Resiliently mounted rail for rail vehicles

A rail assembly for a rail-vehicle track, comprising:

• a rail having:
• a rail head,
• a base, and
• a shank connecting said head with said base and having a pair of outwardly facing downwardly and inwardly tapering flank shank surfaces;
• a frame flanking said rail and having a pair of downwardly tapering members forming a pair of inwardly facing flank frame surfaces spaced from and juxtaposed with the outwardly facing flank shank surfaces of said rail, said frame forming a base spaced below said base of said rail;
• and
• elastic intermediate layers disposed between the juxtaposed surfaces of said rail and said frame and prestressed between them with a spring constant from 2 KN/mm to 8 KN/mm per meter of rail length,
• the flank shank surfaces having:
• upper downwardly and inwardly tapering rectilinear portions, and
• lower downwardly and inwardly tapering rectilinear portions, said lower and upper rectilinear downwardly tapering portions angularly adjoining each other and forming different angles with a vertical,
• at upper ends of said upper rectilinear portions, upwardly and outwardly turned head surfaces being connected to said upper rectilinear portions, delimiting said head and defining steps between said head and said shank,
• the frame surfaces being rectilinear and of a single angle with a vertical over a height thereof juxtaposed with the shank surfaces.
