Here are 10 ways to say that idea for a 7-year-old:
- Trains don’t have steering wheels; they follow the tracks.
- Trains don’t steer — the rails tell them where to go.
- Trains don’t need a wheel to turn; the tracks guide them.
- Trains can’t drive off the rails; they stay on the tracks.
- Trains go along the tracks, so they don’t use a steering wheel.
- The tracks show trains the way, so they don’t need to steer.
- Trains follow the rails, not a steering wheel.
- The rails lead trains, so they don’t have to turn with a wheel.
- Trains ride on rails, and the rails decide their direction.
- Trains travel on tracks and go wherever the rails take them.
