Cornish commuters are beginning to return to local trains but being warned by operators to use them as little as possible.
The guidance is to only use trains and other public transport if necessary after Prime Minister Boris Johnson said earlier this month that those in England who could not work from home should be "actively encouraged to go to work".
Only about a 10th of train seats are in use and there are floor markings at stations, similar to those in supermarkets, to ensure social distancing.
Managers also said that trains were getting a deep clean everyday, and there has been more cleaning of things such as handrails.
James Davis, from GWR, said many of those getting back on trains first were key health workers.
He added that the message of using trains less "seems a very strange message to have to put across, but it's the right message at this time".
One of the tendered bus companies that runs routes throughout Plymouth and Cornwall is to continue to provide a service for key workers and those who could not work from home, bosses say.
Since the lockdown, Plymouth Citybus has run a reduced service on many routes and has advised passengers to check before travelling.
To ensure social distancing rules the company has provided double-deckers on busier routes, implemented additional cleaning measures and cordoned off their drivers.
In the meantime, Great Western Railway (GWR) said it was encouraging all passengers using the trains in Devon and Cornwall to follow government advice and avoid travel by train unless they had no other option.
The train operator said this advice was helping it to prioritise its services for those who needed to make essential journeys in light of the easing of lockdown announcement made by Prime Minister Boris Johnson last week, where he said people who could not work from home should return to the workplace - but avoid public transport.
The number of people travelling on the railways has increased since last week.
The train operator Greater Anglia started running extra services again... with the number of weekday trains back up to "Saturday service" levels.
Jonathan Denby, from Greater Anglia, said more carriages had been added so people can social distance, and Network Rail released more guidance around stations, so designated walking routes were now in place.
