Couplers and Drive Train dissection

Some early good news, it appears that the couplers are the correct height. I dug out my Kadee coupler gauge from the basement, and tested the couplers. Both lined up pretty nicely with the gauge. The little trip wire may need to be adjusted up, or I may just chop it off and attach a scale air hose.

I dissected the rear truck to show how it's done and what's inside. I'm going to replace the stock wheels with NWSL aftermarket parts. After I replace those, I'll lube the gear box and check the gears for flash and other rough spots.
