A bogie for a railway vehicle has at least two track guide units, in particular at least two wheels sets. A traction motor is arranged in the region of one of the track guide units, hereinafter called the first track guide unit. The traction motor drives the first track guide unit. A power converter supplies power to the traction motor driving the first track guide unit. The power converter is arranged in a region of a different track guide unit, which is not driven, i.e., the second track guide unit.

The pulling device includes at least one motor; an epicyclic (or planetary) gear train comprising a first element, a second element, and a third element selected from an internal sun gear, an external ring gear, and a planet carrier, the first element being integrally secured in rotation with the output shaft of the motor, the second element being designed to drive an axle of the vehicle in rotation; the detection means detecting an anomaly with respect to the motor; the releasable locking means, that are capable of assuming a locking configuration locking the third element in rotation, and a release configuration for releasing the third element; and the control means command—controlling the maintaining of the locking means in the locking configuration when no anomaly is detected, and moving of the locking means into the release configuration when an anomaly is detected.

Systems and methods are provided for retrofitting, or producing, a truck assembly with a traction motor to propel a rail car or other vehicle. A traction drive frame assembly is an integrated unit combining the traction motor with its transmission means, an arrangement that prevents the traction drive frame from rotating when the traction motor is powered. The traction motor can be positioned in a space between a bolster and an axle of the truck assembly, and a jackshaft assembly can be positioned outside of the space. Then, one or more gears, pulleys, chains, etc. between the traction motor and the jackshaft assembly provide mechanical advantage and amplify torque transmitted from the traction motor to the jackshaft assembly. A second operable connection between the jackshaft assembly and the axle amplifies the torque a second time such that a relatively small traction motor propels a rail car or other vehicle.

The invention relates to a bogie (10) for a high-speed railway vehicle, comprising: a bogie chassis, at least one wheel (20) mounted rotating on the chassis by means of an axle (18) and a primary suspension system (22), at least one motor (24), for each motor (24), at least one gearbox (26) able to mechanically link the motor (24) and the axle (18). Each motor (24) is rigidly fastened to the chassis (12).

A self-propelled railcar having a structure; at least one bogie attached to the structure, a sensor suite; a propulsion motor; and an energy storage system. The at least one bogie having at least one powered axle. The sensor suite has a processor and a plurality of sensors. The energy storage system includes a controller and a power source, wherein the controller provides energy from the power source to the propulsion motor to the powered axle in a predetermined manner to control movement of the self-propelled railcar. The energy storage system may be off-board.
