Very interesting, I always thought it was completely separate infrastructure by design. I wonder what they'll do once commercial GSM networks throughout Europe are shut down?

Upgrade to 4G or 5G.

In the long term, sure, but 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.
