Great work by everyone ! Too many posts and photos to reply to each one. Been busy tying up loose ends. Got the chandeliers installed in Union Station, and installed more cross hatch window dividers in the large arch entry.
Decided while the front center of the layout was under construction update with the Pennsy Block retaining wall upgrades, I should take the opportunity to install new Kadee Uncouplers on the Mine Run. Managed to come up with a "set - up" that produces pretty reliable and repeatable "delayed coupling" action which I want to have to spot hoppers under the Coal Tipples, so I figured just make up a bunch of assemblies that are completely super-glued together and ready to install on either Gargraves or Ross track sections that are fully ballasted. This is working well, all I have to do is drill out the glued ballast, and install two flat head countersunk #6 steel screws which hold the bar magnet assemblies in place while the siliconized latex caulk applied to the top of the ties holds everything in alignment. The small metal strips are from the Green File Folders that one uses in old school file cabinets to hold and organize manila folders. It's perfect size stock for this job, dirt cheap and easy to cut to length.
