摘要：
A boltless two-piece rail fastening assembly for securing a railway rail, supported on a conventional tie plate, to a wooden cross tie is comprised of a chair and a rail clip latched thereon. The chair includes a body, having a jaw with a bight configured to receive the clip, and at least one downwardly projecting leg or shank for securing the chair adjacent the base flange of the rail. The rail clip is a torsional spring clip in the general form of an "S" having a rail-bearing leg for proximate engagement with the base flange of the rail and a tie bearing leg for proximate engagement with the tie plate.
