Probably one of the NR telecom network switching centres on GSM-R (Global System for Mobile Communications – Railway) which is a 2G mobile digital cellular standard specifically for railway use; it is quite old tech now including the backbone system.
I believe work is being done to upgrade to FRMCS (Future Railway Mobile Communication System) which is a 4G based system and an improved backbone system, as the GSM-R becomes end of life in 2030.
