We answered

Our Ref:         FOI-3274-1819

Thank you for your request received on 4 March 2019 asking for information about London Overground services in Hackney South & Shoreditch.
Your request has been considered in accordance with the requirements of the Freedom of Information (FOI) Act and TfL’s information access policy. I can confirm we do hold the information you require.
Unfortunately, to provide the information you have requested would exceed the ‘appropriate limit’ of £450 set by the Freedom of Information (Appropriate Limit and Fees) Regulations 2004.
Under section 12 of the FOI Act, we are not obliged to comply with a request if we estimate that the cost of determining whether we hold the information, locating and retrieving it and extracting it from other information would exceed the appropriate limit. This is calculated at £25 per hour for every hour spent on the activities described.
We have estimated that it would cost over £1825 to provide a response to your current request. This is because it is estimated that it would take over 73 working hours to retrieve and compile the information you have requested.
The information we hold on ‘Failed to Stop’ trains is updated manually and we are not able to extract the data you have requested through an automated report. We would have to manually check multiple reports for each day during the requested time period to identify where the failed stops had taken place. The number of part cancellations that could occur on a given day would also need to be taken into consideration when extracting this data.
To help bring the cost of responding to your request within the £450 limit, you may wish to consider narrowing its scope so that we can more easily locate, retrieve and extract the information you are seeking. We would be able to supply the total number of trains that have had a ‘Failed to Stop’ event in the last year (Q2 of your request), however any requests relating to specific locations are likely to exceed the appropriate limit.
If you want to refine your request or make a Freedom of Information Act request in future, please bear in mind that the Freedom of Information Act allows you to request recorded information held by Transport for London. You should identify the information that you want as clearly and concisely as you can, specifying the types of document that you are looking for. You might also consider limiting your request to a particular period of time, geographical area or specific departments of TfL.
Although your request can take the form of a question, rather than a request for specific documents, TfL does not have to answer your question if it would require the creation of new information or the provision of a judgement, explanation, advice or opinion that was not already recorded at the time of your request.
Please note that we will not be taking further action until we receive your revised request.
In the meantime, if you have any queries or would like to discuss your request, please feel free to contact me.
Please see the attached information sheet for details of your right to appeal.

Yours sincerely

Gemma Jacob
Senior FOI Case Officer
