Depending on how long the train will be stationary, depending on the person who can’t alight via ladders, eg wheel chair, limited mobility. Then I have know them remain on the train until It is rescued and alight at the next station.Yes- that could be very possible. I suppose we will find out in the next 10 minutes.
I wonder what happens to those who physically can’t climb down? Do they get some sort of ramp or other assistance or do they stay on the train?
If train would be there a long time. Then I’ve know the Fire Brigade called and they assist with removing them from the train.
