A weight shifting mechanism for a bogie frame is provided. The weight shifting mechanism may include an axle support pivotally coupled to the idler axle, a pusher link pivotally coupled to the axle support and forming a first fulcrum with the bogie frame, a support member pivotally coupled to the pusher link and the axle support, and an actuator mounted on the support member and actuatably coupled to the axle support via a live lever and a connector link. The live lever may form a second fulcrum with the support member and may be pivotally coupled to the connector link. The connector link may be pivotally coupled to the axle support. The actuator may selectively pivot the live lever about the second fulcrum to pivot the axle support about the idler axle and move the bogie frame relative to the idler axle.

A device for damping vibrations between a pair of sub-structural components of a carbody in a locomotive is provided. The sub-structural components are supported on a single undercarriage frame. The device includes a first support bracket affixed to a first sub-structural component, and a second support bracket that is interleaved with the first support bracket and affixed to a second sub-structural component. The device further includes a first stiffening element and a second stiffening element that are disposed on the first support bracket and in opposing relation to each other. The device further includes a reciprocating member that is rigidly connected to the second support bracket. The reciprocating member is movable between the first stiffening element and the second stiffening element to abut against one of the first stiffening element and the second stiffening element in response to a relative movement between the pair of sub-structural components of the carbody.

A moveable plow for a locomotive suitable for operating in sandy environments is provided. The moveable plow comprises a body and a wearable lip. The body forms a curl at its top edge along substantially the entire body width to channel the flow of sand outwardly. The lip is removably affixed to the body and contacts a rail. The moveable plow is attached to a bogie by a pneumatically operated height adjusting mechanism that can raise or lower the moveable plow. The moveable plow and rail define a sweep angle equal to or greater than an angle of repose of the sand in the surrounding environment.

A self-steering system for a radial bogie of a railroad vehicle is provided. The self-steering system includes a plurality of links which connect the leading and trailing wheelsets to the bogie frame. Each of the links is adapted to provide a smaller degree of movement between the link and the wheelset at one end and a larger degree of movement between the link and the bogie frame at the other end.
