I'd hope it wasn't necessary - from memory of my short time playing
with GSM-R the vast majority of the "technology" was just a big IN
platform in the network and a vast number of strange rules, so
realistically any GSM handset should work (although were there
changes to ensure they worked at full HST speeds, in which case I
wish the cottage industry luck with fixing that kind of thing!)

Actually - I've just looked and they decided to use different
frequencies which introduced a level of protectionism that seems
unnecessary.

Maybe I didn't express myself clearly but the cottage industry is for the
NRN (and radio signalling in the Highlands) environment, not GSM-R which I
think has now replaced NRN. For a long time NRN had shut down in the south
but continued in the north. Maybe you are right that a similar industry will
not arise for GSM-R in due course but there is no successor on the horizon
at present of course.
