A railroad car truck including a first side frame, a second side frame, a bolster, and a first plurality of warp restraints, each first warp restraint configured to prevent warping of the bolster relative to the side frames. Various embodiments include opposing bearings of each warp restraint that engage each other.

The electric vehicle can include: a payload interface, a payload suspension, a chassis, a set of bumpers, a sensor suite, a controller, a chassis suspension, and an electric powertrain. The electric vehicle 100 can optionally include a payload adapter, a power source, a cooling subsystem, and/or any other suitable components. The electric vehicle functions to structurally support a payload, such as a cargo container (e.g., intermodal container, ISO container, etc.), and/or to facilitate transportation of a payload via railway infrastructure.

Vehicles for use on a railway and their methods of operation are disclosed. In one embodiment, a vehicle includes a bogie with wheels engaged with opposing tracks extending along a length of a railway the bogie travels along. The vehicle includes at least one sensor configured to sense a position of the bogie and/or wheels relative to the tracks of the railway. A processor of the vehicle uses the sensed position of the bogie and/or wheels relative to the tracks to steer the wheels of the bogie along a desired path on the tracks as the bogie travels along the railway.

A method for reducing slack in a linkage chain of a vehicle truck assembly is provided. In one example, the method includes responding to a request to de-lift a lift mechanism by reducing pressure in an actuator coupled to the lift mechanism, where the lift mechanism is configured to transfer a load from a first axle to a second axle of the vehicle during the de-lift, and during the de-lift, maintaining the pressure in the actuator at or above a threshold pressure to maintain tension in a weight transfer device of the lift mechanism

The invention concerns a vehicle guided on a railway track comprising a chassis and at least one wheel assembly interconnected to the chassis and a method for steering said vehicle. The wheel assembly comprises a cross-member having a first end to which a first hub is interconnected by a first steering joint and a second end to which a second hub is interconnected by a second steering joint. A first wheel is attached to the first hub rotatable around a first rotation axis and a second wheel is attached to the second hub rotatable around a second rotation axis. A first sensor determines the lateral position of the first sensor with respect to the rail. The first sensor is attached to the first hub and is, with respect to a direction of travel, arranged in front of the supporting area of the first wheel in a horizontal direction spaced a distance A1 apart. The first sensor is interconnected to an actuator by a control unit which calculates a steering angle for the at least one interconnected wheel depending on the determined position of the first sensor.

An embodiment of an electric vehicle drive apparatus includes a rotary electric motor, an electromagnet apparatus, an electric motor controller, and an electromagnet controller. The rotary electric motor drives at least one wheel. The electromagnet controller generates at least one of an attraction force between a rail and a bogie, and a propulsion force. The electromagnet controller controls the electromagnet apparatus. The rotary electric motor and the electromagnet apparatus are provided on the same bogie.

The electric vehicle can include: a payload interface, a payload suspension, a chassis, a set of bumpers, a sensor suite, a controller, a chassis suspension, and an electric powertrain. The electric vehicle 100 can optionally include a payload adapter, a power source, a cooling subsystem, and/or any other suitable components. The electric vehicle functions to structurally support a payload, such as a cargo container (e.g., intermodal container, ISO container, etc.), and/or to facilitate transportation of a payload via railway infrastructure.
