Wilton 3-Dimensional (stand up) Choo-Choo Train cake pan. (Or use one side of the pan for a lay-down type of cake.) 1974. Has a couple pin-point size marks, but these will easily be covered by frosting, IF they even show up at all. Does not have insert, but decorating instructions can be found on wilton.com. Email me if you have problems locating them.
