The huge coal towers in big freight yards can fill several tenders at

once. Often, while the loading goes on, ashes from the locomotive’s

firebox get cleaned out at the same time. There is a dump pit under the

tracks, with little cars that run on their own rails. After a little car

is filled with ashes, it can be pushed away and unloaded at the ash

heap.

When Sam pulls into the next big freight yard, his part of the run is

finished. After a while he will board another engine and take another

freight train back to his home station. He has a regular schedule for

work. That doesn’t seem strange these days, but Sam’s grandfather would

have thought it was something miraculous.

In the old days, grandfather never knew what time he’d have to leave for

work. Sometimes, when he was just ready to blow out the kerosene lamp

and go to bed, there would be a knock at the door. On the dark porch

stood a boy, still panting from a bicycle ride up the street. He was the

railroad call boy, and he’d come to say that an engineer was needed

right away. Grandfather had been assigned to the job. So he pulled on

his clothes and went off, no matter how sleepy he was.

The place where Sam leaves his train is called a division point. Other

men will take over all the cars of redball freight and speed them on

another division of their trip. Let’s see who these different

railroaders are and what they do.
