The last car on a freight train, the caboose, carries men in the train crew as well as emergency equipment.
It is constructed with either a raised glass cupola or glass bays, giving those in the caboose a good view of train
operations.

are ready for a description of the different parts of the typical railway car. The next chapter discusses wheels
and axles.
