AFAIK, no. As it's a fully signalled move, their route knowledge training will (should) cover this situation.

I only really interacted with them at a technical level (modelling runtimes and junction margins) rather than an operational one so I may be wrong on this.

Thanks, the reason for asking is that I have been told that drivers are not specifically told which signals are approach controlled and there is an obvious link to this subject.

It's not something we're told exists. We just drive to the signals we see.

Is the driver informed verbally when this situation is being used?

No; in principle, it works in exactly the same way as any other case of approach control. The trigger speed (determined by the length of time the train has been occupying the track circuit approaching the signal) may be lower though.

The aim is simply to ensure that the train is under control - it has to slow down for the approach controlled signal, otherwise it will trip the TPWS.

How did the name “Warner” come about? Ironically, my father in law was a “Warner” and was a senior signal engineer on the Eastern Region!

It's the TCB equivalent of the old Absolute Block Regulation 5 (now 3.5?) - "section clear, junction blocked" or "warning arrangement", in which case the driver was warned by various means (including subsidiary signals with a 'W' stencil) - which is presumably how the term came to be applied more recently.
