U10 (Berlin U-Bahn)

The unbuilt U10 line of the Berlin U-Bahn was part of the "200-km-plan" of 1953-55 (through 1977) and would have been a driverless train line using CBTC from Falkenberg across the city to Alexanderplatz up to Steglitz and terminating at Drakestraße in Lichterfelde. The designated letter name of the line was "F." Because a number of tunnels and stations were constructed to accommodate the proposed line with elements visible at transfer stations and elsewhere, the line is popularly known as the "Phantomlinie" (Phantom line).
