The Lionel 3435 Operating Traveling Aquarium Car from 1959-62. It is a postwar classic. As it moves down the track the fish appear to swim around in the tank. Actually the fish are printed on a clear filmstrip attached to a vibrator motor, and the glass on the side of the car is rippled along with the illimination behind it that creates a real neat effect. The car also features interior illumination, plastic trucks, operating knuckle couplers, metal wheels and axles.
