As of tonight I shimmed the last turnout!
Altogether I shimmed 50 turnouts on the main layout. The ones I did not shim were the ones in the yard at El Dorado, the main yard and the ones in Malvern.
So far those have not shown any kind of issues with shorts or derailments, so I have left them for now. The ones in the main yard I didn't touch as sometime I see ripping up portions of it and realigning at least one end and a few turnouts eventually.
After I shimmed each turnout I would check it with a lightweight car by running it back and forth, then I would run it through and force the trucks to the guardrail to see if I could get it to pick the frog point. If they passed I would then run the train that found several shorts.
This was made up of two KATO E8's and IMRC FP7a. The E's would normally be the ones that would find any shorts due to the longer three axle trucks. The train consisted of one Wheels Of Time express baggage car with three axle trucks and metal wheels and 8 more TOFC cars, MTL and Trainworx. The Trainworx cars have stock metal wheels.
After tonight I was able to run this train at or near prototype speeds without shorting anywhere. next is to try running some of the 6 axle freight locos: SD40-2's, SD45, U30c's.
I have to admit the black styrene looks a lot better than the white did, but for some reason the black styrene seems to be a bit tougher to get glued in place? But they are all done for now.
What's next? Well the first thing, I need to get the layout and basement cleaned up. Then I plan to get an ops session ready to go first, then I hope to get started on some scenery, starting with areas of the backdrop first.
