Anti-vandal lock for rail shoe

FIELD: transportation.

SUBSTANCE: anti-vandal lock for a rail shoe comprises a body in the form of a pipe equipped with an end hole for a key at one side and a shackle in the form of a bracket. The body is equipped with a smaller bracket permanently fastened perpendicularly to the body axis with its vertical part and a larger bracket detachably fastened by a threaded tightening bolt, inserted into the body from an end along the axis. The body at one end is equipped with a head with a shaped head of the tightening bolt arranged therein, and at the opposite end - with a guide slot for the guide key of the larger bracket inserted into the body, in the horizontal part of which an axial threaded blind opening for the tightening bolt is arranged. The tightened brackets fit tightly to both cheeks of the shoe, the fixing flanges of the brackets are located at the edges of the rail head.

EFFECT: increasing the reliability of fastening the brake shoe on the rail with preventing the shoe removal.

Hump brake shoe // 2375227

FIELD: railroad transport.

SUBSTANCE: hump brake shoe comprises stop with lever and skid. Note here that aforesaid stop and skid are made from either antifriction material or somewhat other material. In the latter case wheel rolling surface has antifriction linings that, in pair with wheel material, boast low friction factor. Skid lower part has slot accommodating friction lining that, in pair with rail material, boasts low friction factor. Stop top part accommodates vessel with liquid to be fed, via wick, onto wheel rolling surface.

EFFECT: reduced wheel and hump damage, eliminated sparking.
