Here we have, a nice, Marx, electric train engine. It has the # 490 on the engine, and is marked on the side, in a circle, Marx, U.S.A., Toys. I think it is from the 1960's-70's, but you collectors should know for sure. It is in excellent condition, and runs. It measures 9 1/2" long, 3 1/2" high, and is 2 1/4" wide. It has the hook up at the rear of the engine to add the coal car. All the moving parts are metal, as you can see in the photos. No cracks, or broken places that I can find. If you like to collect electric trains, and need an engine, here is a good one for the collection!
