A vehicle, in particular a rail vehicle, includes a compressed-air-operated toilet device and a compressed air supply system which supplies compressed air to the toilet device during normal operation. The vehicle also includes an emergency compressed air source that is suitable for providing compressed air for continued operation of the toilet device in the event of a failure of the compressed air supply system.

An external runflat apparatus for a guide wheel system of a monorail transport system. The external runflat apparatus includes a hub member and a tread member. The tread member is connected to the hub member and includes a base member and a covering over the base member.

Disclosed is a telescopic type collision energy absorption device for a rail vehicle, which includes two sets of mechanisms functioned individually. The two sets of mechanisms are mounted respectively on either side of end portion of the vehicle. Each set of the mechanism includes an anti-climber, an energy absorption circular tube, pull rings, cutters, cutter fixing blocks, a mounting base, a cutter base, a guide cartridge, a double-acting type air cylinder, a base, bolts, torsional springs, pins, locating slots, a double-acting type solenoid valve, a controller and air storage tank. When the energy absorption device is in a non-operating state, the double-acting type air cylinder is in a state of tension where it pulls the energy absorption circular tube in such a way that the energy absorption circular tube is retracted into the interior of the guide cartridge, the cutters are pressed against the outer wall of the energy absorption circular tube. Before a collision of the vehicle, the double-acting type air cylinder under the effect of the high-pressure air pushes the second tube in such a way that the second tube is ejected outwards, the cutters are pressed against the locating slots of the energy absorption circular tube under the effect of spring force. The cutters cut the energy absorption structure and absorb the energy when the energy absorption circular tube is subjected to an external force and retracts towards the interior of the guide cartridge.

An elastomeric element for mounting a current collection device includes an inner hub member; an outer ring defining an exterior annular surface of the elastomeric element; and an intermediate ring of elastomeric material disposed between the inner hub member and the outer ring. The outer ring includes a plurality of segments individually connected to the intermediate ring and wherein the outer ring comprises at least one locking feature configured to be engaged to prevent rotation of the elastomeric element within a housing.

A block, towing system, and a method for towing rail cars is provided. The block includes a first channel, a second channel, a third channel and a fourth channel. The first channel is located on a first side of the block. The second channel is located adjacent to the first channel on the first side of the block. The third channel is located on an opposite side of the block from the first channel. The fourth channel is located adjacent to the third channel on the opposite side of the block from the second channel.

A shelving block comprises a first and second shelving units facing from opposite sides of an aisle. The first shelving unit defines a first crate storage location and a second crate storage location that different in height. The first crate storage location is accessible to a robot between a pair of neighboring horizontal rails having a first vertical spacing between them defining a height of the first crate storage location. The second crate storage location is accessible to the robot between another pair of neighboring horizontal rails having a second vertical spacing between them defining a height of the second crate storage location. The first vertical spacing is larger than the second vertical spacing. The robot carries crates according to instructions from a computerized control.

A rail maintenance vehicle includes a frame, a workhead, an actuator, a pilot valve, and a throttling valve. The frame includes wheels that travel along rails. The actuator extends and retracts the workhead with respect to the frame. The pilot valve receives a fluid and controls the flow of the fluid to at least one output. The throttling valve adjusts a pressure of the fluid at an output relative to a pressure of the fluid at an input. The pilot valve and the throttle valve are coupled such that the fluid travels through the pilot valve and the throttling valve to cause the workhead to be extended or retracted.
