This is a nice Marx Steam Type Electric Train Set in its original box.  Set number 4205. Comes with the #400 locomotive, Tender, Gondola, and Caboose with Track and Transformer.  I tested it on my test track and the engine and transformer work.  I have a video of it running but Ebay won't let me upload it.  I think I can send it on request.  This set came from a train collectors estate. Email with any quesitons.
