TfL installing UV devices to battle Covid-19

Transport for London (TfL) is installing over 200 ultraviolet light sanitising devices on 110 escalators on the London Underground network.

The installation follows on from a successful six-week trial earlier this year to clean the handrails on escalators at Heathrow T123 Tube station.

Designed to supplement TfL's existing anti-viral cleaning regime, they are connected to the escalator handrail and use its motion to power a UV bulb that breaks down contamination to sanitise the surface continuously.

Devices have already been fitted on six escalators at King's Cross St Pancras Tube station and in the coming weeks will be installed at some of the busiest stations on the network including Bond Street, Charing Cross, Green Park, London Bridge, Paddington, Tottenham Court Road, Victoria and Waterloo.

While UV light has been proven to de-activate previous strains of coronavirus, Covid-19 is still too new for similar clinical trials to have concluded in the UK. 

However, the UV-light sanitising devices were shown in TfL's trial to improve the cleanliness of escalator handrail surfaces by at least 50%.

Esther Sharples, director of asset operations at London Underground, said: "We already have a rigorous cleaning regime across all of our stations but are committed to doing everything we can to ensure that the transport network is as clean as it possibly can be.

“Customer injuries on escalators account for around half of all injuries on the Tube network and, during the pandemic, we have found that some customers are avoiding holding the handrails. We hope that the installation of these new devices, along with the provision of Dettol hand sanitiser across the network, will rebuild customer confidence."

TfL has regularly tested for coronavirus on the transport network with no evidence of the virus found to date and, last month, a new testing plan with Imperial College London started.

This work involves independent monthly air and surface sampling, on both the Tube and buses, for a period of four months.

The need for ongoing sampling will be reviewed at the end of the period.

The results from the first round of collaborative sampling in September have already been received and were, again, all negative for the presence of COVID-19.

TfL's anti-viral cleaning regime across the transport network includes using hospital-grade cleaning substances that kill viruses and bacteria on contact and provide ongoing disinfection.

More than 1,000 hand sanitiser points have been installed across the network for everyone to use and firm action is being taken against the minority of customers who refuse to wear a face covering without an exemption.

TfL is continuing to run a full planned service, which, along with widespread social distancing signage, makes social distancing easier on the network.
