London Overground Improvement Programme

London Overground Improvement Programme

• General Background
• Work has begun on a 326 million upgrade of
  Transport for Londons (TfL) Overground network.
  When complete, passengers will see longer trains
  and more frequent services, and will benefit from
  reliable connections to the main London 2012
  Olympic and Paralympic Games Park in Stratford.
• London Overground will run up to eight trains an
  hour during peak times on parts of the network
  when the upgrade is complete, double the current
  number and with a more reliable timetable for
  those trains. New and longer platforms at some
  stations will also allow more carriages per
  train, which will increase capacity and reduce
  overcrowding.
• Work has been fast-tracked to ensure completion
  before 2012 and is being carried out by Network
  Rail as part of plans to improve rail services in
  and around the Capital.
• As part of the program of work, Network Rail
  engineers will
• Upgrade more than 200 signals
• Renew 7km of track and 69 sets of points
• Lengthen 30 platforms
• Improve seven more stations.
• TfL are also carrying out a programme of station
  improvements on the route these include
  upgraded CCTV, PA, lighting and passenger
  information screens new signs general
  refurbishment and new lifts at some locations
  and will continue in tandem with the line
  upgrades in order to minimise disruption to
  passengers.
• Some services will need to be suspended while
  work takes place over the next eighteen months.
  TfL will provide rail replacement bus services
  while this happens to keep passengers connected
  to the public transport network.

• Works programme - Area east of Highbury
  Islington station
• Key Dates
• 19 April 2009 - Start of works on site between
  Camden Road and Highbury Grove. After this date,
  the railway will be shut every Sunday to
  facilitate the works
• 26 May 2009 - Start of work between Highbury
  Grove and Dalston Kingsland
• Christmas 2009 - All lines will be closed between
  Stratford and Gospel Oak
• April 2010 - Railway reopened
• June 2010 - Introduction of first 4 car trains
• Sequence of work
• Initially we closed the northern freight line
  through the site and establish temporary
  signalling.
• We have also started cleaning up the lineside
  area and the undergrowth on the alignment of the
  new tracks at the foot of the slope only. The
  existing overhead line electrification will be
  removed. A temporary set of buffers has been
  installed at Highbury Islington station, on the
  closed freight lines.
• There is an existing sewer running under the
  railway - this takes sewage from surrounding
  streets and rainwater from the railway cutting.
  There are two outfalls for these sewers, one at
  Caledonian Road and the other at Mildmay Park. We
  will replace these sewers, where necessary, by
  laying a new pipe in the northern side of the
  cutting, between Caledonian Road and Mildmay
  Park.
• The retaining walls between Caledonian Road and
  Liverpool Road are currently propped apart by
  timber or concrete props buried beneath the
  tracks. These props will be renewed by precast
  concrete struts, again buried beneath the tracks.
  
• The railway will then be re-laid to the new
  alignment.
• Following this, overhead line electrification and
  a new signalling system will be installed.

• How We Work On Site
• Access and Deliveries
• Our workforce will access the sites via public
  transport or will be dropped off by minibus.
• All our workforce will be briefed that this is a
  residential area and are expected to work in a
  considerate manner.
• Materials will largely be delivered by rail, and
  trains will be used to transport the spoil we dig
  out.
• We will require a limited amount of material to
  be delivered by road - largely small components
  and time sensitive material, such as ready mixed
  concrete.
• The access points for our work will be via well
  established access points at
• Salamis Yard - off Caledonian Road
• Court Gardens - off Liverpool Road
• Boleyn Road
• Working Hours
• Between April and December 2009
• Tuesday to Friday - 08.00 to 18.00
• Saturday - 08.00 to 12.00
• Sundays - 00.00 to 24.00
• Mondays - 00.00 to 18.00
• These times are to suit the Planned Closure of
  the North London Railway - we will plan our work
  to avoid carrying out noisy works during the
  hours of darkness

• Station Improvements
• In parallel with all this activity, the stations
  along the route will be renewed
• Caledonian Road and Barnsbury Station will be
  remodelled as a single island platform. A new
  footbridge will be constructed, complete with
  lifts.
• Highbury and Islington Station will have new
  platforms on the north side. These will serve the
  North London Railway, while the newly built East
  London Railway will run into the existing
  platforms. Lifts will be provided for passengers
  to the East and North London line platforms and
  the concourse will be enlarged.
• Cannonbury Station will be remodelled as a four
  platform interchange between the East and North
  London Railways. Lifts will be provided for
  passengers on the East and North London railway
  lines.
• Dalston Kingsland Station will have longer
  platforms constructed, this will involve
  rebuilding Boleyn Road Bridge.
• The construction work will take place from April
  2009 to April 2010
