Disclosed is a rail of a machining apparatus having a traveling carriage, wherein rail members of a rail are connected at a rail member connecting portion in series such that running surfaces of adjacent rail members are in contact with each other, wherein the rack members are arranged in series on an attachment surface of the rail member such that an interval between teeth of adjacent rack members at a rack member opposing portion at which the adjacent rack members are opposed to each other is the same as a predetermined tooth pitch of the rack members, and wherein the rack members are attached to an attachment surface of the rail member by bolts which are inserted through the elongated holes formed on the attachment surface and which are screwed into the threaded holes of the rack member.

An elevated guideway performing the function of supporting, guiding and propelling pneumatic transport vehicles for passengers and loads. The two-part elevated guideway is formed by two components, each corresponding to one side of the cross section, divided by a vertical axis passing through the center of the slot. Components are not symmetrical, the left hand component having a wider top table. Components are joined through a niche already present at the lower slabs which is filled with a structural resin. Niche for joining the two-part elevated guideway has a central type female-female fitting. The elevated guideway includes guideway guards, two additions for installing the propulsion duct slot seal, tubes for the electric power supply and telecommunication and control cables, the protective railing for protection in the side emergency gangway, the unit for securing the rail via the web thereof, rails and the third and fourth electric power supply rails of the vehicle. The two-part elevated guideway may have, combined on the same beam of the propulsion duct, a secondary propulsion duct, thereby forming a single, non-separable structure.

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 commandcontrolling 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.

A rail vehicle including a wheel assembly having wheels configured to traverse rails of a railroad track, a controller having a processor in communication with the wheel assembly, and a non-transitory computer readable medium, disposed on the vehicle, and containing instructions, which, cause the following steps in real-time as the vehicle traverses the rails: determine a rail pressure of the wheels on the rails, determine a degree of curvature of the rails as the vehicle moves along the railroad track, determine a minimum rail pressure of the wheels on the rails based on the degree of curvature, determine if the rail pressure is equal to or greater than the minimum rail pressure and adjust the rail pressure of the wheels on the rails to be the minimum rail pressure when the rail pressure is less than the minimum rail pressure to maintain stability of the vehicle on the railroad track.

An autonomous electric road vehicle is transported by a railcar for automated railed travel on a railway. During automated railed travel, the railcar is powered by the autonomous road vehicle's main power source and driven by the autonomous road vehicle's driving automation control system. A driver control of the autonomous electric road vehicle allows a human driver to apply emergency braking during both road and railed travel.

A method for tractive force distribution for a power-distributed train is provided, which includes: determining a current motor car of a target train; acquiring parameter information of the current motor car; calculating, based on the parameter information, axle load transfer at four axles of the current motor car; calculating, based on the axle load transfer at the four axles of the current motor car, current axle loads on the four axles of the current motor car; and performing, based on the current axle loads on the four axles, distribution of tractive forces of the four axles of the current motor car using an electrical control compensation technology.

A magnetic traction assembly is disclosed for a railcar mover that provides additional downforce to improve traction for a railcar mover when required. The magnetic traction assembly may comprise a frame, an actuator, and a magnetic element positioned underneath a railcar mover. The magnetic element may be lowered to a deployed position, where the magnetic element is positioned near the railroad rails such that the magnetic field from the magnetic element interacts with the railroad rail creating an attraction force that provides additional downforce to the railcar mover.

An auxiliary drive axle assembly is disclosed for a railcar mover that provides traction for a railcar mover when required. The auxiliary drive axle assembly comprises a frame, a plurality of hydraulic motors, and a plurality of wheel assemblies positioned underneath a railcar mover. The auxiliary drive axle assembly may be lowered to a use position where the wheels engage the rails either upon demand by the railcar mover operator or automatically by a control system based upon a set of monitored parameters. When in a use position, the control system directs the power to the hydraulic motors such that the wheel assemblies can have optimal traction to assist the railcar mover.
