Used a plastic ice tea jug, like a milk jug, but it had tea in in instead of milk. LOL
I couldn't get enough flat surface to cover the windows in the doors. I will glue pieces of plastic over the doors and the rear window in the observation.
I cheated and used LED tea candles to light the cars. I usually don't care for lighted cars so these will work for the odd times I want lights. The flickering golden light kind of mimics old school track powered lights too.
