Abstract: The invention provides a seal for rails in a road level railbed comprising inner and outer resiliently flexible elongate members secured about each rail. The seal members are contoured to fit snugly against the inner and outer sides of a rail and are provided with a flexible membrane accommodating rail spike heads. The inner members have a groove to allow clearance of the flange of a railcar wheel and a flexible membrane extends beneath the groove. Movement of the flexible membrane in response to the railcar wheel flange breaks up silt and detritus which has a tendency to settle and pack hard in the flange groove. The movement of the flexible membrane also allows for deicing in the winter.
