TfL to reduce temperatures on Tube network with cooling solution trial

26 July 2022/Categories: Rail


Transport for London (TfL) is trialling a cooling panel on a disused platform to test its suitability for reducing temperatures on the deep Tube network.

TfL's trial comes as the UK experienced its hottest temperatures on record. The cooling panel aims to provide cooler air to passengers waiting on platforms, as well as mitigating potential temperature increases associated with running an increased number of trains on the Piccadilly line, as part of the line's future capacity upgrade. 

The cooling panel works by circulating cold water around pipework within a curved metal structure to chill it. It then circulates air, using an industrial-sized fan, through gaps in the panel's structure, which in turn is cooled. The panel could also have the additional benefit of halving operational and maintenance costs, compared to existing technology used to manage temperatures on Tube lines. 

The trial is part of the Government's TIES Living Lab programme, a collaboration of 25 partners focusing on 10 infrastructure, data research and digital demonstrator projects, of which the cooling panels are one. The cooling panel project was 70 per cent funded by the Department for Transport and Innovate UK. The convection cooling system has been designed by TfL and developed by SRC Infrastructure, which also managed its build. 

Paul Judge, TfL's Project Director for the Piccadilly Line Upgrade, said: "This innovative trial is taking place as we are experiencing record high temperatures. This new technology could play an important role in ensuring we are doing everything we can to protect TfL's network against future temperature increases, helping to keep staff and customers safe and comfortable.”
