For a used HO scale Diesel Engine this item is great. It's a perfect replica down to the last design detail of the original Burlington Northern Diesel engine, the paint design, the windows, the built in steps to the engine cab, all very well designed and it's in good working order. For a used item I can find very little wrong with it, it's been very well taken care of . The wheels and their casings are also well made and designed and in good shape I am very happy with this train engine. Well worth what I paid for it.
