Dear Crossrail Limited, Please could you provide the track/signalling diagram covering Plumstead depot area, and the connection towards Abbey Wood, in electronic format. Ideally this would be the same type of file as provided in FOI-0103-2021/GH (https://www.whatdotheyknow.com/request/tracksignalling_diagrams#incoming-1572985). I believe the drawing number for this file is C620-SIC-R2-DDE-CR001-00006, but any equivalent or more up to date document will be acceptable.

TfL Refs: FOI-0926-2021 and FOI-0927-2021

Thank you for your requests received by Transport for London (TfL) on 27^th August 2020 asking for information about the Crossrail project.

Your requests have been considered in accordance with the requirements of the Freedom of Information Act and our information access policy. 

Specifically you asked:

“To help understand the depth of Train Describer data, published through the Network Rail Open Data platform, I request configuration files for the Train Describer covering the Crossrail COS signalling area (TD.net Area ID 'Q0').

Specifically, the scope of my request is limited to any files which define Train Describer berth stepping arrangements and S-Class signalling address allocations. Typically these would be contained in Stepping Tables, Block Schematics, and Signalling Output Tables/External TD Communications Specifications, however I am unfamiliar with the CBTC system being used and the names used for such files on this system.

Where this information exists, could you please provide the latest electronically available version of these files?”.

And;

“Please could you provide the track/signalling diagram covering Plumstead depot area, and the connection towards Abbey Wood, in electronic format. Ideally this would be the same type of file as provided in FOI-0103-2021/GH (https://www.whatdotheyknow.com/request/tracksignalling_diagrams#incoming-1572985).

I believe the drawing number for this file is C620-SIC-R2-DDE-CR001-00006, but any equivalent or more up to date document will be acceptable.”

I attach the documents that we hold in relation to your requests. Note that any personal information has been redacted under section 40(2) of the Freedom of Information Act, the exemption that protects against the unfair release of personal data.

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.

If you are considering submitting a further FOI request please think carefully about whether the request is essential at this current time, as answering FOI requests will require the use of limited resources and the attention of staff who could be supporting other essential activity. Where requests are made, please note that our response time may be impacted by the current situation.

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,

David Wells
