LU paying to have the infrastructure fitted so they could talk to
train drivers, and the public also using it being a bonus.
Drivers on the Victoria line could talk to control via the juice rails
in 67, I would have thought that it would have been universal by now.
LUL trains now use a GSM system, albeit on a different frequency, right?
AIUI no, online references suggest LU's 'Connect' is a TETRA based system,
like the emergency service's Airwave systems.
