I could use a little advice. I'm scratch building the first (of many) 1880s On3 passenger cars. O scale cars look bad without interiors...so I'm going to want to light up the interiors...realistically...which probably means oil lamps in the clerestory. (for non-1860 to 1960 modelers...the raised center roof...I'm also guessing oil lamps as the gas lamps were not really feasible except in the New York area where the fuel factory was located) Therefore, as I've just about finished the outer sheathing/windows of the car...I need to consider how to light them. What lighting methods have you heard of to represent oil lamps? This would be a similar color to 19th century headlights. I also need them to be small. I don't view the lights being in the clerestory as essential...so long as the car is illuminated with adequate illusion to appear as if it could be. The other key ingredient is DCC. Has anyone wired passenger cars to be equipped with on/off lights just like engines? I'd love to incorporate such an accessory decoder...so I need to plan the wiring layout now...before I begin gluing the wall assemblies together. Here's the car's thread...http://forum.zealot.com/t153242/ I can also promise a future thread about scratch building the trucks...I've been performing research and I've been testing my construction methods on a prototype freight truck. Thank you.
