John W. Mospan - Pittsburgh PA

Assignee:

Portec Rail Products, Inc. - Pittsburgh PA

International Classification:

E01B 312

US Classification:

238288

Abstract:

A T-shaped electrically insulated member for securing to rails having electric current passing therethrough. The electrically insulated rail member includes a metallic core and an electrically insulating material encasing the metallic core. The electrically insulated rail member can be used as a gauge plate or a switch plate. Bushings are received by the electrically insulated rail member for receipt of fasteners secured to adjacent rail members. Also disclosed is a method for manufacturing the electrically insulated rail member.

International Classification:

B61K 3/00

Abstract:

A top of rail (TOR) applicator has a bar positioned in a housing and an exit orifice on the upper portion of the bar for delivering a friction control composition to the crown of a railhead. The upper portion of the bar slopes away from the friction control composition exit orifices. The bar may be composed of an elastomer such as polyurethane. Passageway extend from an inlet or entry orifice to the exit orifices. The friction reduction composition is pumped into the entry orifice, through the passageways to the exit orifices and then onto the crown of the railhead. The friction reduction composition may be thixotropic.
