摘要:
In a switch including a switch frog (1) with a movable frog point (2) and wing rails (5, 6), wherein the wing rails (5, 6) in the region of the frog point (2) each have a rail profile which is lower than that of a standard rail, the wing rails (5, 6) are designed as Vignol rails whose region configured with a lower rail profile is produced by metal-forming departing from the Vignol rail profile.
摘要:
In a method for connecting switch or crossing parts made of austenitic manganese steel casting, or austenitic manganese steel rails, with rails of carbon steel, the parts to be connected, optionally upon interposition of an intermediate piece, are connected by friction welding, wherein the weld with the austenitic manganese steel is cooled at static air without heat treatment.
