A cake made in the shape of a choo choo train can be purchased or if you're bold enough give one a go yourself. Cupcakes could be decorated with little toy trains too! Sugar cookies, iced and decorated in the shape of a train would look pretty served on a tray!
Add paper plates, napkins and cups with a train theme. Party favor boxes could be used as a centerpiece and handed out to your guests for a memorable keepsake as they leave. So many great ideas, let your imagination go here!
