Our ref: FOI-0319-2425

Thank you for your request received by Transport for London (TfL) on 26 April 2024 asking for information about the D3 bus.

Your request has been considered under the requirements of the Freedom of Information Act 2000 and our information access policy. 

I can confirm that we do hold the information you require. You asked:

1, Number of times curtailment decisions were made for bus D3 per day in the past 12 months

Please see the attached spreadsheets.

Some useful information on the data provided:

• The Lost Mileage Cause summary shows the number of trip segments that was lost due to mechanical (i.e. on road breakdown/defective wheelchair ramp), staff (i.e. absences/lateness), traffic, other deductible (i.e. staff error) and other non-deductible (i.e. road closures) reasons.
• There are two curtailment attachment spreadsheets, one for each direction on Route D3. They show the scheduled no. of trips, and no. of trips observed at each scheduled stop. If the number of observed trips is less than the scheduled number, this means a number of trips were missing (i.e. did not operated at all as scheduled, or trips were operated but curtailed before reaching a particular stop.)
• The data also provides percentages of trips that serve each stop, including trips that were lost in full, at the beginning, in the middle and at the end.

2, Number of complaints made to D3 in the past 12 months

3, What has TfL done in response to the complaints regarding bus D3

We work closely with the Bus Operators to respond to any customer comments in line with our internal governance. Any specific driver action that has been taken as a result would be held by the Bus Operator as the direct employer and not TfL.

4, Passenger statistics of D3 in the past 12 months

For the period from 01 April 2023 to 25 April 2024, there were 1,376,767 boarders on route D3 based on Oyster Card and Contactless Payment Card transactions. This figure does not include passengers using paper tickets or not validating their ticket when boarding.

If you are not satisfied with this response please see the attached information sheet for details of your right to appeal.

Yours sincerely,

Tahsin Prima
