This little train #31015 (MSRP $4.99) was something I bought just to get my order over the threshhold for free shipping but it's a lot more fun than I imagined. I bought two so I could make a car for the engine to pull... Now I'm going to order a few more so I have pieces to make some custom cars.
Anyway I know officially these don't fit on LEGO tracks but wondering if anyone had any success making some kind of custom track that does work?
