When they didn't have radios, they had a guard. It was the move to OPO
that - I think - drove the desire to have good comms between motorman
and signaller.

Hmm, how do you turn round a tube at Hammersmith or West Ken without
going into a tunnel?

When mobile reception comes to the tube I guess that you could use a
cab mobile as a backup, like the police do. Of course Bob will be out
on strike if they suggest that. Or if they don't suggest it.

You kick the passengers out, run non-stop empty to Green Park and then open
the doors and carry on.

Just like Airwave then - nice idea, shame about the role out...

Nooooooooooo!!!! It would never work, and if there where any other users it
would be full!
We have to suffer with airwave and while it might sometimes be upto the job
for day to day work when things go wrong is usless and you might as well try
your luck with the phones or analogue radio which often works much much
better.

It depends on the TOC, but the basics are:

+ Stop and inform the Signaller (generally by use of the Signal Post
Telephone at the next signal)

+ The train is NOT to be moved until instructed

+ Deal with the train in accordance with the TOC's contingency plan
