Time for me to start tacking random railcars to those trains and throwing up videos of their operations lol. IIRC, when I tried these trains a while back, I didn't like them bc you actually had to start the prime mover before being able to get underway, and they didn't come with too many instructions lol. But I was too lazy to modify them. I guess I can have the first trainsets done by the end of the weekend haha.
EDIT: with the F9s though, since the F7s are community only at the moment.
