We just learned about the Chimney.
Another part of a locomotive is the Headlight or headlamp.
The headlight isn't really for the people driving the train, because they are going too fast to be able to stop if they saw something.
It's really meant to warn everyone to get off the tracks and to stay out of the way.
There are also workers at stations who need to know the train is coming, and they can see the light from very far away.
