That sentence means trains can’t turn on their own — they follow the tracks. Here are 10 easy ways to say the same thing:
- Trains can’t steer; they follow the tracks.
- A train can’t turn like a car; it stays on the rails.
- Trains go only where the tracks lead.
- The rails tell the train which way to go.
- Trains must stay on the tracks, so they go where the tracks go.
- A train rides along the rails and doesn’t steer.
- The train follows the line of tracks, not its own steering.
- Where the rails go, the train goes.
- Tracks decide the train’s path.
- Trains stay on the rails and go the way the rails point.
