HOW DOES HPSS INTERFACE WITH THE S&C PANEL?
Dependent upon rail standard, the Hollow Bearers of the HPSS have appropriate Slide Plates with the usual proprietary Stock Rail attachment (e.g. Schweihag, Vossloh, Pandrol). Toe Detectors are attached directly to the Stock Rail via a clamp arrangement (2 bolts) requiring no Stock Rail drillings. All Switch Rail interfaces are via drilled pairs of holes, through the web, for the location of supplied bolt-on brackets. The standard universal drillings at the toe are utilised. Each location of the Back-Drive and Supplementary Detection Stretcher Bars require a pair of holes in each Switch Rail for its attachment. No other attachments or drilling of the rail foot is necessary. There are therefore only 2 bolts per side at each hollow bearer location. All electrical connections are by the supplied approved pre-wired connectors. The torsion drive bar drops directly into its drive pins within each bearer and is held by the insertion of a single bolt at each clamp.
