The alarm sounds as the doors are closing. It doesn't stop when the 'leaves' start to move.
On quite a lot of stock it in fact does stop when the leaves start to move, or certainly did until PRM-TSI modifications on all 1980s and early 1990s DMU and EMU stock. But even so, the doors are factually not closing until the leaves move.
If I'm standing by a conventional door on the house and shout that I am going to close it, is the door closing? Clearly not until I start to move it towards the closed position.
SO at the point in which the alarm is sounding, the doors are in fact, moving. It's pointless and dangerous hair splitting.
It's not. To drive correct behaviour in a safety context you absolutely have to be clear and unambiguous. If there is a possibility for misunderstanding, it HAS to be removed.
What is dangerous is that it is possible to split hairs. If it is, it's also possible for there to be a genuine misunderstanding given that people have different perceptions of risk.
If you hear the alarm, move away.
Then that is what the notices etc should say.
FWIW, I genuinely don't understand why there isn't also a prominent red light, if for no reason than to help those with hearing issues. Only the Class 156 has a substantial visual indication of doors closing, and it's a flashing white strobe. In Germany it's usual to have a bulb-shaped red lamp above the door *and* on the leaf - then you could have a campaign along the lines of the successful CDL "it's fruitless if it's not orange" campaign - "if it's red - stop!" would be a good way.
The railway is just doing its usual and shouting off about passenger behaviour while not actually doing anything positive to attempt to change it. Or rather, only Merseyrail is - their new stock (and only theirs) is to have red and green LEDs around the door to indicate when it is safe to board. Why is this not standard on all new stock?
