Tube ramps up anti-viral regime with dynamo-powered UV lights 

Over 200 devices that use ultraviolet light to sanitize surfaces are to be installed across London’s sprawling tube network.

In a statement Monday, Transport for London said the technology would be deployed on the handrails of 110 escalators over the next few weeks.

According to TfL, the devices utilizes a “small dynamo” to produce power from the handrail’s movement, which in turn powers the UV bulb used to sanitize its surface.

The rollout comes off the back of a six-week trial at a tube station serving Heathrow Airport. Six escalators at King’s Cross St Pancras have now been fitted with the devices, which will also be used at other major stops such as Bond Street, Tottenham Court Road and Waterloo.
