The reason behind installing ATO on the Central line was to increase the
capacity of the line (to a theoretical 33 tph?). AFAIA, lineside signals were
still retained, as drivers were to control the train outside peak hours to
reduce boredom and ensure driving skills were maintained. An additional
aspect - white - was added to the signals to indicate that trains in ATO mode
were allowed to enter an occupied section, the aspect being required so that
drivers weren't confronted with the situation of ATO operated tubes sailing
through red signals.

On the Jubilee Line Extension, a Westinghouse moving block ATO system was
designed to be installed, however technical related delays have meant that
traditional signalling is being installed initially, with ATO to be
retrofitted.
