Follow-up to 0323-2223:
Dear FOI,
Thank you for your reply. I am afraid there is something going wrong.
As for the 2nd request, "the average haul distance of the Victoria Line from 2017 to 2021; -how long on average do customers travel on Victoria Line from 2017 to 2021", means that I would like to know how long in kilometres or in miles do customers travel on Victoria Line from 2017 to 2021, which is distance, not time.

TfL Ref: 0722-2223 Thank you for your request received by us on 27 June 2022 asking for information about travelling on London Underground’s Victoria line, following your previous request for passenger data, (reference: 0323-2223). Your request has been considered in accordance with the requirements of the Freedom of Information Act and our information access policy. I can confirm that we hold some of the information you require. You asked for the following: I am afraid there is something going wrong. As for the 2nd request, "the average haul distance of the Victoria Line from 2017 to 2021; -how long on average do customers travel on Victoria Line from 2017 to 2021", means that I would like to know how long in kilometres or in miles do customers travel on Victoria Line from 2017 to 2021, which is distance, not time. To recap, when requesting clarification for this part of your request previously, your email of 14 June 2022 stated that ‘I am writing to clarify "the average haul distance of the Victoria Line from 2017 to 2021". This means how long on average do customers travel on Victoria Line from 2017 to 2021’. We duly replied that ‘we do not record the average time spent travelling on the Victoria line’. However, as you have now confirmed that you would like: ‘the average haul distance of the Victoria Line from 2017 to 2021; -how long on average do customers travel on Victoria Line from 2017 to 2021", means that I would like to know how long in kilometres or in miles do customers travel on Victoria Line from 2017 to 2021, which is distance, not time’, we can advise that the Working Timetables provide the distances in kilometres for the Victoria line via: https://content.tfl.gov.uk/vic-wtt-42.pdf. For example, this schedule features ‘Scheduled Passenger Kilometres’ in the following sections: SCHEDULED KILOMETRES IN PASSENGER SERVICE – Page Four DISTANCES BETWEEN STATIONS AND APPROXIMATE INTERMEDIATE RUNNING TIMES – Page Two For the numbers of passenger journeys on the Victoria line between stations throughout the day during 2019-20, please refer to the NUMBAT data published on our TfL Crowding page. As stated in the NUMBAT introduction here: http://crowding.data.tfl.gov.uk/NUMBAT/Intro_to_NUMBAT.pdf ‘NUMBAT uses ticketing data from smartcards and gateline entry/exit totals for each station’. The ‘Link Load’ statistics, amongst other outputs published in each NUMBAT spreadsheet provides the ‘number of passengers travelling along a link between one station and another by 15min’. Please refer to the NUMBAT data available at: http://crowding.data.tfl.gov.uk/ for NUMBAT statistics for 2019 and 2020. These passenger numbers can then be collated with the aforementioned detail provided in the Victoria Line Working Timetable to provide the information you are seeking. In accordance with section 21 of the FOI Act, we are not obliged to supply you with a copy of some of the requested information as it is already accessible to you elsewhere. Unfortunately this research does not go back as far back as 2017. However, NUMBAT data for 2021 is intended for future publication. Therefore in accordance with the FOI Act, TfL is not obliged to supply you with the passenger usage information you have requested for 2021 as it is subject to a statutory exemption to the right of access to information, under Section 22 of the Act. In this instance the exemption has been applied as some of the information you have requested is intended for future publication. This exemption is subject to a public interest test, which requires us to assess whether the public interest in applying the exemption outweighs the public interest in disclosure. In this instance, it is considered that the public interest favours the publication of this information, in context and according to the pre-determined schedule, rather than in response to your request, to ensure the information is provided accurately and in an accessible manner. 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. 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.
