Continuation of BigLobe Plarail Museum

Its not easy to spot this as the U Turns are extremely rare. I tested the faster trains on the old type but no trains were derailing. It could be for extra safety purposes. Interestingly the ends of the U Turn are marginally tighter so it is harder to fit it on the double tracks.

Another example of this mold change happens in the first generation big iron bridge where the latter type has its ends of the bridge diagonally cut, and the early type had flat vertical edges. The change was made so that the trains don't collide with the ends of the bridge while making a sharp turn in.



Another example is the Y rails. Left is newer, middle is old and right is oldest. The diverter is differently shaped, the joints are omnidirectional so if you flip it backwards it is still the same diverter layout.
