2 Suggestion:

• Icons instead of a projection of models (for disable freeze in inventory menu)
• Optional "locomotive control" (maybe gui). Because opencomputer is too difficult for usual players (most players).
  P.S. Sorry if similar suggestion already are.

• B:enableIconCache=true in immersiverailroading_graphics.cfg
• You can do some basic stuff with redstone and the loco control augment. Hit it with a redstone torch to change modes

Wow, thanks for help!
