It is a cold December day in 1949 and the shifters are busy. An H10, usually working a local, is working the yard today and is the yardmaster's favorite engine. Like the C1 in back, it can move a lot of cars but unlike the C1 is more reliable on the less than perfect track of the east yard. The H10 was a good engine and the Pennsy kept many of them to the end of steam. The C1, however, will be gone in a couple of years.
The engines are Weaver models and the cars are Atlas O.
