TL;DR
Please revert the "side note" from Upcoming breaking mod API changes 0.17.56 to make Rail Bridges work again.What?
Revert the change, that made the rail bounding boxes hardcoded. Let mods alter the rail bounding boxes if they want to.Why?
Because not denying modding of the rail bounding boxes enables us to have rail bridges in the game. Bridges are one of the rail features wich you don't want to implement and where long thought to be impossible to add by mod in a UPS friendly way.Recently, DaveMcW made a mod using rail segments with altered bounding boxes to implement bridges. It only works with modable rail bounding boxes.
