Thank you for your request received by Transport for London (TfL) on 28 February 2023 asking for information about wagons used on London Underground’s District line.

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

From the description provided, we believe that this machine is the DISAB. This removes ballast from under the track, without having to remove the rails or sleepers, using suction through the hose, whilst the other wagons are used to replenish with new ballast and consolidate.

In the meantime, as mentioned in my acknowledgement, your feedback concerning the ‘I’m not a robot’ has been forwarded to our Customer Services team to address.

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
