Amazing slot car set. It looks to be complete with controllers, track, fences, power pack etc. Also 2 HO slot cars . This is a very large track. It has 14- 9" Straight tracks,12-9" curved tracks, 1-9" terminal track, 5-15" straight tracks, 2-9: lane changers,6-12" radius curve tracks ,2-9" curved tracks,"Nite -glow" fences and poles, track tiers, etc. I tested the cars and they work great. I have not set up the track. It has a Sears sticker on it and was purchased new there. Wow it is the biggest set I've ever seen or sold.
