We just learned about the locomotive Headlight.
Another part of a steam locomotive is the Brake Hose.
Remember we learned before that when the engineer wants to stop the train he pulls a lever that uses the high pressure air brakes to push the brake shoe and stop the train.
When a train has a lot of passenger or supply cars behind the main engine, they can have brake shoes to help slow them down too.
The high pressure air brakes have tubes that go from car to car to bring the air pressure that closes the brake shoes to slow down the train.
