A spin-off from the 4g replacement for Airwave, it says. Which could
mean only EE customers will benefit. [Heigh ho, another reason for
getting a dual-SIM phone].

I'm not clear how you work that out? The article says:

"While TfL is picking up the bill for initial trial on the Jubilee line
extension between Canning Town and Westminster, it will soon award a
contract to a private operator which will install 4G equipment within all
of London’s tube tunnels by the mid-2020s. Mobile phone networks will then
pay the private operator for access to the network, with the transport
authority receiving a cut of profits."

Just before that it says:

"The upgrade, which will ultimately require around 2,000km of
new cabling, is being installed in conjunction with a
much-delayed Home Office-mandated 4G telephone network for the
emergency services, saving the need to fit two different sets of
equipment."

(Although why a new installation is called an "upgrade", only the
sub-editors can say).

That implies that the kit will be installed by a third party,

It's hardly likely to be done by TfL themselves. No budget for that kind
of thing, or something would have happened years ago.

who then charges mobile phone operators to use it, and shares the
profits with TfL. There's no suggestion that only one operator will
have access.

"Although the UK’s four mobile phone networks are is still in
negotiations about accessing the new equipment in London's tube
tunnels, TfL expects that customer demand will ensure they all
provide services on the move."

Well, EE is going to, but are-is(sic, well it is the Grauniad) the other
three going to follow suit. Who will blink first over the cost.

One way or another, I'm sure all the major, and probably all,

You expect there to perhaps be an "O2 - yes, Tesco - no" kind of
discrimination (which in another thread I think is what applies to the
wifi).

operators will provide connectivity in the tunnels.

Let's wait and see what happens.
