TfL Ref: 1784-1819

Thank you for your emails received by us on 29 September and 12 October 2018 asking for information about transport proposals for inner London and the cleaning of London Underground trains and buses.

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

1. Changes that are reductions [or increases in a separate answer please] of service on all bus routes in Zones 1 and 2 please in two data sets:
a. Reduced/increased frequencies of buses running on the Bus route schedules
b. Reduced or varied routes of buses clearly stating if more or less stops than on the previous route
c. Please only answer concerning daytime services, exclude night buses

We publish information on our proposals for bus services, including the Central London bus consultation via the following link to our website:

In accordance with section 21 of the FOI Act, we are not obliged to supply you with a copy of the requested information as it is already accessible to you elsewhere.

2. Changes in frequencies of tube runnings planned in all zone 1 and 2 stations and tube lines
a. Please share data in divisions of
i. tube lines and
ii. minute interval projected over the day stating clearly how much it is reduced by

With the exception of the Piccadilly line service, no reductions to service frequencies are planned for implementation in Travelcard zones one and two.

In order to protect the Piccadilly line fleet from damage and resulting cancellations due to ‘flatted wheels’ caused by poor adhesion on damp leaf litter contamination, a speed restriction is imposed on some Piccadilly line sections from early October to just prior to Christmas. This means that round trips take longer to complete and in addition, one passenger train is taken out of service and converted to spread ‘Sandite’, a material designed to improve adhesion in areas contaminated with leaf litter. To allow for the extra round trip time and the missing train, a small number of peak trips are removed from the timetable during this period affecting all zone one and two stations on the Piccadilly line, apart from the very early and late trains that call at Turnham Green. These removed trips extend planned intervals between trains from two minutes and 30 seconds to three minutes for short periods. Although the timing of these periods differ between stations. Full details can be found by referring to the temporary Autumn working timetable currently in operation here: and comparing it to the standard working timetable at:, both are publically available on the Transparency section of our website.

3. Cleaning of tube trains:
a. Daily clean up routine and personnel allocation in man hours per train carriage
b. Weekly or monthly deep clean routine and personnel allocation in man hours per train carriage

Please see the following table that provides a typical cleaning schedule of London Underground trains:

08.00 - 15.00 NIGHT
23.00 - 05.30
Trains cleaned 74 0 5 335 252 26

Based on the above data over a 24 hour period we will complete:

• 409 pre service cleans,
• 252 Mini cleans
• 31 deep cleans

In reference to staff hours on daily pre-service cleans and mini cleans, across the entire London underground network we have a total of 4269 carriages and will spend approximately:

• 205 staff hours on pre service cleaning
• 756 staff hours on mini cleans
• Totalling 961 staff hours over 24 hrs on these two regimes alone
• This equates to 0.25 hours (15 minutes) per carriage.

The deep cleaning regime as highlighted above consists of 31 deep cleans over a 24 hour period consisting of

• 217 deep cleans a week
• Average staff hours per clean is 24 man hours (8 people for 3 hours)
• 744 staff hours a day
• 744*217=5208 hours a week
• 217 trains is approximately 1302 carriages (average 6 carriages per train)
• 5208/1302= Four staff hours per carriage.

4. Cleaning of buses:
a. Daily clean up routine and personnel allocation in man hours per bus
b. Weekly or monthly deep clean routine and personnel allocation in man hours per bus

Whilst vehicles are cleaned on a daily basis and undergo a deep clean at intervals as specified by the operators, TfL does not hold any further information since bus operating companies are responsible for their cleaning and maintenance. If you would like to contact them directly please see the following link for their contact details

Please not that private operating companies are not legally obliged to respond under Freedom of Information Act legislation.

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
