Track Warning Services

Automatic Track Warning Systems (ATWS) provides advanced warning of approaching trains to work groups operating within a Protected Area; this will be identified on the ATWS design plan. These sites are usually static and can cover several lines and junctions. The ATWS uses strike-in/strike-out treadles at specific locations on the track. An audible or visual warning is triggered when trains pass the strike-in treadle. The alarm stays on until the train passes over the strike-out treadle, cancelling it.

Track Warning System products include semi-automatic systems (SATWS), which is approved for Open Line and ALO. The intelligent design provides improved, autonomous railway alerts to your workforce. The treadle detects trains approaching, and the SATWS Controller cancels them as they clear the worksite, hence the term Semi-Automatic. The automatic announcement eliminates fatigue and personnel issues caused by the standard Lookout warning. The Semi-Automatic system’s simplicity makes it scalable and reliable for most infrastructure tasks, allowing safe and controlled access when needed. Fully radiographic SATWS capabilities minimise the need to run cables, reducing installation staff and time.

RSS Infrastructure is the leading provider of mobile lookout warning systems in the UK. Our mobile patrolling teams are suitable for transient sites requiring patrolling, surveying, and T-22 walkouts. LOWS uses a radiographic signal to warn workers about approaching trains. The LOWS controller protects the workgroup during the shift, maintaining site safety and productivity. LOWS technology can use several red zone prohibited areas, increasing customer productivity.

Our LOWS systems can deliver an audible and visible warning across a 1000m worksite. SIL4 certification increases the system’s reliability. Distributing announcement devices along the working perimeter is unobtrusive while giving a louder and better visual signal than an unassisted lookout. The device can be used as a visual warning during night-time work and in section 61 noise abatement areas. Many of our clients use LOWS with site warden warning to ensure worker safety.

RSS Infrastructure has also invested significantly in the ZKL 3000 RC, which is designed to protect track workers without transferring risk. This ground-breaking Additional Protection unit has the technology to protect those working in line blockages while gathering data for the first time, with exceptional measurement and analytics.

Define safe and unsafe zones, site entrances, equipment locations, and more with geofences so everyone can safely navigate the area. Your teams put on their wearable technology without onsite setup or additional infrastructure. Wearables are updated automatically and in real-time, keeping your teams updated about changes to safe working zones. Crossing a geofence zone boundary activates audible, visual, and vibration alarms. Real-time notifications notify people of potentially dangerous situations, restoring situational awareness.

Our planning team conducts site surveys and safe work planning to protect track employees and minimise the risk of incidents. The team has experience establishing safe work plans for various worksites and frequently communicates with clients to ensure worker safety.
