IoT Automates Rail Brake Testing for Logistics Firm
CFL Multimodal is piloting a 20-freight-car system that uses a mesh radio network system from Traxens to capture and transmit data about the functionality of car brakes, thereby preventing potential accidents and making testing more efficient for vehicles traveling across Europe or into China.
Jul 08, 2019—
European logistics company CFL Multimodal has deployed a system using Internet of Things (IoT) technology to track its freight railcars as they pass through Europe and across the New Silk Road to China. The system employs Traxens' IoT technology and consists of on IoT box installed on each car, which communicates as a mesh network via short-wave radio signals to other boxes, while leveraging a GSM cellular connection to the cloud. The system is intended to improve operational processes by reducing the time required for train brake testing and providing automated data about the functionality of each set of brakes. The second feature can help to ensure the brakes don't fail during transit between stations, Traxens reports.
While CFL Multimodal is piloting the technology for brake testing this year, the Traxens system, known as Traxens Net, has been tested for fleet management as well. CFL's long-term goals are to deploy its full Digital Train solution to automate freight management and brake safety, and to share relevant data to members of the supply chain.
Traxens began developing wireless technology for rail freight management two years ago, and CFL opted to start piloting the technology last year. "The aim of CFL is to digitalize all operations concerning train controlling in order to improve the fully manual operational process," says Marc Valette, CFL's innovation director. By using IoT technology, the company intends to reduce the amount of time required to prepare trains for transit, as well as improve safety control by making the testing process more transparent and automating the recording of data.
The system was first piloted in 2018 with a Traxens Box device installed on CFL's flat wagons that travel between several stations throughout Europe, according to Florence Delalande, Traxens' rail business unit director. Since that time, the solution has been deployed on approximately 20 freight cars across wider areas. In April of this year, the pilot was expanded to 20 cars traveling from Europe to China on the New Silk Road corridor. "The initial objective was to start with brake testing," Valette explains. "We already had experience with using tracking devices and we are very confident in the technology."
Brake testing is an essential part of rail management that can prevent catastrophic failures or accidents. If a train malfunctions after it has left the station, Delalande says, that "is the worst thing that can happen." Such a scenario could not only risk the safety of the operators and the freight on board, but also disrupt all transit on that rail line. The brake-testing system, deployed to prevent such accidents, has changed little throughout the past 100 years. An engineer drives the train forward, and an individual on the ground visually confirms that each car is braking properly by climbing under the car.
