Unsolved problem =-(

Can we assume it's an open circuit and not a short?
Get a piece of wire and use it a a jumper after your train stalls.
after the train stops, put the jumper on one rail where the train ran and touch it to the same rail where the train is. If the train starts, then try moving the jumper up close to the back of the train (I've said train; read locomotive) and see where it starts.
If the loco doesn't start, repeat using the other rail.
I suspect that there is glue and/or ballast where the points meet the rails.

In model railroading, there are between six and two hundred ways of performing a given task.
Most modellers can get two of them to work.
