S.P.A.D. (Signal Passed At Danger) Systems

Railway signalling relies heavily on track-side warning lights, however, due to speed, distractions and fatigue, these primary signals can be missed. The result can be not only damage to rolling stock, track and rail infrastructure, as well as costly disruptions to rail services, it can mean loss of life. As a supplementary solution for ensuring the primary signals are not missed, SafeZone is fast to deploy and very low cost compared to alternate treatments.

By installing SafeZone 'WiSPAD' (Wireless SPAD) beacons on the railway sleepers and linking the activation system to the rail signalling control system via a hardwired connection or a non-intrusive detection system, SafeZone delivers a solution that can be retrofitted into existing locations, or fitted as part of new works, without major additional civil works or expense. And because the beacons run right down the centre of the track, there's very little chance the warning message they deliver can be missed!

Depending on the location and the nature of the warning needed, the SafeZone beacons can be programmed to either flash in unison, or flash sequentially, creating a 'runway effect'. Lights also respond to ambient light conditions, dimming at night and become brighter during the day.
