Last week we saw the image Jack Delano captured of a brakeman flagging his train on a cold January day in 1943. It’s now nighttime, and he’s still at the Indiana Harbor Belt yard observing and recording the crews in their labor.

We’re adjacent to the cattle pens here, and the switchman is signaling the engineer to stop. He’ll line that switch for the other route, and then signal the engine to come back.

Railroading on most railroads is a 24 hour/day proposition, and work goes on regardless of the time or weather.
