MASSIVE expansion of the U-Bahn network has been proposed by the Berlin Senate. If the plans go ahead, nearly 32 km would be added to the present 143 km by 2025, with alignments reserved for a further 53 km after that.

In the short term Line U5 will be extended by 4·7 km west from Alexanderplatz to the future inter-city interchange station at Lehrter by 2006, and later by a further 2·1 km to Turmstrasse. Among medium-term plans is a 3·6 km southern extension of U7 from Rudow to Sch
