The Marx 4222 steam type electric freight train set was a hybrid set from the early 1950s with a plastic 400 locomotive and four wheel plastic tender paired up with 6 inch tin freight cars. At least four variations of this set exist. They all came with the same locomotive and tender and a New York Central 20102 caboose. The differences in the variations are in the type and number of freight cars.
This specific set illustrates the challenges of collecting Marx sets. Marx used the same catalog number on multiple variations in the same decade. It’s not something Marx did all the time, but someone at Marx must have liked the number 4222.
