I just picked up this NOS (new old stock) engine - cheap- from Ebay. I go over the features and give some operating tips to help when using these older engines. This works great with Lionel track, cars and accessories.
This engine is a model of a General Motors Electro motive division (EMD) GP20 originally built in the early 60's. GP stands for "general purpose" It is considered a Road Switcher as it can work the main line or a local yard.
