Request ID: FOI-4477-1718
Date published: 05 March 2018

You asked

Follow-up to 2955-1718)My request was to discover if/when you have cleaned the track between Liverpool Street and Mile End during the past two years. To be specific, please provide information as to the dates when the track was cleaned with the purpose of reducing vibration and noise on the line during the past two years. To be even more specific I would ask for the same information regarding the line between Bethnal Green and Mile End.

We answered

Thank you for your email received by us on 9 February 2018 asking for information about track cleaning for the purpose of reducing vibration and noise on the Central line during the past two years, with particular reference to the Bethnal Green and Mile End section.

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 some of the information you require.

I can advise that cleaning the track will not reduce vibration and noise.

In your previous request (ref 2955-1718), you asked for the following: ‘I understand TfL carries out occasional operations to clean the lines on the Underground and I am simply asking whether any such operations have been conducted on this section of the Underground in the last two years’. A programme of cleaning works was duly provided on 9 February 2018.

If, however, you require details of any engineering works undertaken to help reduce vibration and noise over the last two years between Bethnal Green and Mile End please forward your request to [email protected].

If this is not the information you are looking for, or if you are unable to access it for any reason, please do not hesitate to contact me.

Please see the attached information sheet for details of your right to appeal as well as information on copyright and what to do if you would like to re-use any of the information we have disclosed.

Yours sincerely
