Central Line noise

Tom Whitby made this Rhyddid Gwybodaeth request to Transport for London

Automatic anti-spam measures are in place for this older request. Please let us know if a further response is expected or if you are having trouble responding.

We're waiting for Tom Whitby to read recent responses and update the status.

Dear Transport for London,

I wrote to you about 2 years ago regarding the noise on the Central Line (Leyton - Bank), it sounds like some sections of track have been renewed, but the noise on the Bethnal Green eastbound is seeming to get worse every journey I make. Is there some form of document I could view to see for future Central Line track improvements? Could I also have a document of the track improvements for the past year.

Is there any time track maintenance will take place in the eastern part of the Central Line?

Yours faithfully,

Tom Whitby

Dear Mr Whitby

 

TfL Ref: 1240-2122

 

Thank you for your request received by us on 29 August 2021 asking for
information about track improvements on London Underground’s Central line.

 

Your request has been considered in accordance with the requirements of
the Environmental Information Regulations and our information access
policy.  I can confirm that we hold the information you require. You asked
for the following:

 

I wrote to you about 2 years ago regarding the noise on the Central Line
(Leyton - Bank), it sounds like some sections of track have been renewed,
but the noise on the Bethnal Green eastbound is seeming to get worse every
journey I make.

 

Is there some form of document I could view to see for future Central Line
track improvements? Could I also have a document of the track improvements
for the past year.

 

Is there any time track maintenance will take place in the eastern part of
the Central Line?

 

We can advise that the noise near Bethnal Green’s eastbound rail track is
the Pandrol Vanguard track form installed to reduce ground borne
vibrations for neighbouring properties. Unfortunately, this track form
causes high levels of high pitch and roaring noise inside the train and
tunnel. Current mitigation to reduce this noise is to grind and smooth the
rail surface, although the effects only last a few months.

 

Our rail tracks are regularly patrolled and inspected; whenever a fault is
identified track maintenance is arranged to rectify the fault.
Additionally, a rail grinding train runs every nine to twelve months
smoothing any rough rail surfaces, helping with noise reduction.

 

Please see the following for details of work completed or in progress at
our stations on the eastern part of the Central line recorded on a
financial yearly basis:

 

Bank: Platform 6                                 167m Deep Tube Track
Renewal   Completed: 2019/20

 

St Pauls to Bank                                 244m Deep Tube Track
Renewal   Completed: 2019/20

 

Stratford to Leyton                              1300m Deep Tube Track
Renewal. In progress, completion due: 2022/23

 

Future works in the pipeline for 2022/23 to 2023/24

 

Leyton Platform One to Stratford            700m Ballasted Track Renewal

Dear Mr Whitby

Thank you again for your further email received by TfL on 26 September
2021. You have asked for information about sections of London
Underground’s Central line that have been grinded, given concerns relating
to noise. Your request is being considered under the terms of the

because we are in the process of finalising our response.

 

To enable us to fully consider your request, in accordance with the EIRs
we have had to extend the deadline for providing a response to 40 working
days from the date we received your request. The amended date for a final
response is now 18 November 2021 . We are working hard to ensure that you
receive a response before this date. 

 

I apologise for the delay and any inconvenience this may cause you. If you
have any queries or would like to discuss your request, please do not
hesitate to contact me.
