Summary:The invention relates to a profiled rail (1), especially for a railway track , with a reduced total radiated noise level when in use. In order to reduce th e noise radiation level, at least one web side surface (31) is substantially concavely rounded without any salient points in the lower region (31') betwe en the transition edge (32) on the side of the rail patten (3) and the centre o f gravity axis (X) in the rail cross-section and/or the height (H) of the pattern is increased by comparison with a normally profiled rail having a corresponding total rail height A. The invention relates to a profiled rail (1), especially for a railway track, with a reduced total radiated noise level when in use. In order to reduce the noise radiation level, at least one web side surface (31) is substantially concavely rounded without any salient points in the lower region (31') between the transition edge (32) on the side of the rail patten (3) and the centre of gravity axis (X) in the rail cross-section and/or the height (H) of the pattern is increased by comparison with a normally profiled rail having a corresponding total rail height A.
