London Underground performance status for August
Request ID: FOI-1719-1920
Date published: 23 September 2019
Thank you very much for the information attached below [case ref FOI-1077-1920]. I was also wondering whether you keep data regarding the status of the tube network. For example, for the month of August, do you keep records of the status of tube lines for, let's say, every hour.
