LONDON’S transport system could be “rapidly overwhelmed” by demand when the coronavirus lockdown is eased, according to a report leaked today.

The Strategic Co-ordination Group document states that Tube and bus capacity would be cut to just 15 per cent and 12 per cent of normal levels respectively if social distancing of a two-metre space between passengers is enforced.

RMT general secretary Mick Cash said that any moves to prematurely lift the lockdown, which is to be reviewed on May 7, is “fraught with ‎lethal danger” for transport workers.

“This leaked report is a wake-up call for anyone pushing to lift the lockdown and get transport services jacked up in preparation,” he said.

“RMT has made it clear from the start of the crisis that this trade union will agree to nothing that compromises the health, safety and livelihoods of our members. That remains our position.”

Mr Cash said that it would be “gross negligence” if the government loosened social-distancing guidelines on public transport.

A Transport for London spokeswoman said that planning was underway on how to “build up service levels.”
