HST door locking operation

[Crossover]

Try a trip to Hereford!

Done that before too, where the guard doesn't only have to worry about platforms lengths, but also having a presence in the rear powercar through Ledbury Tunnel!

Slightly different maybe, but at Green Lane on Merseyrail the front set of doors on a 6-car actually open into the tunnel wall. I've never seen anyone fall out yet....
