O Scale 4-8-4 Steam Engine #3780 AT&SF - painted- unknown maker- tested- preowned. One of the hoses on the top of the engine is off but replaced and taped down. We ran the engine on our test track and it had a hard time moving forward and reverse. Would move okay and then die out. Nice details on the engine, nothing broken (except the hose on roof off).
