ACTIA Telecom, the ACTIA Group’s telecommunications division, is deploying its wireless trackside safety warning system on several railway track work sites on France’s railway network. This second-generation radio warning system is one of the first in the market to cover a work site over 1 km long.
The system ensures the safety of track maintenance and service personnel. It is flexible and easily installed, meaning that it can be quickly deployed on work sites. These features have won over warning service providers as well as the French railway operator, SNCF, which is conducting a major maintenance and modernisation programme on the French railway network.
HOW DOES IT WORK?
The SAFeasy 200 wireless trackside safety warning system consists of:
- – a central warning unit (CA) for the head security officer,
- – two warning boxes (BA), automatic or manual,
- – a succession of audible and visual warning devices (ASL), on tripods or on the ground,
- – a range of accessories for using the system in a number of configurations.
The SAFeasy 200 warning system alerts personnel working close to the railway track when trains are approaching. In manual configuration, the watchman uses their portable warning box to announce one or more train movements towards the work area. This triggers the audible and visual warning via the radio link on all the audible and visual warning devices in the work site. Once the train has left the work site, the Personnel Safety Officer (ASP) resets the system manually via the central warning unit.
ENHANCED RADIO PERFORMANCE
The radio coverage ensures very good availability on work sites covering long distances.
The digital radio system integrates a space-diversity reception solution in the form of two antennas. The robust radio transmission covers distances of 1 to 2 km between the warning point and the central unit. The chosen technology is suitable for multipath propagation. It is ideal for work sites in wooded areas, or with bends and obstacles (engineering structures, bridges, walls, vegetation, etc.).
Finally, the fully wireless system makes the installation and operation of the trackside safety system easier and highly reliable. It thus avoids the risk of any wire breakages and loose connections during the work.
“The portable radio warning device (DAPR) is a major breakthrough in the field of railway safety. It provides enhanced reliability and safety, while reducing costs for the customer. In addition, it offers career development opportunities for operators. Customers in France have strong expectations regarding the development of this technique. ACTIA’s SAFeasy solution delivers high reliability at low costs. Our feedback is also very positive on ACTIA Telecom for the high-quality, responsive support it provides during the implementation of this solution.”
