Our ref: FOI-2494-1617
Thank you for your email received on 13 March 2017 asking for information about the Hopper facility.
Your request has been considered under the requirements of the Freedom of Information Act 2000 and our information access policy. I can confirm that we do hold the information you require.
Please find attached a spreadsheet showing the 200 most popular Hopper locations in London in February 2017. This was a one-off piece of analysis and has not been carried out on a month by month basis. This data cannot be collected retrospectively as data on journeys is dissociated from individual Oyster cards after 8 weeks and not kept.
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.
If you are not satisfied with this response please see the attached information sheet for details of your right to appeal.
Yours sincerely
Graham Hurt
