TD;DR; Add checkbox to train station interface to require that train stops at the station in order to use the station for pathing. Why: To give the player exact control of how train's path finding interacts with stations. This increases the players choices for creating optimal rail networks. Details...

Is it possible to have a mod that has a gui, but does not affect gameplay, that would not require Synchronization? I'm trying to create a ratio cheat sheet / calculator mod, which would display a window with handy building ratios like pumps -> boilers -> steam engines 1->14->10. The mod would not be...

Thanks Yoyobuae, great breakdown! figured it was something simple.
