This is my Atlas N GP40-2, with a Zimo MX620 installed in it. Runs nice and slow (decoder software rev 9.9, key to smooth slow speed seems to be to set CV9 to 79). The problem is due to slop in the gear train if there is a very slight downgrade the loco bounces back and forth a bit. First part of video show smooth running, second shows the bouncies. If I turn the loco 180 on the same piece of track it still bounces as it goes left.
Holy SHIT!!!!!!!!!!
