Ftaod: It's clear that random red lights on a railway platform with clear potential to confuse drivers and create an unsafe situation is a hazard best eliminated.
So why the endless searching for laws or regulations (which you know probably do not exist).
1) it's clear that it's a hazard best eliminated (see above)
2) This is confirmed by some of the TOCs so it's not an urban myth. Not all TOCs it's true, but I found four instances.
3) At least some station staff are aware and will inform or remind cyclists if they are unaware or forget. I know this from first hand experience and at least two CCers have posted to that effect.
Is that not enough to establish the facts of the matter? Do we really need it to be explicitly validated by some minor law or other?
Could it be more widely communicated? Sure it could. But it isn't so we have to live with that. People can be forgiven for not complying with the
law regulation practice if they don't know about it. And once they do know about it they should change their behaviour.
AS we are all sensible people on Cyclechat, and we've all heard about it, we will all take steps to extinguish lights on platforms.
Everybody's happy.
