Rail track grooved rail comprises mushroom in upper part with convex running surface, groove separating flange from mushroom and base having plane support surface

摘要

The grooved rail comprises in its upper part (5), a mushroom (7) with a convex running surface having a running surface of small convexity (17). A flange (9) is separated from the mushroom by a groove (11). In the lower part is a base (1) having a plane support surface (2). The inclination ( alpha ) of running surface relative to the plane support surface corresponds to a slope of 1/20. An Independent claim is included for the use of a groove rail.
