TfL driver based in North Greenwich tests positive for coronavirus

The man, who works on the Tube's Jubilee Line, has been off work this week after returning from holiday in Vietnam, sources told the PA news agency.

An internal message to staff said the driver, based at the North Greenwich depot, had been self-isolating but had tested positive for Covid-19 on Friday, March 13.

It is the first case of coronavirus to be reported among London Underground workers, and the network is currently running at full capacity despite fears that the government may move to shut it down to stem the spread.

"The operator is receiving support from health services and is continuing to follow Public Health England (PHE) advice to self-isolate," said the memo.

"The train operator has recently returned from a trip abroad, where it is thought the illness may have been contracted."

A Transport for London spokesman said the driver was receiving support from health services, adding that he was not working in a customer-facing area.

"The safety of our staff and customers is our top priority and we are taking all necessary precautions.

"The areas where the driver worked are being cleaned, including the depot and the trains, in line with guidance from Public Health England with whom we are working closely."

Another TfL member did also test positive for Covid-19 earlier in the week, and the news comes after Boris Johnson warned that 10,000 Brits may be affected with Covid-19 yet remain undiagnosed.

So far the UK has recorded 590 coronavirus infections, and 10 deaths. The biggest jump in cases came yesterday with 134 new infections.
