CJ just asked me what level crossings or train crossings were called in the USA. Trains in the US, Canada, Australia and New Zealand are treated rather differently to trains in the UK and much of the mainland Europe that I have visited (as far as I can recall anyway). In the UK trains are generally fenced off from public access even across many many miles of Scottish moorland. The concept of a train sharing a public road bridge with cars and lorries without even a set of lights of a barrier is incomprehensible in the UK. However in South Island, New Zealand I recalled travelling across a bridge which also carried trains and there was nothing more than a 'Give Way' sign to indicate to motorists that oncoming vehicles, and presumably, trains have priority!
The approach indicates a railroad crossing (should it not be 'sharing') and that cars should give way.
I can see the cars that are coming.
Now what happens if a train appears?
