A manufacturing method and a manufacturing apparatus for a head hardened rail to which various alloy elements are added and which is excellent in hardness and toughness of a head portion surface layer. The method includes, when forcibly cooling at least a head portion of a hot-rolled rail or a heated rail, starting the forcible cooling from a state where a surface temperature of the head portion of the rail is not less than an austenite range temperature, and performing the forcible cooling at a cooling rate of 10 C./sec or more until the surface temperature reaches 500 C. or more and 700 C. or less after the forcible cooling is started.

An apparatus for harnessing energy from a wheel travelling on a railroad track includes an elongate body with a plurality of pockets spaced apart along a top surface thereof. Energy collection devices are installed in the pockets, and each includes an actuator extending proud of the top surface. A mounting assembly releasably mounts the body adjacent to the railroad track so that the actuators of the energy collection devices are positioned in a path of the wheel to be actuated thereby. The energy collection devices may be coupled to a low pressure fluid supply reservoir and a high pressure fluid accumulator, and used to pump fluid from the reservoir to the accumulator upon actuation.

The present disclosure discloses a rail vehicle. The rail vehicle includes: a plurality of bogies, where the bogie has a straddle recess suitable for straddling a rail; and a vehicle body, where the vehicle body is connected to the plurality of bogies and pulled by the plurality of bogies to travel along the rail, and the vehicle body includes a plurality of compartments hinged sequentially along a length direction of the rail; the plurality of compartments forms at least one compartment group, the compartment group includes three compartments hinged sequentially, and the bottom of each of only compartments that are located at two ends of the compartment group and that are of the three compartments is connected to the bogie; and in the length direction of the rail, a surface that is of a compartment at at least one end of the vehicle body and that faces away from an adjacent compartment is provided with an escape door that can be opened and closed. The rail vehicle according to this embodiment of the present disclosure facilitates optimization of the structure of an escape passage, reduction in occupied space and the weight borne by the rail, and improvement in stability, and is flexible in steering and low in costs.

A profile for the composition of a railroad rail with the provision for at least one pair of webs in each profile of the rail, in addition to being provided with a set of cutouts of a plurality of geometric shapes that allow the crossing of wires and cables for several purposes. The webs arranged more laterally to the center of the rail provide greater stability to the rail the plurality of holes enables greater capacity to absorb stresses and vibrations, consequently, greater stability for the train, especially at high speeds. The adopted geometries also present a greater mechanical strength in relation to common rail profiles compared to the same amount of used material.
