This is an excellent buy especially at the marked down price. I bought this engine because of the different road number than the other two I bought. I plan to use it for a park type static display when I'm not running it. The paint quality and detail is amazing. I had planned to do some extra detailing on it, but none is needed. The engine runs great. The only problem I can see is that it takes a wide curve to stay railed, but the listing page warns you about that. It is also quite heavy so you may want to check your track connections to be sure it won't cause the rail joins to move.
