The U7 is a rail line on the Berlin U-Bahn. It runs completely underground for a length of through 40 stations and connects Spandau, via Neukölln, to Gropiusstadt and Rudow.
Line colour and name
In 1966, the branched C line had a violet map colour. After it was separated from the rest of the line and line names were changed from letters to numbers, this route was called (), and was represented by a grey line. After 1978, however, it was changed to a bright blue, because it is more easily discerned on the map. Since 1984, when all the underground lines received a "U" prefix, it has been called "U7". Station signages use the Helvetica font which is widely used in subway systems globally.
In popular culture
In March 2009, TML-Studios released 'World of Subways Vol. 2: U7 - Berlin' for Windows, which gives players the opportunity to operate a train on the U7 Line in either F90 or H01 rolling stock.
