More post ops PM'ing:
Well, that will definitely cause some derailments (two items):
1) Ground throw too close to track.
On the 3 new passenger tracks installed, I put the ground throw too close to the track.
Some piano wire fixed that.
The end ladders on the cars were hitting the ground throw and causing derailments. Naturally, this new turnout was at the very beginning of the passenger yard!
2) Gunk on the wheels. This passenger train was getting some derails. Checked the trucks and there was 'tons' of gunk on the treads which, definitely, will affect the reliability of the RP flanges. Q-tips and alcohol used to clean them: left set of wheels clean, right side with the gunk. Lets see, 12 treads per car, 15 cars, mmm, that's a lot of wheels to clean!
Also, a lot of Q-tips used!
Used the PRR T-1 4-4-4-4 (which pulled the ACL cars in the 'real' world) to test the PM'ed cars on the mainline.
Much better, ran the entire 400' mainline heading East, uphill with no derailments 
The T-1 had no problem pulling the cars. They are IHC cars from the 70's, very light (I take them straight from the box to the track) so the T-1 can handle the set.
I'm hoping my other 13 passenger train sets aren't as bad as the ACL's were! Surprised they got so dirty so quickly as the passenger trains are fairly new (obtained in about the last 1.5 years) and they have intermountain metal wheel sets.
That's it for tonight: will check the other passenger cars, tomorrow.
