“…In 2015, Société nationale des chemins de fer français (SNCF) launched the “DIGITAL SNCF” strategy, which plans to rely on industrial internet, using target exclusive communication networks, data clouds, various sensors and other equipment and tools, supplemented by staff business processing, to connect the three major subjects of trains, railroad networks and station buildings through a network, forming connected equipment, connected rolling stock, connected railroad network and connected station. On the one hand, SNCF aims to achieve safe transportation, production efficiency, energy economy, work quality, etc., and on the other hand, it meets the needs of passengers for punctuality and comfort, establishing a competitive, convenient, sustainable and closely integrated railway system with future transportation for customers (Pinard, 2020). - Connected equipment plans to use technologies such as 3D printing, device sensors, energy sensors, robotics and digital testing to achieve digitization of locomotives and vehicles, digitization of repairable components and digitization of information flow.
- Connected rolling stock is planned to deploy sensors on operational trains for data collection, and the collected train data will be intelligently analyzed through computers.
- Connected railroad network plans to improve the modernization level of infrastructure maintenance through real-time remote monitoring and digitization of various parts of the railroad network.
- Connected station is planned to install sensors in equipment and facilities such as elevators and platforms at the station to improve the effective utilization rate of equipment and save energy.
