Mayor says London underground work back on track thanks to Tfl takeover of Tube Lines

Boris Johnson has announced 鈥渟ignificant progress鈥� on the 拢13bn Tube upgrade after the work was taken into public ownership.

The London mayor said much-needed upgrade work on the Jubilee line will be complete by the spring, thanks to Transport for London鈥檚 (TfL) takeover of contractor Tube Lines for 拢310m last June.

TfL is installing a new automatic signalling system which will provide extra capacity on the network.

The upgrade was due to be completed in 2009 but was crippled by delays after disputes broke out over line access.

Johnson said: 鈥淲ork has been progressing swiftly since TfL took control of Tube Lines and we can now see real milestones being reached, including the long awaited completion of this crucial upgrade in just a few months time.

鈥淭his is good news for the many thousands of passengers who rely on the line, and clearly demonstrates how our hands on approach to the upgrades is making real improvements.鈥�
