I have seen that you have previously published reports detailing your effort's to cool the tube, however it's quite old (from 2007) Are these still produced? If so can I request a copy from 2018/19 For ease of reference the previous reports file name is "lu-cooling-the-tube-programme-presentation1.pdf"

TfL Ref: FOI-0893-1920

Thank you for your request of 26^th June 2019 asking for information about temperatures on the London Undergound.

Your request has been considered in accordance with the requirements of the Freedom of Information Act and our information access policy.

Specifically you asked:

“I have seen that you have previously published reports detailing your effort's to cool the tube, however it's quite old (from 2007)

Are these still produced? If so can I request a copy from 2018/19. For ease of reference the previous reports file name is "lu-cooling-the-tube-programme-presentation1.pdf"

The most recent such document produced by TfL dates to 2008 – found on our website here (I think this may, in fact, be the same document that you refer to in your request):

There is not a more recent version of this document. However, note that we are constantly working on ways to keep the temperature down on the London Underground and have doubled the number of fans on the network since 2012 as well as installing chiller units to pump in cold air. There are already air conditioned trains on 40 per cent of the Tube network and we are determined to do all we can to help make journeys more comfortable on other lines while investing in solutions for the longer term. 192 new air-conditioned trains are now in operation on the Circle, District, Hammersmith & City and Metropolitan lines (the sub-surface lines). We will also be introducing 94 new trains on the Piccadilly line, similar to those already running on the sub-surface lines, with the first trains serving customers from 2024.

During periods of hot weather, we advise our customers to ensure they carry water with them when they travel in order to stay hydrated, offer a seat to those who may need it, and, if they feel ill, to contact a member of staff at the next station.

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

Yours sincerely,

David Wells
