The new Northern Line update program is about to start, there is good news, and there is bad news!

 

 

 

 

The following press release from Transport for London, whilst not being altered, has had reams of information (and self-congratulating puff) about the Jubilee line removed.

It looks very much like a journey to Tottenham Court Road from West Finchley will knock around five minutes from the present 26 minute journey. Not a lot, but if you make ten journeys a week for 46 weeks a year, that’s a saving of around 38 hours a year.

You may ask, ‘so what’, but as Tesco keeps reminding us – “Every little helps!”

 

New Northern line upgrade set to start

Transport for London (TfL) today announced that the main programme of works to upgrade London’s busiest Tube line – the Northern line – will commence later this year. When complete, the upgrade will deliver faster, more frequent and more reliable train services for customers, increasing capacity by 20 per cent and cutting journey times by around 18 per cent. The upgrade works are due to be completed in 2014.

Lessons have been learned from the upgrade of the Jubilee line and a new approach is being taken on the Northern line that will mean significantly fewer weekend closures than originally planned under the Public Private Partnership (PPP) contracts, with no early evening closures.

Under the PPP, Tube Lines had proposed 65 weekend closures on the Northern line, many of which would have closed the whole line, or large parts of it. Instead there will now be:

  • just eight weekends of full line closures for the installation and testing of the new signalling system, spread out so as to cause minimum disruption, with five closures in 2013 and three in 2014,
  • eight additional weekends where shorter sections of the line will be closed, many of which will affect only the High Barnet branch, the most lightly-used section of the line; and,
  • six closures of parts of the line during the quieter Easter and Christmas holiday periods which will be closed for 4 or 5 days respectively

Tube Lines had also, under the PPP, planned 18 months of weekday early evening closures affecting the whole line, with last trains due to have left the centre of London by 2200; instead of this, from October, the northern branches of the line will in turn start up slightly late on Sundays to allow for extensive work during Saturday night’s engineering hours to be completed.

This will give greater flexibility to install and test the signalling and will impact on considerably fewer people than either early evening closures of a series of weekend closures. Services on the High Barnet branch will start from 8.30am on Sundays through to November 2012, followed by the Edgware branch through to November 2013.

Overall, this represents a reduction of over 60 per cent in the number of passenger journeys that will be disrupted by the work compared with the number that would have been disrupted under the original PPP plan.

Isabel Dedring, the Mayor of London’s Deputy Mayor for Transport, said: “Delivering more reliable journeys for Londoners wherever they are on the transport network is a top priority for the Mayor. The team at the Underground have completely overhauled the Northern Line upgrade programme to ensure that passengers do not have to go through a repeat of the disruption they suffered with the Jubilee Line upgrade.”

In order to achieve this reduced closure programme London Underground will be intensifying the amount of work done during night-time engineering hours, using the hours where the network is closed each night in full to carry out upgrade works, as well as the usual maintenance work.

In addition, much more system testing will be done ‘off site’ using improved simulators, and on an extended and enhanced test track at Highgate, to reduce the time needed for closures and to drive out any problems in the system before it goes live for passengers. Improvements made for the Jubilee line system (which uses the same hardware and software) will automatically be carried across to the Northern line. 

Staff who will operate the system on a day to day basis, including train operators, will also have a greater involvement in putting the new system through its paces in simulators to iron out issues off site. These new approaches will together help to ensure that the new system is reliable once it is used in passenger service.

The upgrade will proceed in phases to minimise risk, starting with off-site software development and testing, followed by the new system being applied in the High Barnet area before being rolled out across the rest of the line.

London Underground Managing Director, Mike Brown, said: “We know how disruptive weekend engineering works can be and we’re determined to learn lessons from the Jubilee line upgrade, the last of the PPP upgrades. Working with our signalling contractor Thales, we’re adopting a new and innovative approach which means we will be able to greatly reduce the disruption to our customers and businesses along the Northern line.

“The Northern line is the busiest line on the Tube network and some of the signalling dates back to the 1950s. Its essential upgrade will deliver huge benefits for passengers – with more frequent services, quicker and more comfortable journeys, and the capacity to carry an additional 11,000 passengers an hour. While we do this vital work we will do our utmost to keep disruption to an absolute minimum.”

The revised and less disruptive closure programme has been welcomed by groups representing businesses along the line. Simon Pitkeathley, Chief Executive, Camden Town Unlimited said:

Whilst there is still pain for business in this closure programme it is a substantial and meaningful improvement upon the original suggestions, which would have sounded the death knell for Camden Town. We are delighted with the progress that has been made as a result of the partnership approach now taken by LU under the leadership of Mike Brown and will continue to work closely with him as this programme is executed. We very much hope that the lessons learned on the Jubilee Line will bear fruit for the Northern Line.”

  • The Northern line is the busiest line on the Tube network with more than 900,000 passengers each day.
  • Much preparatory work for the Northern line upgrade has already been done – putting in new trackside wiring and other equipment, and converting the line’s trains so they’re ready for the new system. Much of the work has been done at night.
  • In addition to the upgrade work, the Northern Line needs essential track renewal in the next two years, not linked to the signalling upgrade. This pre-planned work is essential and the nature of it – including heavy engineering to replace tracks and sleepers – means it cannot all be carried out in the limited New Northern line upgrade set to start
  • New post-PPP approach to upgrade will mean far fewer closures and a reduction of over 60 per cent in the number of disrupted passenger journeys
  • More and better “offline” testing to ensure the reliability of the system when it goes live for passengers
  • Capacity to be increased by 20 per cent and journey times to be cut by around 18 percent by 2014
  • Jubilee line upgrade on-track for completion at the end of July
  • Increased capacity by 20 per cent, cutting journey times by around 18 per cent.

Following Transport for London’s acquisition of Tube Lines last summer the Jubilee line upgrade is now on-track for completion at the end of next month. The upgrade will mean faster and more reliable journeys and an increase in capacity of 33 per cent – space for around 12,500 extra passengers per hour. Services will initially increase from 24 to 27 trains per hour, with further increases at the start of next year.
