ACTIA’S NEW PORTABLE RADIO WARNING DEVICE (DAPR) GOES THE DISTANCE

The first real-life applications of ACTIA’s new long-distance Portable Radio Warning Device (DAPR) are conclusive. The system is being deployed on several large-scale railway renovation worksites by FVF and SAGES-RAIL, TSO subsidiaries of the NGE Group, which provides trackside safety for the SNCF railway network.

ACTIA’S NEW PORTABLE RADIO WARNING DEVICE (DAPR) GOES THE DISTANCE

ACTIA’s SAFeasy 200 DAPR system is one of the first on the market to cover very long distances: over 1 km. It is reliable and easy to install, making it possible to reconcile the objective of staff safety with continuity of service, as staff work adjacent to an in-service railway track.

The most common worksites where the ACTIA solution is implemented are designated as industrial by SNCF Réseau. These are sites where rails are renewed on an industrial scale using the BOA track renewal train. This famous ‘factory’ train unloads rails that are 80 to 120 metres in length and have come straight from the steelworks, welds them electrically on the track, substitutes them for the old rails and finally reloads the replaced rails.

This is the case in Venarey-les-Laumes (Côte-d’Or), on the Paris-Lyon high-speed line. The ACTIA system was extensively deployed on this worksite where the track was renewed by the BOA train. The system, which FVF describes as ‘extraordinary’, consists of 28 audible alarms and visual warnings, in addition to the central warning unit and the warning boxes, covering more than 1,800 linear metres. The warning point (POA) is located 890 metres away and the warning covers an area of exactly 1,760 metres. A distance that had never before been covered by a safety radio system.

The radio coverage of SAFeasy 200 is a real technological achievement in the field of trackside warning systems. ACTIA Telecom, the Telecommunications Division of the ACTIA Group, based in Millau, draws on over 30 years of expertise in radio frequency systems to develop products, systems and services in train-to-ground transmission. The company, which in the past developed a range of transmitters for digital terrestrial television, now offers innovative solutions to meet the requirements and needs of the railway market.

ACTIA’s DAPR is the safety solution of the future for railway construction sites. This is because ACTIA Telecom, through its constant pursuit for innovation, is conducting developments aimed at improving its solution, including more automation: a warning system with automatic release of the warning area and a warning solution with on-board horns in the train in order to optimise mobile worksites and deliver safety warnings as the worksite progresses.
