In an arrangement for laying rail in a railroad track over which railway cars travel, the rails (1) include a lower base flange (1a) and an upper rail head (1b). A molded elastic bearing part (5) is positioned between the lower support member (4) and an upper support plate (3). The elastic part (5) has at least two elements each inclined in the same direction but at different angles to the plane of the track. Extensions of the elements have a common intersection (S) located above the rail flange (1a) on an outer side of the track. As a result, when a load is applied to the track, a circular pivoting motion of the rail takes place about the common intersection (S). Due to the circular pivoting motion the rail head (1d) moves essentially only in the vertical direction, whereby gauge widening does not occur in the rail track when railway cars travel over curved sections of the track.

An arrangement for laying a rail in a railroad track used for supporting railway cars, the railroad track having a generally horizontal plane over which the railway cars travel, comprising a rail (1) having a long axis, a rail flange (1a) forming a rail base and a rail head (1b) spaced upwardly from the rail flange, said rail extending generally horizontally, a generally horizontally arranged bearing member (4) for bearing on a sub-soil base, a generally horizontally arranged elastic support member (5, 9) located between said bearing member (4) and said rail flange (1a) wherein the improvement comprises that said elastic support member (5,9) includes at least two generally upwardly extending laterally spaced elements each inclined at a different angle to the railroad track plane, extensions of said elements extend to a common intersection (S), and the angles of said elements being different in a plane perpendicular to the long axis of said rail of the railroad track plane and the common intersection (S) located above the rail flange on an outer side of the railroad track.
