SNCF, Shift2Rail and Traxens have created digital brake testing for freight trains, the companies announced at trade fair InnoTrans 2018 on Tuesday. It is the first step toward creating a fully digital freight train, the companies said. The project received certification from the French railway safety authority last week. “This is not a project or a dream, this is a reality.” Shift2Rail, SNCF Fret and DB Cargo are going to test interoperability of the system in 2019.
