Williams F-7 Dummy Unit with LED lighting and Cab Interior Lionel K-line MTH Layouts O Scale Gauge

In this episode, I'll complete the installation of LED lighting to this Dummy Unit. I've already restored the Three Williams F-7 Shells that I purchased from EBAY. One powered frame is working like new and a dummy frame was recently brought back to life. Now it's time for a lighting update inside the Dummy Unit. Just when I was about to install new LEDs, I realized that there's plenty of room in the Dummy Unit for an interior. Now I'm off on that tangent and the lighting will eventually be installed. But first, the interior.
