I got the mod to load, and found the config for the track. I was able to add some space between the tracks. My next question is, what would control the ballast texture and the ballast color/texture bleeding over to different tracks laid beside it? The "ballast" texture that normally comes under the track set changes to this brown color instead of the standard grey. I have zero clue where to look as this is my first try at changing anything in this game.
The tracks on the right are the 760mm Infrastructure track. The area in which this track sets has been shift painted to the grid so I could see how the track bed changed easily.
