ABSTRACT:
A railroad rail support system is provided which utilizes tire carcasses filled with annular concrete cores. Railroad rails are attached to the concrete tire carcasses by means of load distribution plates anchored to the concrete cores and hold-down clips which are attached to the load distribution plates and retain the rail flanges against lateral and excessive vertical displacement with respect to the load distribution plates. Gage bars may extend between opposed pairs of ties and be anchored in the concrete cores to retain proper gage spacing of the rails.
