Hi, on one of my F7 units I noticed that it runs about 1/3 slower in one direction than the other. I'm running DCC. Ii is running in a consist with other 3 F7 units (same Proto 2000), so it ends up being pulled in one direction by the other engines, but is fine when going in the other.
What could be the problem? I figured if anything mechanical, it would've run badly on both directions. Any suggestions? Other 3 units that I have don't appear to have same problem.
