Some of the HST 125s have been rebuilt and sent to Scotland and Cornwall. They're withdrawing them from GWML, at least supposedly. What I was thinking of though was that it was the first train type in the UK at least to be officially classified as "high speed train". As for the door handles, despite having used those trains since the early 80s (certainly long before I was old enough to get drunk in the buffet car – in fact I don't think I've ever consumed alcohol on a train other than in the compartment with a big group travelling on a multiday sleeper train journey) I really don't remember them ever having internal door handles. I remember having to lower the window and use the external door handle before the falling out stuff, which led to the introduction of internal press buttons. And the problem, AFAIR, was (in addition to drunken passengers) that the doors had a two-stage lock; they would latch before being fully closed, which meant they appeared to be closed but could still be opened (either deliberately using the external handle or far more likely by leaning on them) from inside. So they introduced interlocks, meaning the train can't move until doors are locked.
