Finn Brennan, district organiser for train drivers’ union ASLEF, said: “This demonstrates that despite Boris Johnson’s bluster driverless trains are a myth for the foreseeable future. Even under the most optimistic proposals, it would be at least another 14 years before new trains on the Piccadilly line could be operated automatically. ASLEF would never accept driverless trains. We are glad that at last LUL is at last admitting that new trains will be introduced with drivers”
