Train at station, the cargo wagon is perfectly aligned with the inserters

Train around a 90 degree corner, the second set of cargo wagons is misaligned by one tile

Train around 180 degree corner, the second set of cargo wagons is aligned correctly

Train takes two 90 degree corners to return to original aligment, the second set of cargo wagons is aligned correctly

Train takes two 45 degree corners and one 90 degree corner equaling to a 90 degree turn but totalling 180 degrees of cornering, the second set of cargo wagons is misaligned by one tile

This is an issue because train stations are locked to the 2x2 grid and thus cannot be adjusted to allow the train to always be aligned to the inserters.
