From
the BBC» A severely reduced number of passengers will be allowed to use the Tube network in order to stick to strict social distancing rules, a leaked Transport for London (
TfL» ) report has warned.
Its message is extremely stark - with social distancing it will only be able to transport tens of thousands of commuters rather than hundreds of thousands.
The report shows the current service would be able to handle 30,000 passengers with 2m distancing
The report, seen by BBC London, shows that even with a 100% service and two metre social distancing, only 50,000 passengers could board every 15 minutes. That compares to 325,000 normally boarding every 15 minutes at the peak of rush hour prior to lockdown.
