This is a collection of track transitions to connect the 3 Lane JR Japan cup track to a 2 Lane JR Oval track, with an extra single custom lane branch off. There are 4 models provided at this time, a Straight section, this jogs the single lane out but continues it on straight, then there are 3 curve options for the single lane, a 15, a 30, and a 45 degree turn.The transition is roughly 200mm Long, the 45 degree single lane track makes that model longer to make sure the track doesn't get too small for the cars.
