Qatar Rail Safeguarding of the Metro, Light Rail Transit and Long Distance Railway Protection Zones Company Management System

Introduction

The national transportation objectives and requirements are prepared in accordance with the Qatar National Development Framework (QNDF). Based on the Qatar National Master Plan (QNMP) railway corridors and station locations are developed in close coordination with the planning authorities Qatar Railways Company became the Permitting Authority for all rail related operations in the State of Qatar with the introduction of Law 10 in 2014. Rail operations include the Metro, Long Distance, and any other rail transport systems. Purpose The introduction of railways in Qatar means that it is necessary to define the protection of these railways. To ensure the protection of the railway the Railway Safeguarding has been introduced. Accordingly (Railway-) Protection Zones have been established, which are defined areas around railway infrastructure, where activities which may affect the railway are closely controlled. The aim is to ensure that developments along the railway corridor do not effect on the ability to build, extend and operate the railways. Under Law 10 of 2014, any person intending to carry out activities in the (Railway-) Protection Zone shall obtain prior permission from Qatar Railways Company before commencement of work on site. Within the Railway Protection Zone Qatar Railways Company is the custodian of the Railway Corridor. Permissions are usually provided in form of No-Objection Certificates (NOC) for the design and construction of the proposed scheme. Scope The scope of this document includes defining the Rail Protection Zone for any railway activity through each phase of the project life cycle: • Planning stage • Construction stage • Operational stage. Intended Audience

This document is intended to be used by:  Municipalities and government agencies  Developers and property owner

 Engineering and design consultants  Contractors

This document shall provide to the user:  Guidelines to create or update their policies, regulations and standards related to new development along railway corridors, in order to create more consistency across the country.  A tool to better understand the safeguarding related to new development along railway corridors, and to more effectively evaluate and provide feedback on development proposals.  Better understanding of the interface between the development sites and the railway in the proximity of railway corridors. Public Transport Network for Qatar GCC Railway - The GCC Railway is planned as a regional integrated interoperable railway supporting the transport needs of the Gulf Cooperation Council both in the form of freight- and passenger-travel. The railway will pass through at least one city within each of the GCC member states linking , Kingdom of , Kingdom of , Qatar, the and . The Rail Network of Qatar has been developed on the basis of a GCC agreement (GCC Railway) and the Public Transport National Network Master Plan for Qatar. In Qatar, in addition, connections have been included to serve the freight & passenger market across the country, planned to be deployed in several phases. Safeguarding Safeguarding is a term for an established part of the planning system that protects large- scale infrastructure projects from conflicting developments. It provides a statutory mechanism by which Local Planning Authorities consult with Qatar Rail on existing and future planning applications which fall within the safeguarded areas. Safeguarding is defined by design and construction requirements, and the estimation of future requirements such as for operation and maintenance. The inclusion of land within the safeguarded zone does not mean that it will be used by the railway project(s). Fundamentally, safeguarding is a precautionary measure to protect the railway from conflicting developments. The width of the safeguarded corridor includes different zones. However the dimensions of the zones vary, where appropriate, to reflect the needs of the railway in that particular location. The safeguarding boundaries will be subject to periodic review as the project design evolves. Boundaries may be amended due to third party stakeholder impact outside of Qatar Rails control.

Railway Protection during Life Cycle Stages

Planning Stage During the planning and design stage Qatar Rail assesses No Objection Certificate (NOC) requests for activities within the Railway Protection Zone. Qatar Rail will review the NOC request in regard to the degree of possible interaction and interference with any railway asset. This process is part of the railway planning procedures within Qatar, and in particular is controlled by the ‘Final Rail Route Approval’ (FRRA) process and the ‘Station Area Planning’ (SAP). If the request is acceptable, an NOC or permit is issued to the third party for a period of 6 months for utility & infrastructure schemes and for a period 1 year for developments with a Parcel Identification Number (PIN). The (Railway-) Protection Zone is defined as the zone within which any third party activities require an NOC from Qatar Rail before commencement.

