Abstract

German Federal Railway (DB) have equipped their new high-speed lines with an overhead catenary system called Re 250 and designed it for the higher speeds and electric currents envisaged. Components made of aluminium alloys were developed and used for this new catenary type. The authors report on the selection of suitable casting and wrought alloys, as well as on design and tests of the components and on operational experience. The use of aluminium alloys together with bolts and nuts made of stainless steel resulted in a catenary system which requires only very little maintenance and does not necessitate investments higher than in case of a design based on conventional material.
