These new operating action and aquarium cars take their inspiration from popular O gauge cars issued in the 1950's. There were in fact a number of prototype cars built to carry live fish, perhaps the most famous being the Nautilus owned by Chicago's John G. Shedd Aquarium but of course none had glass sides! Our new Operating Action cars feature backlit scenes that move as the car rolls by, with aquatic-themed cars featuring wavy glass to simulate water.

This exciting car not only features a backlighted moving animation strip visible through each of the car's four large viewing windows, but is decorated with iconic M&M's characters, creating a whimsical and fun addition to any model railroad.
