I did the tutorials for all three CSX engines. But when doing a timetable service, I can't get the locomotives to move. Looks like something is still applying brake force, even though I'm confident I followed the exact same steps as explained in the tutorial. When throttling engine is generating amps/RPM. I've also watched the brake gauges because I know it takes time to release/apply pressure in long trains. But I can't figure it out... Even tried enabling the Generator Field switch (which was ON in the tutorial but OFF in the timetable service), and various settings with the brake cut-out switch (which weren't explained in the tutorials). So, what am I doing wrong here?
