First of all; thanks for the mods! Playing without your train changes just feels weird at this point, that's how good I think they are. There is only 1 thing I wish this mod had, that it doesn't currently have.
The Rampant Arsenal made the grids of locomotives bigger, allowing you to give them reactors and shields and such. This made a lot of sense to me, since I only play on railworld deathworlds lol. I have since stopped using that mod because of other reasons, but I really enjoyed that part of it. If there was any way for you to add potential train equipment to your mods, that would literally be perfect.
