Tongue rail
The invention relates to a tongue rail (1) for use in points, comprising a rail head (5), a rail web (6) and a rail base (7), wherein the tongue rail (1) has a first long section provided for abutting a stock rail (2) and a second, long section lying outside the abutting region, wherein the tongue rail (1) has in the second long section a basic cross-section profile, wherein in the second long section a vertically running central axis is defined in cross-section through the middle of the rail head (5), and a first section (10) of the rail base (7) is arranged on a first side of the central axis and a second section (11) of the rail base (7) is arranged on a second side of the central axis opposite the first side, wherein the width of the first section (10) of the rail base (7) is greater in cross-section than the width of the second section (11) of the rail base (7), and wherein the cross-section of the tongue rail (1) has, at at least one point along the longitudinal extent of the rail, a ratio between the vertical area moment of inertia I y and the horizontal area moment of inertia I x of more than 0.5, preferably more than 0.6, particularly preferably more than 0.7.
