Abstract
A stand alone, double stack railroad well car for carrying stacked containers includes a platform suspended at each end upon swing hangers from a multiple axle truck or suspension system, utilizing leaf springs. Adjacent axles are connected by bridge beams which are pivotally connected to the leaf springs. Shear pads connected between the bridge beams and axles permit limited angular displacement of the axles relative to each other. An axle guard is provided for limiting lateral movement of the car relative to the trucks. An axle guard frame assembly is rotatably connected to the under side of the car body or platform at each end. It includes vertical axle guards which engage the axle bearing adapter housings to limit lateral movement. The rotatable connection of the axle guard frame assembly underside of the carbody to the platform permits limited rotational or pivotal movement of the axle guard frame as the suspension system negotiates a curve in the track.
