In accordance with an embodiment, there is disclosed a rail cover for covering an underside of a foot of a railway rail, the rail cover comprising: mutually connectable cover parts configured to respectively extend at least partially around opposing sides of the foot of the railway rail and connectable by an adjustable ratcheting connection or an interference fit to resist separation of the mutually connectable cover parts

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 invention relates to a device for fastening trackside modules to a rail having a base and a head. The device includes two clamps that are clamped on the base of the rail with the use of a mechanism that extends under the base of the rail. At least one of the clamps is movable. A bracket is fastened to at least one of the clamps and a trackside module is fastened next to the head of the rail. A pair of brackets is fastened with the use of fasteners to surfaces of each of the clamps. The brackets extend transversely to the longitudinal axis of the rail and at least one upwardly extending section is fastened using second fasteners to at least one of the brackets outer side surfaces. At least one trackside module is fastened to an upper end region of at least one upwardly extending section.
