A rail brake element, in particular in connection with rail brake buffer blocks, com- prising a pair of clamping plates C-shaped in cross section and having upper and lower leg portions, the clamping plates engaging a rail head on opposite sides, at least one braking block element having a flat lower surface which engages th e top surface of the rail head and two upper roof like tapered surfaces, the upper leg por- tions of the clamping plates engaging the associated tapered surfaces, the lower leg portions having at the side facing the rail head a brake lining in engagemen t with the lower surfaces of the rail head, and at least one clamping bolt by which the clamping plates can be pressed towards each other, whereby the block element and the brake linings are pressed against the rail head, characterized in that the tapered surfaces of the block element have an angle relative to a horizontal plane of at least 20.degree. and the block element and the clamping plates are dimensioned such that the end of t he upper leg portions of the clamping plates have a significant distance from t he upper edge of the associated tapered surface if the rail head is not worn. |
