On the switching scenarios, I can't get the locomotives to shift anything and I have no clue how to set up the locos. As a first timer to sand patch grade it would be helpful for a guide of how to set up the two locomotives so they work in tandem.
Check out the manual found here. Has a lot of good info, including MU (mutiple unit) setup. https://forums.dovetailgames.com/threads/csx-heavy-haul-sand-patch-grade-manual.25884/
...this should help, there might be some older manuals at the Steam website as well. https://live.dovetailgames.com/live/train-sim-world/articles/article/tsw-help
Don't worry Thomas. I had the same issue and really had me perplexed. Given knowledge of problems with getting locomotives moving from other countries I was checking handbrakes and everything. I was getting amps but no movement? But having reviewed the manual kindly attached in this thread... Of course the Brake Cut-Out Valve! Seen more seasoned players than myself make that mistake on Livestreams - not even sure if Matt P had that problem with 'Baby Bullet'?
