Upgrade between High St Ken and Edgware Road completed on schedule
Normal service has been resumed across the District and Circle lines following the completion of four weeks of upgrade works between High St Kensington and Edgware Road.
Transport for London says the month long block closure between the two stations, one of the oldest sections of the Tube network, has finished on schedule.
It says the works have improved track and equipment and will improve reliability. They include work to accommodate the new Hammersmith & City and Circle line air-conditioned trains including power upgrade on the tracks, signal renewals and lengthening platforms.
Track and drainage renewals will also help to protect track circuits from flooding, thus helping to cut down on the number of signal failures. 2,000 metres of new drainage has been laid down to replace an old system from the 1850s whilst approximately 3.5 kilometres of track from the 1940s has been replaced. This has involved around 7.5kilometres of new rail.
Specially adapted engineering trains were used to make nearly 400 trips to bring old earth out and bring equipment and new materials in including:
Over the last 100 years the old railway in the area has seen little upgrade work, but TfL says during the last four weeks it has been stripped back and rebuilt so it will last for decades to come.
David Waboso, LU’s Capital Programmes Director, says: " We’re working hard to upgrade the Tube network to provide our customers with the best possible service and this is a great example of the types of improvements that we are making across the network.
" By implementing a block closure on the Circle and District lines between High Street Kensington and Edgware Road, we have been able to complete the works in four weeks rather than the period of six months that would have been required had we carried out the work just using weekend closures.
"I hope our customers can see the positive impact that these improvements will have on their journeys and I would like to thank them all for their patience of the last few weeks."
The closure also allowed LU to carry out work to improve safety and security with CCTV and lighting.
Although the Circle and District lines will still require some weekend closures as work to upgrade the District, Metropolitan, Hammersmith & City and Circle lines intensifies, this blockade has saved several months of weekend closures.
