Driverless Tube trains given red signal by TfL chief as next week's four-day Tube strike remains on

Driverless trains on the London Underground have been comprehensively ruled out by the capital’s transport commissioner.

Andy Lord said there was “no business case” to make the Tube driverless – despite the likelihood that a drivers’ strike next week will spark renewed demands from some politicians for the Underground to become fully automated as a way of reducing the power of the Tube unions.
