As per a previous freedom of information request that you have denied, I would like information on cancelled trains to and from Canonbury station running on the former east london line. I have simplified the previous request to ensure less work hours to comply with FOI restrictions. Please provide from 1st June 2017 to the latest date available: 1. the number and % of trains that were scheduled to stop at Canonbury station on the former East London Line (i.e. between Highbury and Islington to Clapham Junction, Crystal Palace, West Croydon) at any time, but for whatever reason did not stop there. This includes trains that were cancelled from start to finish, but also trains that are instructed to run to their scheduled final destination but miss out Canonbury. Please provide counts and % for trains to and from Highbury & Islington Station separately. 2. Please provide the same as 1 but for peak hours only and confirm what you believe peak hours to be.

Our ref: FOI-2358-1718

Thank you for your email received on 21 November 2017 asking for information about cancelled trains from Canonbury station.

Your request has been processed in accordance with the requirements of the Freedom of Information Act and our information access policy. You asked:

Please provide from 1st June 2017 to the latest date available:

1. the number and % of trains that were scheduled to stop at Canonbury station on the former East London Line (i.e. between Highbury and Islington to Clapham Junction, Crystal Palace, West Croydon) at any time, but for whatever reason did not stop there. This includes trains that were cancelled from start to finish, but also trains that are instructed to run to their scheduled final destination but miss out Canonbury. Please provide counts and % for trains to and from Highbury & Islington Station separately.

2. Please provide the same as 1 but for peak hours only and confirm what you believe peak hours to be.

Arriva Rail London’s objective is to achieve continuous improvements in train performance through working with industry partners. We have built route-by-route performance plans that tackle the key causes of delay on each route. On the East London Line services we are particularly focused on – improving the timetable so it operates with less delay, working with Network Rail to reduce instances of infrastructure failing and focusing jointly with Network Rail and Go Via Thameslink Railway (GTR) on reducing the knock-on effect of late running GTR services on the shared tracks between New Cross Gate and West Croydon/Crystal Palace.

Unfortunately, to provide you with 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 exceed the cost limit to provide a response to your current request as we would need to manually go through each service cancelled service, or trains that have not stopped at Canonbury station for the last 6 months during peak hours only.

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. 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.

We would be able to part answer question 1 within the cost limit, if you were to request information about cancelled trains or trains not stopping at any station on the Canonbury route (not just missing Canonbury station).

Please can you advise what you consider to be peak hours and which days of week you require information for?

Please see the attached information sheet for details of your right to appeal.

Yours sincerely,

Melissa Nichols
