Thank you for your request received by Transport for London (TfL) on 18 January 2022 asking for gradient information for Crossrail.
Your request has been considered in accordance with the requirements of the Freedom of Information (FOI) Act / Environmental Information Regulations (EIR) and our information access policy. I can confirm we do hold the information you require. You asked: I was wondering if you had a document or data that shows the gradient information for Crossrail please? Ideally It would show the gradient value and the length.
The route from Royal Oak portal to Plumstead portal (Works 1/3A and 1/3B; 1/4/A and 1/4B; 1/5; 1/6A,1/6B and 1/6C) is covered by sheets 146-172 and from Stepney Green to Pudding Mill Lane portal (Works 2/1A and 2/1B) by sheets 197-201. Due to the length of the route, it is not possible to produce a single drawing showing the gradient along the whole length of the tunnels.
In accordance with section 21 of the FOI Act, we are not obliged to supply you with a copy of the requested information as it is already accessible to you elsewhere.
If this is not the information you are looking for, or if you are unable to access it for some reason, please do not hesitate to contact me.
