Bachmann Highballer Chessie System N-Scale train set. Item No. 24301. Tested and working! Set is complete with ring of track, power supply, track connector wire, locomotive, and three cars. Item is used but in great condition. The track can only be assembled in a specific way, as is. The track connectors are on really tight. Someone with knowledge of model trains might know how to remove those without damaged the tracks. That's not me, so I'm leaving them alone.
