This set was recently reworked with more detail added.

The tracks are handed, and include very fine detail. The track face has chevrons and the track teeth are solid. The inside of the tracks is a little rougher than the outside, but is easier to clean without losing any detail.
Each set contains 4 sections of left track and four sections of right track. These will have to be heat-shaped around sprocket and idler.

Note that Modell Trans also offers this type of track.
