I used to live on a road behind a level crossing - there was no way out except over the crossing.
One morning they forgot to put the barriers up after the train. It had those half barriers - one on each side on the left side of the road.
So there's about 6 cars waiting, and we all know the train timetable by heart 'cos we do this everyday. So we're all out of our cars, standing around, listening, peering up the track, wondering what to do.
One bright spark eventually realised there is a phone in a box by the barriers, to call the operator. . (this in the days before everyone had a mobile)
But the point is that none of us were going to risk driving around the barriers.
I stalled on the crossing once. I'm sat there desperately trying to restart my ancient car, praying that the barrier warning lights don't start, thinking that if they do I'm going to have to get out and leave my car! That was fun. (my car did start!)
