This listing is for a vintage Marx Mechanical Train Set #526 and a Marx Battery Train Set #2512, both of which are in original boxes.  The Mechanical Train Set has a wind up locomotive, and the Battery Train Set is battery operated.  Both trains sets show some signs of wear and the boxes are worn.  Both are untested, so you're buying these as is.  Condition as shown in photos.  I'm glad to combine shipping.  Please let me know if you have any questions.
