Transport for London (TfL) is testing a brand new tube train that will perform a crucial role on the network. The technology is being deployed as part of officials’ efforts to improve air quality on platforms and in tunnels.

The Mayor told the London Assembly on 5 July: “As part of its ongoing work to improve air quality on the Underground network, Transport for London (TfL) is exploring the latest in innovation. This includes the testing of a bespoke track cleaning train, which is currently going through TfL’s approval process to ensure it is safe to run on the Underground network.




“The trial is expected to take place later this year.”

Mr Khan also provided an update on the operation of new air filters at two Underground stations. He said: “As part of its ongoing work to improve air quality in the Underground, Transport for London (TfL) is exploring the latest developments in innovation.

“This includes the trial of an air filtration system at Baker Street, which began in May 2024. The air filtration system will be assessed over the coming months to understand its ability to handle large volumes of air, the rate at which dust is captured, its ease of maintenance and other potential issues. TfL will keep your office updated once this trial has been completed.”

The Mayor’s TfL budget for this year stated that Green Park would also get a new filter system as part of the trial.
