What about National Rail?

They tend to use GSM-R
http://en.wikipedia.org/wiki/GSM-R

They will ultimately, but the infrastructure rollout and fit to the trains
has only just started. The reopened East London line is probably one of very
few lines where GSM(R) is the only option available, there are other areas
where it is used under trial conditions but with the obsolescent NRN and CSR
still available...
