Abstract: A method for coating a surface of a track component with a coating containing aluminum by means of an arc spraying process. In order to form a coating that exhibits a high resistance to sliding and abrasive wear, aluminum and silicon are applied to the surface in a ratio of 3:2 ?Al:Si?4:1 by an arc spraying process.

Abstract: This invention provides a fencing system (10) comprising a plurality of spaced apart parallel extending upright posts (12); a plurality of horizontally extending bearers (14); and a plurality of parallel extending uprights (16). First connecting means (18) connects the bearers (14) to the posts (12) and second connecting means (20) connects the uprights (16) to the bearers (14). Each post (12) defines an elongate channel 12.1, and is provided with a cover 12.2 connected to the post (12) by a fourth connecting means (22), for closing the channel 12.1. Posts (12) located in a central region of the fencing system (10) are adapted to receive a supporting insulator (24), for supporting an electrified conductor (26). A carrier (28) is connected to corner posts (12) by third connecting means and includes a carrier (28) with connecting formations 28.2 for connecting to an insulator (30) for carrying electrified conductors (26).

Abstract: The invention relates to a high-strength steel track element, and process of making the steel track element by rolling and heat treating. The steel comprises: 0.3-0.6% C, 0.8-1.5% Si, 0.7-1.0% Mn, 0.9-1.4% Cr, 0.6-1.0% Mo, balance iron and smelting-related impurities. The steel has a bainitic basic structure, a tensile strength of at least 1600 N/mm2 and a technical yield strength of at least 1250 N/mm2.

Abstract: A process for manufacture of a railroad track part, in particular a large points part, with rail parts such as a frog point and connecting rails, and the track part obtained. The track part is made of materials of differing composition, one of which is a carbon steel and one of which is an austenitic manganese steel, which are connected by welding and are subsequently subjected to a joint heat treatment. To permit joining of the materials without negative effects on their properties, the parts are joined directly by electron beam welding or indirectly via an intermediate layer comprising a nickel-based alloy, the joined parts then being heated to a temperature T and held over a time t such that for the austenitic manganese steel, solution annealing takes place, and for the carbon steel, austenitizing takes place.
