摘要： In a railway sleeper assembly, a pair of rail insulators (3) designed for use with a steel railway sleeper (1) which includes at the opposite sides of each intended rail location thereon a pair of openings (6) for receiving the respective stems (8) of a pair of shoulders (4), are each operatively disposed, when in use, between a foot of the rail (2) and the respective proximate shoulder (4). Each insulator (3) includes a member (11) which, when the insulator is in use, operatively extends below a top surface of the sleeper (1) and into the associated opening (6) so as to lie between the walls of that opening (6) and the stem (8) of the associated shoulder (4), thereby to retain the shoulder (4) in its operative position relative to the sleeper. The insulators (3), the shoulders (4) and a pair of rail clips (5) are preloaded onto, and are preassembled with, the sleeper (1) at a location remote from the track site, such that the entire assembly, with the rail clips (5) mounted in a preload position on the shoulders (4), can then be transported as a unit to the track site while the various components are retained on the sleeper (1) in their operative positions and are secure against falling off the sleeper (1) during transit of the assembly to the track site.
