A question from Newbie

Greetings

When all the trains in the Tube are run by computer will speed signs,signals etc around the tracks still be kept for the "driver" who is on board monitoring the train?

Many thanks

As long as drivers are still on trains, conventional signalling and signage will always be required as a backup. But that begs another question...
