Abstract: An installation for the animation of pictures for transportation systems, such as, for example, a railway system wherein a passenger vehicle moves through an unlighted area such as a tunnel. The installation comprises a series of pictures that are mounted along the side wall of the tunnel at regular intervals and at least one light-flash emitting device, the device being mounted on the passenger vehicle and directed toward the pictures. Electric circuitry causes the flash to be emitted each time the vehicle has covered a distance equal to the space between two successive pictures. The installation provides passengers riding the transportation system with animated pictures during the course of their journey.
