Also in view ( extreme right) is the green push button the BPQD. It happens to be my fav button. When the loco is hauling a huge load up a steep gradient a slight wheel slip occurs and if the diff between current of two TMs exceeds 125 amps ( This again is very conservative and needs t be raised to 200 amps at least.) the QD gets energized and regression occurs. However if one keeps BPQD depressed than the QD gets bypassed and no regression occurs. The best thing to do would be to keep BPQD pressed when one wants harsh speed gains.

That red Button is something like an emergency shut down switch. You can see an arrow mark next to it. The button has to be pressed and than rotated. It shuts down everything. In case some one who follows the policy of "go forth where no man has gone...

That red Button is something like an emergency shut down switch. You can see an arrow mark next to it. The button has to be pressed and than rotated. It shuts down everything. In case some one who follows the policy of "go forth where no man has gone before" and presses the button just to check it out than everything gets shut down.To restart one has to cutoof the batteries in the loco and than restart after a couple of minutes.
