There's not a sensor that can detect another train with enough warning to matter. Stopping takes miles, and turning isn't an option.

So you detect them miles away. It's a real-time analysis problem: assign a latency equal to the longest time required to react and that's the time you have to detect an oncoming train.
GPS...?
