What temperature does the platform have to reach before the digital advertising projectors are suspended by TFL? On the Liverpool Street & Bank platforms on the Central line?

TfL Ref: FOI-1400-1819

Thank you for your  request received by Transport for London (TfL) on 21 August 2018 asking for information about digital advertising projectors.

Your request has been processed in accordance with the requirements of the Freedom of Information Act and our information access policy. You asked:

What temperature does the platform have to reach before the digital advertising projectors are suspended on the Liverpool Street & Bank platforms on the Central line?

As stated in a previous FOI response, we do not hold this information as there is no direct correlation between the temperature of the platform and the automated shutdown of the projectors.

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

Yours sincerely,

Melissa Nichols
