Thanks, Mark.

More testing before the ops session, tonight.
NP A-5 4-8-4 (Oriental Limited) and passenger cars.
Just this one engine was derailing under Glacier (snow scene). Can't get to it (been that way for 40 years) so I used some small tin snips and cut a U shape into the scenery and pulled it back to gain access to the track.
Widen and beveled outside edge a bit to fix this one engine derailment.
Tested PRR GG1's (Bachmann) and passenger cars.
About twice the train shorted: not sure why as no derailments and I moved each car laterally to see if any intermittent shorts but none. Not sure if, momentarily, exceeding max amps. Just hit the reset for the CB and all's good! Two powered engines and 14 lighted cars (8 are brass so heavy load). With the brass cars having metal trucks and wheels, sometimes it sounds like a car derailed but nada.
D&RGW L-131 2-8-8-2 (PFM United) and BLI lighted zephyr passenger cars.
Just noticed that when backing up a train past a red signal, it changes back to green so able to proceed forward again, as normal clear.
Ran train over 850' of track and one spot, the lead truck came off going with the points. No problem when engine went against the points. Again, points were a little lower than stock rail so beveled the inside edge of the stock rail. Also, gauge was a little wide. Another spot where everything else works great passing this area but one engine and in only one direction!
Glad I made most trees removable as it was a lot easier fixing this turnout with the trees removed!
