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