After planes, now all riders on trains and buses will have to mask up.
Both rail service Amtrak and bus operator Greyhound are making it compulsory to wear a face mask or covering from next week.
Starting May 11, Amtrak passengers must wear a facial covering over the nose and mouth at stations and on trains.
It is also instituting social distancing on trains, by only selling 50% of seat capacity on each train to allow passengers sufficient space to sit apart.
"Amtrak continues to operate as an essential service for those who must travel during this public health crisis. Our services will be even more critical as our nation recovers," said Amtrak president and CEO William J. Flynn.
The nation’s largest bus line Greyhound makes masks mandatory from May 13.
Passengers who board without a mask will be given a disposable one by the driver.
Young children and those unable to wear masks due to a medical condition are exempt.
Greyhound’s new policy expands nationwide rules which have already been in place in some US cities and states based on local directives.
Enhanced cleaning protocols are being undertaken at all stations and on all buses after every trip.
"Our safety-first commitment goes beyond transporting customers. We care about the health and well-being of all our passengers and employees," said Greyhound CEO Dave Leach.
