Here is a Lionel 0-4-0 dockside steam engine switcher. This one came in a set in the 1980s. It is a simple engine, but really cute. With that red and silver, it is the perfect Christmas engine but can also run year round since it is standard Rock Island.
This one runs on DC POWER, so it can run on the same power pack as your HO, N or G.
Forward and reverse operation
Cab number 8700
Boiler number 8
CONDITION: C-6. Tested and runs with DC power. Looks good. The cosmetic whistle on top is chipped off and the front headlight assembly is missing (it is just cosmetic, not a real light).
