How about this modification of the problem:

The train itself is electrically conductive between M and N.

The bridge is an insulator between A and B, but is electrically
conductive from A to the left, and from B to the right.

A voltage source is connected to A and B.

If (M is over or to the left of A), AND (N is over or to the right
of B), current will flow, otherwise no current flows.

Does current flow as the train passes over the bridge?


Now that I think about it, this isn't going to work because the
electric current itself is limited by the speed of light.
