I've had the "dementors coach" but could not figure out how to get inside. Lionel instructions are worthless. You need to very carefully open a gap between the roof and the car body. I wound up using a Tamiya paint stirrer to get started and a 1 foot steel ruler to finish the job.

This is looking down into the car to show the three light bulbs that have been painted with red, green, and blue clear paint to make simulated wand flashes. Each bulb has one side coated with one color.

I've tested the colors with the roof off and I will re-assemble and take additional pictures showing the effect. I've left the roof off to take additional measurements to see if it's possible to make car interiors for the rest of the set. Right off the bat I will have to remove the bulb sockets and replace them with over head "streamline" surface mount LED's. I'll probably wind up using 3 ply model plane plywood and bass wood to make the carriage interiors.
