Interesting link, thanks. *It answers my question - GSM-R and GSM/3G can
use much of same kit and that as usual contractual details lag behind
the technology.

Subterranean mobile coverage in the London Underground has certainly
been been looked at several times, but it's never come to fruition -
e.g. see:
http://www.theregister.co.uk/2011/04...s_mobile_plan/

Seems quite possible but it's contracts again. *Perhaps this is one
thing that Boris shouldn't have expected to get for nothing.

I don't think it would have been remotely popular to use public/
farepayers money for mobile phone coverage on the Tube!

(Though Boris is rather good at promising things which will apparently
cost nothing, which then end up costing quite a bit - but in terms of
the Tube wifi contract, the costs really are being covered as part of
the commercial contract with Virgin Media.)
