I'd really hope that modern signalling prevents trains entering signal blocks with other trains in (or can't confirm there's no train in) them.
As in actively prevents, locking the brakes at the previous block, rather than allowing drivers to miss or ignore signals.
We've had plenty of issues with this to learn from in the history of railways for it not to be a high priority.
E: aye seems that way :)
> In order to prevent a train from entering an occupied block, each signal has a mechanical ‘trainstop’ next to the track. This device applies the brakes of any train which tries to pass a stop signal.

- bobthepanda 3y agoThe issue is during evacuation, people may not have the sense to stick to the track their train is stuck on, and may spread out into a parallel track.
- corobo 3y agoThat is an issue for sure, but I'm responding to the possibility of a train hitting another where the passengers have opted to stay on the halted train
- kevincox 3y agoThe walking passengers may enter a block that their train has already cleared. So you can't really assume that wherever they walk will be locked.
- corobo 3y agoThe comment I'm responding to is concerned of the risks of staying on a halted train. No walkers in this hypothetical. That is for sure an issue, but not the issue I'm responding to
