TfL extended maintenance work on Central line’s ‘Hainault loop’

TfL extended maintenance work on Central line’s ‘Hainault loop’

London Underground (LU) is putting in place final preparations to help customers make their journeys during the closure, which will see the line closed between Grange Hill and Newbury Park on weekdays and between Woodford and Leytonstone on the two affected weekends (27 and 28 October and 3 and 4 November).

The work is part of a programme of renewal works on the Central line, which was last upgraded in the 1990s with new trains and signalling, allowing automatic train operation (ATO) across the line.
As part of its Tube Upgrade Plan, Transport for London (TfL) is now refreshing the fleet of 85 trains and renewing track to give customers a better, smoother journey.
By closing the line in a ‘block’ LU has been able to accelerate the work - cutting the overall time required by more than a third, from a total of 19 days down to 12.

Block closure
Using a block closure instead of weekend works will also save more than £2m of money from the public purse.

Central line services will continue to operate between Epping and central London throughout the closure, which will deliver:
  505 metres of ballast track renewal (track, sleepers and ballast replacement) and 319 metres of new track drainage
  11 new points and crossings
  Better ride quality
  340 metres of new rails between Wanstead and Leytonstone
  Improvements to track at Newbury Park where the Central line comes out of tunnel and the rails pass from a concrete bed to ballast-based track
  Embankment stabilisation near Fairlop with 2,500 concrete planks and 330 steel posts, work which has been innovatively adapted to reduce impact on residents and enable it to be carried out alongside track works, 
        preventing further weekend engineering closures.

George McInulty, LU Programme Director of Infrastructure, said: ‘This upgrade work is essential to make the Central line as reliable and as safe as possible.
‘We apologise to anyone affected by this closure but carrying the work out during the quieter school holiday period is by far the least disruptive way to do this.
‘It will avoid a long series of individual weekend closures, save more than £2m of fare and taxpayers’ money and will reduce the overall number of closure days required by more than a third.’
The Central line is used by 900,000 passengers each day.


High frequency
These works will affect around 7,500 of those customers each weekday, so LU has put in place measures to make it easier for passengers to complete their journeys.
LU tickets will be accepted on local buses and Network Rail services between Ilford and Stratford, and high-frequency rail replacements buses will also operate throughout the closure.
LU has engaged with local stakeholders including schools and businesses about the closure.
