Comes with 1 wind up engine, 3 train cars, 1 caboose, 1 - 2 piece metal tunnel, 4 plastic power poles, 16 metal track pieces (1 track piece is missing a connector pin, but still works & two track rails have come unwelded to base as shown in photos, but also still work). The coal car top has come unattached to it's base. There are metal tabs that go into holes on the base, but it won't stay attached.
The wind up engine runs but seems under powered with the train cars attached, needing to be nudged along. I think this is because of the rust that is present on the track so it's not as smooth as it could be. The track is slightly warped and does not sit completely flat on the floor, but the train is heavy enough that it doesn't seem to be a problem.
