Thanks for that John. I think that either the author is mistaken or the description is somewhat misleading. It says....
" By the time Tornado is in service, the new TPWS (Train Protection and Warning System) will be required. This is designed to be a direct replacement for the AWS as fitted to air braked diesel and electric stock...
The way I read this is that it's suggesting that a new TPWS installation replaces AWS. If so then it's misinformed. AWS is still very much a respected Safety System. In fact TPWS is integrated with AWS on modern traction units, and the two are inter-dependant. The AWS cancelling button is used to cancel a TPWS brake demand once the train has come to a stand - The brakes won't release until you've done so.
Under current Rules, if AWS is faulty on a modern train, then the train is restricted to 50 MPH unless a competent person can be found to ride in the cab with the driver. That shows how important AWS is still seen to be. As a driver, AWS is wonderful because it acts to prevent an incident happening - eg, missing a precautionary aspect due to drowsiness or distraction. TPWS only intervenes when you've already messed up !!
AFAIAA There are no plans to phase out AWS from the British Railway System at this time.
NB: I'm not saying this as an arsey response, I'm just singing the praises of AWS. It might be old and unsophisticated, but most drivers have been saved alot of embarrassment by it. I love it.

The story of the creating of this new loco is worth reading if you have an hour or so to spare.

Yes, that's an excellent website. I've bookmarked it and will return there when I've got more time. Thanks for that.
