The Key Train Requirements (KTR) document aids rolling stock procurers, manufacturers and system suppliers to incorporate research and good practice in train design which aren’t already covered in standards.
The document covers technical requirements as well as performance, environmental, operational and passenger facing aspects and communications and diagnostics. The latest version (six), includes over 100 new or improved entries, a new expanded section on passenger seats, and a new section relating to on-board catering equipment.
Three accompanying Excel spreadsheets have been produced to help incorporating the requirements into procurement databases
The KTR document and the spreadsheets can be found on the RDG website here:
There you will find the main document and three accompanying Excel spreadsheets of the requirements: the main document, Appendix C Toilets and Appendix F Monitoring Infrastructure.
Things moving apace, we are advised work on Version 7 is already underway.
