This is a unitrack set HO guage. It is in almost new condition. It was only used at the most about 2 times. It has been lost in a closet up on the top shelf. This was a gift for my son many years ago and he wasn't allowed to use it without adult supervision. It includes 7 straight track, 1 feeder track, 16 curved track, HO rerailer with unijoiner remover, and adapter cord.