Construction Stage During the construction of any railway network, Qatar Rail may engage Project Management Consultants (PMCs) and contractors to manage and carry out rail design and installation works. Qatar Rail will coordinate with the PMCs and contractors to assist with the NOC review process. The (Railway-) Protection Zones during the construction stage are the same as those defined for the planning stage. During construction stages the contractor will be responsible for the site area and third parties may be directed to coordinated and agree any interfaces with the Metro designer and/or contractor. Operational Stage Throughout the operational stage, Qatar Rail will be responsible for railway protection, working in conjunction with the Operator/Maintainer. Qatar Rail will continue to review any planned developments within the Railway Protection Zones. In addition, during the operational stage there will be increased emphasis on issues which have the potential to affect safe train operation or the structural integrity of the rail infrastructure. The (Railway-) Protection Zones and Critical/Exclusion Zones during the operational stage may be different from the zone demarcation during planning/design and construction of the railway.

The Overall Approach

Description of Safeguarding Approach The Railway network passes through different environments in Qatar. These environments can differ in terms of topography, and infrastructure and rural surroundings. Qatar Rail has developed standard corridors based on international standards and site conditions. The corridor width will however vary depending on the need of the railway at that particular location and the design stage.

Maintenance and Turnout Sections A wider safeguarded corridor has been allowed at locations along the rail route where multiple tracks are used, routes are separating and merging, and at station and maintenance areas and other related locations. Maintenance sections incorporate sidings used to provide stabling for maintenance trains that are required for operational maintenance work and allow the line to be cleared with limited delay in case of a breakdown. Turnout sections are required to allow for overtaking, stabling and bypassing station platform tracks. Railway Zones

Railway Corridor The Railway Corridor is defined as the land which contains the railway track or tracks and is generally equal to the Railway Protection Zone which comprises:  The tunnel or rail track structure  The exclusion zone  The minimum distance between two adjacent tunnel tubes or railway lines  The minimum dimensions for auxiliary components (ditches, berms, etc.)  Safety buffer

(Railway-) Protection Zone (R-) PZ The (Railway-) Protection Zone is a safety zone in which any third party has to obtain approval (NOC) from Qatar Rail for the safety of the railway. This zone consists of the Critical Zone and a dimension as safety buffer on either side of the Critical Zone.

Critical Zone CZ The Critical Zone is defined as the zone within which normally no third party activities shall be allowed. In exceptional circumstances, activities within this zone may be allowed;  after detailed analysis has been carried out and  Qatar Rail may decide to impose additional controls and restrictions as considered required. Sometimes, the Critical Zone comprises the boundaries of the land acquisition. These boundaries should be kept as straight as possible.

a) Tunnel Section The Critical Zone consists of the tunnel itself, the construction tolerance zone, exclusion zone and alignment adjustment zone.

The tunnel diameter is the longest distance between the opposite outer edges of the tunnel ring (segment) including cement injection grouting zone around the tunnel ring which is also considered as part of tunnel.

For tunnels a construction tolerance zone will be taken into account. The construction tolerance zone is defined as a square with side lengths 1 metre greater than the tunnel diameter.

In addition an alignment adjustment zone (tunnel only) has to be considered. The Alignment Adjustment Zone is the zone around the Exclusion Zone which provides the railway designer with the flexibility to adjust the tunnel alignment horizontally and vertically. The zone underneath the tunnels is defined as infinite to safeguard maximum flexibility in vertical deviation.

Qatar Rail Safeguarding of the Metro, Light Rail Transit and Long Distance Railway Protection Zones Company Management System

b) Elevated / At-Grade Section The Critical Zone consists of the structure itself and the exclusion zone.

Restricted Activities Restricted activities are activities which when carried out in the vicinity of the railway would expose the railway to danger. The restriction applies to all third party activities planned, designed and constructed (intended) within the Protection Zone (RPZ).

Restricted activities could cause injuries and fatalities to railway staff, workers, members of the public and passengers or result in damage to the railway thus disrupting train service.

