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 "Linie 7" (English: Line 7), 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".
