres in length to allow for storage of an HOBC.(see section A1.4 ‘ballast’ above). • the number of spoil wagon stabling sidings provided must be equal to the maximum number of s poil t rains p lanned t o be s upplied t o a ll s ites on HS2 on one w orking night, plus 50% for contingency.
A1.6 Sleepers
Sleepers specified on HS2 will be monoblock or twin block concrete bearers with a maximum w idth of 2, 500 m m. S leepers w ill be s upplied f rom t he N ational R ail ne twork, either on 20 metre wagons (Salmons) or as part of the Track Renewal Train (TRT), where scrap sleepers are recovered from the trackbed in a possession they will return to the IMD on the wagons and will be sent on to a Network Rail LDC for recycling. Sleepers will not be stored on site at the IMD. The following requirements are identified for handling sleepers:
Page A3
High Speed Two (HS2) High Speed 2 Infrastructure Maintenance Depot (IMD)
• The minimum sleeper stabling siding length is 400m. • At least one siding must be 775 metres in length to allow for storage of the Track Renewal Train (TRT). • The TRT will be serviced and restocked at another site and not at the IMD.
A1.7 Switches & Crossings (S&C)
It is assumed that S&C will be specific to HS2 and will not be comparable to Network Rail units. C omponents ( switches, c rossings, be arers, p oint m otors, s tock r ails et c.) w ill be stored at the IMD. The IMD will also act as an initial build up area for new S&C units, and transportation to site may be carried out by rail (using GC gauge sleeper carriers along the pattern of similar units being introduced by Network Rail. The following requirements are identified for handling S&C: • New build up area required for S& C units – 150m x 20m. • At least one dead ended siding required with a usable length of at least 200 metres, and access by crane or forklift from both sides of the track. • build up area to have rail access for loading possession wagons. • build up area to have road access for material deliveries. • Component stock area required. • stock area to have rail access for loading possession wagons. • Stock area to have road access for material deliveries. • S&C handling to be by overhead crane (2 heads).
A1.8 OLE
It i s as sumed t hat O LE m aterials will b e s pecific t o HS2 and will n ot b e c omparable t o Network Rail equipment. Components (masts, insulators, registration arms, droppers, catenary wire, c ontact wire etc.) will be s tored at the IMD. T ransportation to s ite may b e carried out by rail (using a specific wiring train) on rail or road/rail equipment, or by road. The following requirements are identified for handling OLE materials: • Component stock area required. • stock area to have rail access for loading possession wagons. • Stock area to have road access for material deliveries. • stock area to have road access for road or road/rail vehicles. • At least one dead ended siding required with a usable length of at least 200 metres, and access by crane or forklift from both sides of the track. • handling to be by forklift truck.
A1.9 Miscellaneous
In addition to the above items, the IMD will also stock standard components for the following systems:
• Track drainage.
• Cable troughing.
• Consumables for track treatment such as de icing fluid, sandite etc.

High Speed Two (HS2) High Speed 2 Infrastructure Maintenance Depot (IMD)
A1.10 Fuelling and servicing
On track plant and rescue locomotives will require fuelling, servicing and light maintenance facilities. It is assumed that heavy maintenance (including tyre turning) will be undertaken elsewhere, but i t i s possible t hat G C gauge equipment will not be a ble t o ac cess ot her depots off the network, and road movement may have to be considered. The following requirements are identified for fuelling and servicing:
• Fuelling facilities for two locomotives or on track vehicles at a time.
• Fuel storage tanks of at least 100,000 litres capacity.
• Full fuel spill recovery facilities to be provided.
• Gas oil to be delivered by road.
• Fuelling siding to be double ended and at least 100 metres length.
• servicing shed to be provided with:
o Single road. o Covered shed with lighting, heating and closable end doors.
o Fitted with fume extraction equipment.
o Provided with under floor pit. A1.11 Crippled wagon facilities
The IMD will be provided with a separate siding where crippled or defective wagons can be repaired and returned to use or moved off site. The following requirements are identified for cripple facilities:
• One dead e nded s iding of at l east 10 0 m etres l ength with t he m eans t o isolate t he points to prevent unauthorised shunt moves into the siding.
• Lighting.
• Under floor inspection pit.
• Road access f or a heav y lift ( 45 t onnes) c rane or l ow l oader t o r emove wagons f rom site.
• Full concrete apron capable of 25 tonne point loads for wagon jacks.
A2 General Requirements The following requirements have been identified for the IMD:
A2.1 General
• The IMD will be located approximately m idway along the HS2 route with the objective that engineering pos session t rains c an r each a ny worksite al ong t he r oute within o ne hour (assuming 100 kph running).
• The I MD will be op erational and ac cessible by r ail at a ll t imes. C apable of 2 4hours operation 7 days per week.
• The site will be lit throughout, but mindful of avoiding energy waste and light pollution to the vicinity of the area.
