This is just some of the track available at Nostalgia Hobby. They carry original, still in package Aurora Model Motoring and Aurora AFX track. I've seen pieces like AFX Flex Track, AFX 4-Way Intersection, and 6" Aurora Speed Corners. Used Aurora and Tomy AFX track is also available (but used straight Tomy sections are rare). Of course, the full line of new Tomy track is available.

Tyco/Mattel track is also available, including the gray/beige US-1 Trucking tracks. I don't think Joe offers used Tyco track any more, but he may have the railroad crossing sections available. I have seen that there.

Joe also sells Life Like/Rokar track, also only new pieces. He doesn't carry a whole lot of it (usually I see 15" straights and 9" curves), but he will order specific pieces for you.

Lastly, he does have sets for sale. As you can see in the store window on the main page, he carries a variety of Tomy/AFX sets, as well as others like Life Like.
