4 June 2018GB Requirements for Platform Height, Platform Offset and Platform WidthPage 4 of 19 RSSBU ncontrolled when printed Supersedes parts , and 7 of GIRT7016 Iss 5 with effect from 01/09/2018 Part 1 Purpose and document sets out Great Britain (GB) Requirements in scope of NationalTechnical Rules (NTRs) for Platform height, Platform offset and Platform Requirements of this document are based on the following document sets out NTRs for the GB mainline railway. Compliance with NTRs isrequired under the Railways Interoperability Regulations 2011 (as amended). NTRs in this document are used for the following purposes:a) To fill identified open points in Technical Specifications for Interoperability (TSIs).

5 B) To support UK specific cases in reproduces the Requirements set out in this document together withother applicable GB Requirements concerning the interface between stationplatforms, trains, track and buffer of this national rules relating to relevant TSI parameters have been identified togetherwith the relevant clause from the document sets out a series of Requirements that are sequentially numbered. Thisdocument also sets out the rationale for the requirement, explaining why therequirement is needed and its purpose and, where relevant, guidance to support therequirement. The rationale and the guidance are prefixed by the letter G.

6 Subjects do not have specific Requirements but the subject is addressed throughguidance only and, where this is the case, it is distinguished under a heading of Guidance and is prefixed by the letter G .Related Requirements in other following Railway Group Standards contain Requirements that are relevant to thescope of this document: GIRT7073 sets out the Requirements for positioning infrastructure andmaintaining the position of track relative to infrastructure to achieve gaugecompatibility with rolling stock. GMRT2173 sets out the methods of determining the swept envelope of railvehicles. It sets out specific gauge Requirements for the lower sector and specificitems of equipment and sets out minimum Requirements for the recording ofvehicle gauging data.

7 GLRT1210 defines the Requirements for the AC energy subsystem and theinterfaces to rolling stock operating over the AC electrified Requirements for Platform Height, Platform Offset and Platform WidthRailway Group StandardGIRT7020 Issue: OneDate: June 2018 RSSBPage 5 of 19 Uncontrolled when printed Supersedes parts , and 7 of GIRT7016 Iss 5 with effect from 01/09/2018 GLRT1212 sets out the Requirements for the DC conductor rail energy subsystemand the interfaces to rolling stock operating over the DC electrified following Rail Industry Standards and other documents support this RGS: RIS-7016-INS sets out Requirements for the design and maintenance of stationplatforms for their safe interface with trains, track and buffer stops.

8 RIS-8060-CCS sets out the minimum engineering Requirements for the facilitiesused in dispatching trains from platforms. RIS-8270-RST sets out Requirements and responsibilities for the assessment oftechnical compatibility at route level for vehicles and infrastructure. RIS-2747-RST sets out GB Requirements for exterior doors and selective dooroperation (SDO) and content of this document was approved by Infrastructure Standards Committeeon 07 March document was authorised by RSSB on 27 April Group StandardGIRT7020 Issue: OneDate: June 2018GB Requirements for Platform Height, Platform Offset and Platform WidthPage 6 of 19 RSSBU ncontrolled when printed Supersedes parts , and 7 of GIRT7016 Iss 5 with effect from 01/09/2018 Part 2 Requirements for Platform Height, Platform Offset andPlatform for height of new platforms and alterations (as defined) to existing platforms, the designheight at the edge of the Platform measured perpendicular to the plane of the railsshall be 915 mm (within a tolerance of +0 mm, -15 mm)

9 , except for platforms wheredefined legacy rolling stock is permitted to new platforms and alterations (as defined) to existing platforms where definedlegacy rolling stock is permitted to operate, the design height at the edge of theplatform measured perpendicular to the plane of the rails shall be 915 mm (within atolerance of +0 mm, -25 mm). additional +10 mm tolerance is permitted when a new Platform or platformextension is constructed. Where this +10 mm is used, then the related values for thelower sector vertical clearance (given in GIRT7073) shall be reduced by 10 sets out the Requirements for clearances at station platforms which takeinto account the additional +10 mm tolerance.

10 The tolerances are illustrated in Figure a new Platform or an alteration (as defined) to an existing Platform abuts anexisting Platform , any discrepancy in height of the Platform shall be graduallytapered into the existing Platform . The transition gradient shall not exceed 1 standard position of the Platform edge relative to the track provides for boardingand alighting of trains, assuming that the trains are built to the Requirements ofGMRT2173. It also provides for the passage of trains at speed, including freighttrains, in accordance with the Requirements for gauge the GB railway, which generally provides for network-wide utilisation of passengerand freight vehicles and open access, this standard Platform height is the number of studies have considered alternative Platform heights for the mixedtraffic railway, but the target Platform height has been confirmed as 915 mm.
