How about an emergency alarm/buzzer that alerts incoming trains to anything on the tracks -- people or obstructions.

Low tech, but would offer a way to help people without risking your own life.

You'd need surveillance or something to prevent people from using it as a prank though.

Trains take miles to come to a complete stop. Unless the person is standing in the tracks for minutes these would be ineffective.

Massive freight trains with hundreds of fully-loaded cars take miles to come to a complete stop. Small passenger trains are a different story.