Excavation Zone The excavation zone is a zone around a rail structure which is usually bigger than the actual structure to be built in order to allow for temporary works. The excavation zone may vary depending on the actual situation on. Site circumstances and conditions may require a wider excavation zone. Also, if site conditions allow it, Qatar Rail will reduce the excavation zone, in order to keep the impact to a minimum.

Exclusion Zone The Exclusion Zone is the zone where no third party structure is allowed. For any planned third party structure intruding into these zone approvals from Qatar Rail must be obtained. Approvals are only provided in exceptional cases. Zone Hierarchy The requirements become more critical as the distance to the railway decreases. The protection zone hierarchy is shown in figure 1.

Qatar Rail Safeguarding of the Metro, Light Rail Transit and Long Distance Railway Protection Zones Company Management System

Vertical Clearances The transport network of the State of Qatar consists of the railway/metro/light rail network which is bound to a fixed track alignment and roads / highways. Since both networks co-exist, crossing structures cannot be avoided. In order to allow for an economic and efficient design Qatar Rail allows for certain reductions in the vertical clearance above the top-of-rail (ToR). The applicability of such reduced clearances is associated with conditions and requirements as stipulated by Qatar Rail. In these cases full review, coordination and agreement with Qatar Rail is required. Track Arrangement The number and distance between tracks can vary depending on the use, purpose, railway furniture (utilities, catenary line, masts, signalling equipment, etc.) and overall cross section. Also track gauge, Dynamic Kinetic Envelope, and other related rail clearance requirements are dictating space requirements. Future upgrades might require the construction of full-width structures and embankments, to cater for additional track(s) and equipment which will be built at a later time. Typical Protection Zones - General The Railway Protection Zones and Critical Zones during the planning/design and construction stage for different structures are shown in the figures as listed below. See Appendix A.

Zone of Influence

Any building or structure has a foundation to transfer load from the structure and traffic above into the ground below. Different foundation types can be used to achieve structural stability and firm bearing. When two foundations are installed close to each, the Interference between the footings has to be assessed. This may be the case due to architectural requirements or the less availability of space for the construction.

The assessment needs to consider amongst others, the soil conditions, the ultimate bearing capacity of each foundation which may change due to the interference effect of the failure surface in the soil. Also (differential) settlement to be reviewed and measures to be taken into account not to damage surrounding structures.

The proposed construction activity may be within the proximity of the rail tunnel, underground station, rail foundations and any related structure which requires study and assessment of any potential effects on the railway.

Typical Protection Zones for Tunnels The following figure shows the relevant zones for Metro and Long Distance tunnels.

Figure 4 Type 1 - Typical Protection Zones for tunnels (Metro / Long Distance)

Typical Protection Zones for At Grade Railway Systems The Qatar Rail projects include at grade railway systems for the Metro and Long Distance Railway schemes. In addition, clearances to structures crossing over/above the railway are required to be maintained to allow safe passage of the railway underneath including all system components and safety clearances. For confined situations, where space is limited (i.e. centre reserve with highway on either side), no structures are allowed within the Critical Zone but normal road construction may be permitted. The protection zones may vary depending on the location specific track arrangement. In cases where there are more than two tracks, maintenance tracks, high embankments, deep cuts and diverging tracks the safeguarded zones will differ from the typical zones shown in this document. The following figures show the relevant zones.

See Appendix B - Typically the (Rail-) Protection Zone is [100 &100] meter from centreline of all tracks combined; total width of Rail Protection Zone is 200 meter. In “open field” locations the rail protection zone and the critical zone will be the same. “Open field” see definitions.

Long Distance Protection Zone Reduction Depending on the situation the protection zone may be reduced from 200 meter to 100 meter and down to 50 meter, with special construction measures and Qatar Rail’s approval (NOC). This reduction has to be assessed on a case by case basis and can be used for plots or other constraining infrastructure conflicting with the railway corridor.
