Treadle Switches

To provide a safe operational environment throughout the rail infrastructure it is imperative to have a method of detecting train movements and providing signalling control.

Henry Williams are the supplier of the ‘Treadle Switch’ commonly used to initiate control primarily for Level Crossings, signal control, axle counting, depot protection and train wash systems.

The treadle switch provides detection at a given point the passage of a train or single vehicle travelling at speeds up to 260 km/hour with either uni- or bi-directional control.

Henry Williams after-sales service care is available to extend the life and maintain the high reliability of the treadle switch by refurbishing existing units and replacing all wearing components at a fraction of the new unit cost.
