TL;DR
The train UI map settings (in regards to which icons are shown) reset with every restart of the game and do not get saved. They always default to show nothing but train station names and rail signals (which is basically never what I want to see).What to do
Save these train UI map settings in the savefile (like the regular map settings) and restore them on load, so we don't have to set them manually each time.
Why?
One small annoyance gone, and I think they should be saved anyway, since they are a state of the UI that players can modify to their liking. Makes no sense to reset them every time.
Other than that: thanks for creating the best game ever made!
