This is the perfect item for those who have decided to change all there track to a more realistic size, expanding an existing layout or building a new layout, 100 piece of track, each piece of track is 30" long and is packed with detail (yes, even track has detail) you get enough track in this box to make a loop around the UP 844 with track left over, this is enough track to do what ever you want and mess up and loose a few pieces of track and still finish your project with some left over.
