Some of Londons biggest transport hubs were almost empty on Monday morning despite more trains running.
Train companies are increasing services to 70% of standard timetable capacity.
But to allow social distancing, many services are running at just 10% of normal capacity and passengers are still being urged to avoid all non-essential travel.
The King’s Cross concourse was dotted with stickers reading “Protect your NHS, stay 2M apart”, while regular announcements urged people to stick to social distancing measures.
There were many more staff on duty than travellers, as well as several police officers on patrol around the station and neighbouring St Pancras.
The few commuters waiting for trains were mostly pessimistic about how well everyone would be able to keep two metres apart once passenger numbers start to rise.
Pc Jason Kelly, who was on his way to his home in north Hertfordshire after a night shift, said:
Up until a week ago, in the early morning there were only two people on the train. When they changed the lockdown last week that went up to about 30 or 40 people.
He thought people would find it hard to remember social distancing guidelines.
For some people it’s just like a normal day, people have got fed up with it (coronavirus), they’ve had enough.
Daniel Croft, 37, has been dividing his time between London, where he works as a security guard at Kensington Palace Gardens, and his home in Darlington, County Durham, throughout the shutdown.
The trains have been completely empty, even this last week – even the Tubes have been empty.
When asked if he thought people would try and maintain social distancing as commuter numbers rise, he said:
No – even if you walk through Hyde Park it is absolutely rammed, people don’t try and stay apart.
Victor Stringer, 69, was more optimistic about travellers sticking to the guidance.>Mr Stringer, who manages a residential building of mostly older residents in Mayfair, spends four days a week in London and the rest of his time at home in Peterborough.
It’s been so quiet, I could almost have realised my boyhood dream of riding upfront with the driver. The residents in the building I manage have been very frightened, that’s why I resolved to keep coming into work – I took a lot of stick about it from my scientist sister.
