This is a weird locomotive which i got from Japan through a friend, Benny. The shunter actually based on Japanese protoype which is DD12 but has US Army livery. Not really sure if US Army even uses this livery. Microace website lists this as “Novelty Loco”. I guess they did it just for fun.
Unlike Tomix C-Type shunter, this one doesn’t come with traction tyres. That means it’s pulling power kinda sucks. So far it can manage like 10 cars if the tracks are perfect flat.
