I have been trying to find a project for an old 5 volt F-3 in my spare parts box, and after stumbling across an old Santa Fe passenger car set that the name and number boards had fallen off of due to what I can only assume was defective glue, an idea formed to make a passenger set out of them for my Sleepy Hollow Railway.
The passenger cars only required repainting and decaling the name and number boards, and then reattaching them with CA adhesive. The F-3 had been a retro New Haven paint scheme that required extensive sanding and repainting.
To finish up the project I added custom LED lighting boards to the passenger cars, and of course I could not resist the temptation to make one of the cars haunted, by adding skeleton figures painted with glow in the dark paint, and UV leds in the lighting board.
