A £5.54bn investment in four London Underground (LU) lines should
improve efficiency, Transport for London (TfL) has claimed.
Work to the District, Circle, Metropolitan and Hammersmith & City lines
will include a new signalling system, new track, longer platforms and
rebuilt train depots.
Tfl said the plans for a new signalling system include the oldest part
of the network built, which was built in 1863 and "belong in a museum".
