Wavetrain LX Protection

The Wavetrain Level Crossing Protection (WLXP) is an end-to-end SIL 2 certified product that detects approaching trains using SIL 4 certified acoustic sensors. The acoustic sensors are mounted on the rails and listen for the distinct sound waves generated by approaching trains. The digital data is analysed by a nearby Control Unit, which activates the customer’s preferred warning devices at the appropriate time.

All components of the WLXP are installed at the the level crossing site, thereby reducing cabling compared to competing systems. This makes the WLXP quick to install and easy to maintain, all at a minimal life-cycle cost.
