TfL Ref: 2325-1819

Thank you for your email received by us on 3 December 2018 asking for information about when trains are held between stations due to unplanned events, other than routine red signals.

Your request has been considered in accordance with the requirements of the Freedom of Information (FOI) Act and our information access policy. You asked for:

any available data when trains are held between stations (for other than routine red signals) due to unplanned events. I am more interested in the 1) Metropolitan Line, 2) Jubilee Line, 3) Piccadilly Line and 4) Overground between Watford and Shepherds Bush. Is there no data at all about such delays?

We publish various London Underground and Overground train delay data in our performance reports via the following links:

We mobilise a response to any incident that stops a tube train in a tunnel for more than two minutes, when trains are not likely to move imminently.  We also have a considerable number of staff and technical responders across the network poised to deal immediately with any ‘wheelstop’ incident. For example, there are mobile ‘blue light’ responders in police vehicles that are ready to move immediately in response to a wheelstop incident at any time. However, we do not record the London Overground or London Underground data in the format you have requested.

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

Yours sincerely
