As for some of the knickers in a twist brigade (nice to see you're having a rest from

TOCs▸ control you would be able to release doors or detrain, I would however assume that in this situation the signaller and
FGW▸ control were rather busy dealing with a signalling failure and would like all staff on the ground to follow instructions as safely and efficiently as possible to enable a contingency service to run.
