LOL, that would work but it's not in stock with a delivery date of unknown, which usually means a long time, if ever, at Walthers. If this is really important to you, pop for the $80 and don't worry about the warranty. After all, it's just a motor and some wires in Thomas and it's not usually hard to fix if something goes wrong. Tomix has a good reputation in Japan of building quality stuff so I wouldn't worry about it.
