Upgrade to 4G or 5G.

  In the long term, sure, but https://en.wikipedia.org/wiki/FRMCS https://en.wikipedia.org/wiki/FRMCS is some way away, and I doubt they'll upgrade cab radios to 5G for the fallback path alone.

    I have no idea which is cheaper, upgrading those or paying for one 2G network to remain on (at least enough cell towers to cover the railway network).

      GSM-R is mainly implemented with dedicated BTSes aligned with rail line

        We were talking about the fallback system, see earlier in the thread.
