Latest Updates to Standards

There are multiple updates to standards being published in June 2020. Key changes apply to preparation for winter, non-railborne plant for railway infrastructure work, driving cabs, vehicle fire safety, recording data and vehicle registration, marking and numbering.

RSSB hosted a live webinar on Monday 8 June 2020 where Tom Lee, Director of Standards discussed the new and updated standards published in June 2020. His presentation is available to view on SPARK.

Preparation for and operation during winter

Guidance note GEGN8628 has been updated to provide guidance for preparation and operation during winter.

Key updates include:

  • The guidance note contains a combined winter checklist. This checklist is an amalgamation of actions from Rail Delivery Group, Network Rail, and GEGN8628 to prompt railway undertakings (RU) and infrastructure managers (IM) for winter preparation. 
  • Events from recent winters leading to the freezing of conductor rails have been included in the guidance note; for example the potential for AdBlue (a diesel additive) freezing.

Non-railborne plant used for infrastructure works 

RIS-1701-PLT issue five, sets out the engineering requirements for non-railborne plant designed or adapted for railway infrastructure work. Whilst principally applicable to Network Rail and London Underground Limited (LUL) managed infrastructures, the document can be adopted by other infrastructure managers. 

Key updates include:

  • References to Network Rail within the engineering requirements have been replaced by ‘infrastructure manager(s)’ as appropriate. The term 'non-railborne plant' has been adopted instead of 'portable and transportable plant’ to better reflect the range of products covered by the revised document.
  • The product acceptance process previously in RIS-1701-PLT issue four has been transferred into RIS-1710-PLT issue two, point release one ‘Engineering Certification of Railborne Plant and the Assessment of Non-Railborne Plant’. 
  • Additional requirements and guidance have been incorporated from LUL document S1174 'Non-Railborne Plant – Design and Acceptance'. 

Driving cabs 

Multiple documents cover the requirements of driving cabs of rail vehicles (‘cab standards’). These include Railway Group Standards (RGSs), the Technical Specification for Interoperability for Locomotives and Passenger Rolling Stock (LOC & PAS TSI) and the EN 16186 series of European Standards. The six previous RGSs were reviewed to eliminate conflicts or duplication with other documents, and the remaining content consolidated into a single RGS and a single Rail Industry Standard (RIS).  

Key updates include:

  • Requirements in the previous Railway Group Standards that conflicted with the content of the LOC & PAS TSI and EN 16186 series have been withdrawn to reflect GB practice. 
  • GMRT2161 issue 2 has been published and contains only requirements that meet the criteria of a national technical rule (NTR). These NTRs which are retained from the previous RGSs are unchanged in their technical requirements, but now have additional rationale and guidance. Additionally, a new NTR has been created on cab interior emergency exit dimensions, to address a GB specific case in the LOC & PAS TSI. 
  • RIS-2761-RST issue 1 has been published which retains content that cannot be an NTR but reflects GB practice and incorporates additional rationale and guidance. 

Vehicle fire safety 

One document has been revised and one new document has been published. Several guidance notes relating to vehicle fire safety have been withdrawn and their content moved to the new documents as appropriate. 

Key changes include:

  • GMRT2130 has been updated to remove references to the withdrawn standard BS 6853. 
  • Tests for passenger seats set out in EN 45545-2:2013 were considered insufficient. A new standard, EN 16989, gives an agreed method for passenger seat testing and the associated acceptance criteria are in the forthcoming EN 45545-2:2020.
  • Standard EN 17084 should be used to assess toxicity of the products of fire.
  • GMRT2130 has been revised to remove any requirements that are not justified as National Technical Rules (NTRs). The remaining requirements from GMRT2130 have been written in a new Rail Industry Standard, RIS-2730-RST.
  • RIS-2730-RST generally requires compliance with the full EN 45545 series, including prEN 45545-2:2018 (to be published in 2020), EN 16989 for passenger seat testing, and EN 17084 for toxicity testing.
  • Guidance has been added in response to the recommendation arising from RAIB’s report into the fatal accident at Twerton.

Data recorders on trains

Following a 12-month review of GMRT2472, the guidance note was reviewed. All requirements that were not duplicated in other documentation were transferred to a new Rail Industry Standard - RIS-2472-RST.

Key updates include:

  • RIS-2472-RST now signposts the TSI requirements and requires compliance with both the functional and data sections of EN 62625-1.
  • The majority of the required data channels are listed in appendix F of EN 62625-1. Additional channels currently required by GMRT2472 are now set out in RIS-2472-RST.
  • Recognising the lack of a single definitive document setting out all requirements, Appendices A and B of RIS-2472-RST list all requirements for recorded data and functionality.

Recording of rolling stock data 

RIS-2706-RST is a standard on recording of rolling stock (vehicle) data. The standard has been updated to replace the references of RSL (Rolling Stock Library) and RAVERS (RAil VEhicle Records System) with up-to-date references to the current R2 system.

Key updates include:

  • RIS-2706-RST has been revised to reflect current legislative framework and the requirements for vehicle data in the technical specifications for interoperability for telematic applications for passengers (TAP TSI), and telematic applications for freight (TAF TSI). 
  • The appendixes have been reworked to align with the information required by the vehicle registration process. 

Vehicle registration, marking and numbering

RIS-2453-RST is a standard on vehicle registration, marking and numbering. The document sets out requirements for railway undertakings (RUs) and infrastructure managers (IMs) to manage the process for the registration of, identification of, and data to be displayed on, rail vehicles.

Key updates include:

  • RIS-2453-RST has been amended to eliminate duplication of content with RIS-2706-RST.
  • New requirements and guidance have been added regarding changing multiple unit set identification numbers.
  • Additional guidance on alpha codes and European Vehicle Numbers (EVNs) for freight wagons has been included as an appendix.
