Well for what it is worth, I found a couple of issues caused by me:
1) With my bad eyesight, one of the two A units was still set to program (cleared and reprogrammed engines, both set to run now).
2) On two places on the layout where there are curves, the front truck of the lead engine was de-railing. One of those curves are fixed now and does not derail, but the other had no visible defect. It is a O-31 curve, but this is a Lionel PWC...cant imagine that derailing at slow speed on a O-31, is not that what they were designed for?
3) Stall and Speed Limit were not set
4) Cannot seem to clear out and re-set the stall and speed limit values and the number boards are still flashing (noticed they started flashing after I pressed the set button in program mode during programming of the engines).
5) Might have pressed set twice in programming mode and thus caused (4).
As a result, the only outstanding issues now are the flashing number boards and the stall/speed limit settings.
