This is a Marx Railroad Over and Under Trestle Set with the original box, set number 1412. Has the Girder Design.
The box is not perfect but it shows a lot of the original design. It does have some pencil writing on the front, the names of Ralph and Ken. Items are very dusty. There are supposed to be 24 plastic trestles, there are only 21. The brown ramp item is marked Marx but I do not believe it is original to the set. The pile of black metal like clips may also not be original to the set. They are not marked but came in a box that belongs inside of the bigger box. Please ask any questions you have.
