[origin: US5645216A] PCT No. PCT/EP93/02658 Sec. 371 Date Mar. 31, 1995 Sec. 102(e) Date Mar. 31, 1995 PCT Filed Sep. 30, 1993 PCT Pub. No. WO94/08093 PCT Pub. Date Apr. 14, 1994A bearing system for a part of a railroad track, such as a rail-fastening or ribbed slab (10), supported by elastic elements on, for example, a railroad sleeper. The elastic elements form a spring system with a kinked characteristic curve such that when the spring system is subjected to force that is smaller than the forces active in the operative range (16) of the spring system, the characteristic curve rises steeply and, in the operative range (16), runs flat.
