摘要:
A compact, low profile, boltless, two piece railway rail fastening assembly for secring a railway to a conventional tie plate having spike holes enabling the tie plate to be affixed to a wooden cross tie. The assembly includes a drive-on, generally platelike, rail engaging, resilient, metal fastening clip coacting with a shoulder having a pair of anchor legs adapted for insertion through a pair of spike holes proximate the rail base flange so as to anchor the shoulder to the tie plate. The shoulder and rail clip cooperate to provide a positive interlocking relation which retains the clip against the rail base flange and secures the rail against movement under load.
