London Underground 1967 Stock
The trains had Automatic Train Operation (ATO). The train operator controls when the doors open and close and also starts the train by pressing two buttons at the same time. These buttons start the automatic process of driving the train. The trains  were built with wrap-around windows in the driving cabs and were the first London Underground trains to have windows like this. The trains were delivered with a shiny grey coat, but this soon faded to a dull grey.
