ABSTRACT:
A railway track in which a rail is supported within a groove of a rail bed. The groove has outwardly sloping shoulders each spaced from the sides of the rail. Continuous clamps extend along each side of the rail. The clamps are secured by spaced apart hold-down assemblies positioned vertically between the clamps and the respective sloping shoulders to secure the track against both vertical and lateral movement. Elastic material pads completely isolate a rail from both the bed and the clamps.
