Dynamic Brakes on the SD40-2 It's not working anymore. I'm doing all the right procedures, including leaving the lever on the setup position for a while before start applying more power. I was doing the service Q250 18:30 and the trail loco was an AC4400 set-up correctly as trail unit. The climbing was ok, notch 6/7 power was enough cause I had 2 bankings on the rear, but the descent to Rockwood without the dynamics working and a 0.6% downhill with 5.000T cost me a spad in the end of the service...
