The Dam

There is a dam that runs across a river on Toby's line. During a flood, the river flooded, and the dam partially collapsed. Its collapse caused Toby to be swept downriver, narrowly avoiding a waterfall.

It only appeared in fifth season.

Trivia

 * In real life, a railway line running over a dam would be incredibly dangerous.
