Been working on a few upgrade projects. Here is a picture of PS-32 into a Lionel 2-8-2. Have Tender completed, have to add smoke to engine. This is the older DCRU Lionel, so I custom build a harness using a Diesel PCB to fit in the original slot on tender. This is where the tether comes out of the engine vice tender.
Also an MTH PR 4-6-0 G5 with ERR installed. This was unique in isolating the tender shell from the frame for antenna. The rear steps are removable and a friction fit to the frame and unfortunately the shell. Besides isolation with kapton tape, nylon fittings, I had to file a gap into the steps to keep in from contacting shell at the corner.
Last is a New Atlas RS-3 converted to PS-3 Diesel. Atlas have very smooth running diesels. Sounds with the latest PS-3 RS-3 sound set are amazing. G
