We went on the train last year (great experience) after being bumped the previous year as the lack of locking doors caused the firm to cancel trains for many weeks at the start of the season. Forgive my ignorance, but is it because the train is running on a mainline that the requirement for locking doors is needed?
The Railway Safety Regulations (1999) regulation 4 required the removal of rolling stock with hinged doors from passenger service unless fitted with centrally controlled door locking from 01 January 2005.
RSR only applies to passenger stock operating on railways with speeds above 25mph, hence does not apply to the vast majority preserved railways (AIUI the Great Central Railway has a specific method of operation). RSR does apply to trains operating at up to 25mph on railways with other trains operating above this speed.
RSR regulation 6 permits the Office of Road and Rail (ORR) to issue operator exemptions, which may be conditional. For many years ORR issued such exemptions to regulation 5 for main line operators of historic rolling stock typically on conditions of both:
- secondary door locks being fitted (typically shoot bolts)
- stewards operating the doors & locks, usually a minimum of 1 steward per vestibule (adjoining coach ends)
ORR clearly signalled in 2018 that the 5 year regulation 5 exemptions issued that year (typically expiring early 2023) would be the last.
NYMR‘s exemption was renewed in 2023 with additional limitations:
- Between Grosmont and Whitby only
- Maximum speed 25mph (line speed IIRC is 40mph)
This has been deemed acceptable because there are no passing loops between Grosmont and Whitby, and therefore there can only be 1 train on that railway.
A few other operators were granted extensions to their exemptions on the condition that they had an active programme to fit CDL.
WCRC have refused to fit CDL, and regarding The Jacobite, Fort William to Mallaig has ScotRail trains running at up to 55mph and passing The Jacobite.
For completeness, RSR regulation 4 required the removal of mark 1 rolling stock without crashworthiness enhancement work from the same date.
