Abstract
Insulators which lie between the rail and elastic rail fasteners are correctly positioned on either side of the rail by manipulating the rail by the application of a pulsed force to either side of the rail. A pair of hydraulic rams 19, 20 driven by the same pressure pump are used to drive two pulse heads 9, 10 via pivoted linkages to abut either side of the web 3 of a rail 1. The pulsating operation is carried out prior to the operation of the clip fitting machine to ensure that the rail insulators are in the correct initial position prior to being driven on to the rail flange.
