Some layouts occur so frequently that they have acquired their own names. Probably the commonest of these is the CROSSOVER, in which two turnouts are laid crossing Fig 9.3 (a) to crossing in adjoining tracks to enable trains to change tracks, as in Figure 9.3(a). Fig 9.3 (d) This is one of the commonest layouts and in former days it was often referred to as a “LEAD”. This name led to the use of the term “half lead” to describe a turnout. If two crossovers are laid across one another as in Figure 9.3(b), the layout becomes a Fig 9.3 (b) SCISSORS CROSSOVER. In this layout there are four turnouts and one diamond. Fig 9.3 (e) In a DOUBLE JUNCTION two tracks diverge from a double track through line, as in Figure 9.3(c). This layout consists of two turnouts and one diamond. An OUTSIDE SLIP consists of two turnouts and a diamond, arranged as in Figure 9.3(d) so that in addition to travelling along either of the two straight tracks, trains Fig 9.3 (c) Fig 9.3 (f) can transfer from one to the other. The addition of two more turnouts on the opposite side of the diamond makes it into a DOUBLE OUTSIDE SLIP. In such layouts the Figure 9.3 S&C Configurations commonly in use route from turnout to turnout is called a slip road or track. An INSIDE SLIP serves the same function as the preceding layout but the slip roads are contained within the diamond, thus saving space. The components of a single A crossing enables a wheel travelling along a given rail to pass through the rail of a inside slip, shown in Figure 9.3(e), are a diamond and two pairs of switches without track which crosses its path. Refer now to Figure 9.4(a). This shows two tracks crossings. The addition of two more pairs of switches makes it a double inside slip, crossing one another at right angles. In each of the four corners of this square is a sometimes called a compound or double compound. CROSSING. It will be seen that there are basically four identical L-shaped pieces and four identical short lengths of rail. The gaps between the short lengths of rail and The final example of a layout is the TANDEM, shown in Figure 9.3(f). Here, two the L-shaped pieces are necessary to allow the wheel flanges on one track to turnouts are laid one after the other in series. In the type of tandem shown, the toes of the switches are separated by a distance somewhat greater than the length of the switch rail from toe to heel. If the toes of the switches are placed as close together as possible the layout becomes a threethrow; this type of layout is restricted to sidings where space is very restricted, as gauge variations are unavoidable. Turnouts and diamonds are themselves composed of two elements: • Crossings • Switches This chapter will first describe the parts of crossings, how they are designed, and how they are made. Then turnouts and switches will be dealt with in the same way. The geometrical design of S&C work will be described, starting from the simplest form of turnout and working up towards the more complex layouts. 330a 330b.

A great layout needs good trackwork, so first - a word about trackwork and getting good performance. Choose carefully! DO think about making your own turnouts if you have even moderate skills. It is not as hard as you think, needs only basic skills and tools... and we do our best to make it easy with our top quality gauges, trackwork frets and templates. PLUS we will soon provide a detailed “How to make track” tutorial too. Interested? Then call or email us and we will do our best to help you. No matter what scale you will model in, DO NOT even consider using insulated frogs! Yes, lazy retailers who do not understand what they sell - and modellers who have never done a proper job of laying track so it runs well may well recommend it to you… but do NOT be tempted. No matter which brand makes the turnouts, if you use insulated frogs, you WILL have small locos stalling or also suffer from wider wheels bridging the frog tip and creating momentary shorts that are hard to fix and really are a source of constant frustration. Use more realistic rail sizes please: Usually this will be code 55 in N, or Code 75 and 83 in OO or HO Scale.

  • Appendix J Haddington Branch Line Survey
    Appendix J Haddington Branch Line Survey AllanRail East Lothian Access STAG Physical feasibility of re-opening the Haddington Rail Branch Line Background The reopening of the Haddington Railway branch line from the East Coast Main Line (ECML) at Longniddry to Haddington is one of the options that are required to be considered in the East Lothian Access STAG. This initial report informs the appraisal work of the feasibility of re-opening the railway, some of the issues and problems that would need to be resolved, choices that are available and suggests an order of magnitude cost. Because the rest of the railway is electrified it is assumed that the Haddington branch will also be equipped with standard 25Kv overhead electrification equipment. The report is based on a physical site walk-over on 21 February 2019, carried out by David Prescott of AllanRail who has considerable experience in the initial development of re-opened railways in Scotland including walk-overs on the Stirling – Alloa – Kincardine, Airdrie- Bathgate and Borders Railway routes in the inception and pre-construction stages. This is not an engineering assessment, but an initial view based on observation and experience. The route is considered in the Longniddry to Haddington direction and the report is broken down into key route sections. Connecting to the ECML The ideal connection to the main line has several desirable operating and engineering requirements: · It should be on the Edinburgh side of Longniddry to minimise the occupation of the ECML; · It should provide as

Preface Preface The purpose of a Rail Accident Investigation Branch (RAIB) investigation is to improve railway safety by preventing future railway accidents or by mitigating their consequences. It is not the purpose of such an investigation to establish blame or liability. Accordingly, it is inappropriate that RAIB reports should be used to assign fault or blame, or determine liability, since neither the investigation nor the reporting process has been undertaken for that purpose. The RAIB’s findings are based on its own evaluation of the evidence that was available at the time of the investigation and are intended to explain what happened, and why, in a fair and unbiased manner.

  • How Can Forecast Growth and Partners' Aspirations
    FINAL / OFFICIAL Continuous Modular Strategic Planning How can forecast growth and partners’ aspirations be accommodated in the Trent Junctions Area? Strategic Question April 2019 OFFICIAL Trent Junctions / FINAL A. Foreword As part of the railway industry’s Continuous Modular Strategic Planning (CMSP) approach adopted for the Long Term Planning Process (LTPP) we are pleased to present the response to the Trent Junctions area Strategic Question. By 2043, there will have been significant investment in the railway in the East Midlands, firstly through the Midlands Rail Hub scheme which will deliver new services between the key cities of the East Midlands, and the High Speed 2 East Midlands Hub station between Derby and Nottingham. As these new services are introduced, they need to be integrated into the wider rail network, providing a punctual, reliable and valuable service to passengers. One of the major challenges to the introduction of new services around the East Midlands is the Trent Junctions area. Partners from across the rail industry and government identified this as a priority for a CMSP Strategic Question because of the large number of capacity and feasibility studies which have looked at this area. Each of these studies has worked with varied train service and infrastructure assumptions. This study takes an holistic view of these studies, combining them to identify specific locations which will be capacity constraints in the future. Since the Midland Railway Company built Trent Junctions in the mid-nineteenth century, the layout of this area has evolved to deliver different services as the different flows across the junctions have changed.

Our motivation is to develop a modelling and ver- ification approach accessible to railway engineers: it is vital that they can validate the models and verification conditions, and — in the case of design errors — obtain comprehendable feedback. In this paper we run through a full production cycle on a real double junction case study, supplied by our industrial partner, who contributed at every stage. As our formalization is, by design, near to their way of thinking, they are comfortable with it and trust it. Without putting much effort on optimization for verification, the scale of the models analyzed is comparable with the work of other groups. Keywords: Railway verification, CSPjjB, modelling and analysis, ProB. 1 Introduction Formal verification of railway control software has been identified as one of the “Grand Chal- lenges” of Computer Science [Jac04]. But in respect of this challenge, a question has been asked by the community: “Where do the axioms come from?” [Fia12].
