I can't tell everyone how much I appreciate the advice. But much of what Dan just said - "Since it is the USA Trains GG1, should not have a power pickup problem and the MX699KV has super caps to keep the decoder alive" - is literally like a foreign language to me. I'll keep at it though, and those trains will run someday!

Super caps are a temporary high capacity capacitor power storage device. I installed these in the LGB stainz loco and after running about 1 minute on DCC with lights and smoke on and full speed, I picked the engine up off the track and it ran for over 10 seconds ion the air!! This is how long it took for these super caps to discharge. Look at these as a short term battery for power, but have no lead or acid to degrade and can be recharged a hundred thousand times or more.
