Safer train circulation with EGNOS

A series of trials with the Belgian state railway (SNCB), use data from the EGNOS navigation system to provide precise positioning of trains on the track at any given time. The trials are being run by train builders Alstrom in partnership with ESA.

A computer in the cab receives EGNOS data from an antenna on the roof, giving accurate precise location of the train at any time, and directly controlling signalling, braking and safety functions.
