Thank you for your request of 9th February 2023 asking for information about the existence of an API for data on London Underground carriage weights / passenger numbers.
Your request has been considered in accordance with the requirements of the Freedom of Information Act / Environmental Information Regulations and our information access policy.
Specifically you asked: “To develop a mobile app, I am unable to find the below data in the APIs which is essential to build the application. Please let me know the APIs where can find this data. Weight in each carriage or Count of passengers in the carriage Through my analysis I understood above data is being transferred to the backend on a real-time basis.”
I am afraid that TfL does not publish this data as open data in public APIs, nor do we have any plans to do so. Note further that, in any case, we only hold load weight data for some lines and at varying degrees of timeliness, and there is no particularly efficient way of making historic data available.
Please see the attached information sheet for details of your right to appeal.
Yours sincerely,
David Wells FOI Case Officer FOI Case Management Team General Counsel Transport for London
