ABSTRACT:
A rail truck for use in an elevated closed beam having a slot in the bottom surface for clearance of a car body support member. The passenger car body is hung beneath the beam and elevated above the ground with the trucks running inside the beam. The flanged wheels run on a pair of parallel rails with an electric power rail located above the center of the two running rails. The suspension permits restrained swinging of the passenger car in the lateral and longitudinal directions. A safety wheel is mounted to the frame to prevent upward movement of the frame to the extent that the wheel flanges on the running rails could climb over the top of the running rails. A pair of auxiliary climbing rails are mounted parallel to the power rail and above the running rails. Auxiliary climbing wheels on the truck are mounted on actuators which permit a controlled elevation of the auxiliary climbing wheels.
