Title: Sound insulating railway rail underlay - has insulation units matching trapezium shaped deformation in interfacing base and support plates
Inventor: UDERSTAEDT DIETHER
IPC: E01B1/00
Filed: 1978-04-20
Abstract: Insulating elements, elastically deformable by vertically acting forces, are set between a base plate and rail support plate, in the noise-insulating railway track rail underlay. There are mutually complementary deformations in the butting surfaces(6, 8) of the base plate(3) and rail support plate(4). The insulating elements(5) are shaped to fit them. The base plate may have a trapezoid-sectioned widened piece, and the support plate a complementary recess. This system prevents unacceptable rail deviations in the horizontal line, especially crossways, virtually irrespective of insulating element thickness.
