TfL Ref: FOI-3172-2425

Thank you for your request received by Transport for London (TfL) on 3 January 2025 asking for information about train cancellations and station closures.

Your request has been considered in accordance with the requirements of the Freedom of Information and our information access policy. I can confirm that we hold some of the information you require. 

Specifically you asked:

Please advise the number of trains cancelled due to lack of drivers in the last 12 months. Please show by line and as a number and also as a percentage of overall number of trains. 

We do not record the percentage of trains cancelled due to a specific root cause, and we are unable to report on the number of trains cancelled by line due to a Train Operator not being available.

We may be able to provide you with our Lost Customer Hours by line as a result of a Train Operator not being available. Lost Customer Hours is used to measure the customer experience of reliability on the London Underground network. The system estimates the impact of any service disruption of two minutes or more in terms of time lost by our customers (including the knock-on effects to trains and crowding). Please note that we will not be able to correlate our Lost Customer Hours to the number of trains cancelled. 

If you would like to re-submit your request, we can look into providing this information for you. 

Also please advise how many stations were closed and for how many days due to lack of staff. 

Please see the requested data below: 

Please note the following:

Time period: 18 August 2023 to 17 August 2024. Please note that this is the latest data we can provide. Due to on-going recovery from a cyber incident, we are unable to provide data for the last 12 months. 

Station Closure Notes

• The data included is based on the station being fully closed meaning passengers cannot enter or exit the station, and all train services running through the station non-stopping so passengers cannot interchange either.
• The data does not include planned station closures or closures due to industrial action.
• Delays are recorded for durations of 2 minutes or more.
• A station can be closed multiple times during a day.  For example, once at the start of the day, and then again at the end of the day.  This will be recorded as two separate closures.
• Timings and cause of closures may be subject to change pending further review of incidents.
• All dates, times, delays and durations are captured manually and should be used as a guide. Small discrepancies in the data are not uncommon.

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. 

Yours sincerely,
