I just bought two passenger cars that have lighted interiors. I wonder what were the colors the Uncle Pete used on the interior late 40's - early 50's. All the photos I have seen are in black and white. I bought the Bachman combine and observation car. My layout is small, 4'10" by 8'. but I have rigged it to run in moon light (blue lamp bulbs) and with all the city lights, I feel it could only add interest to see people and walls, floors and furniture in color.
