This was designed to compliment the Pixar Cars Tracksets. The ends of this road piece are designed to connect to the ‘older’ tracksets with the thicker triangular connection arrows. The ‘newer’ tracksets have much smaller connection arrows and are not compatible with this model.

My son is a huge Pixar Cars fan and has several of the tracksets. However, we didn't have enough track pieces to combine the tracksets together and I can't seem to find anywhere to buy them. This model was created by me based on some measurements from existing tracksets that we own.
