Metro-North Railroad is asking passengers to "be courteous" by covering their coughs and sneezes this flu season.
The rail service is warning passengers to cover their noses and mouths with a tissue or with the bend of their arm to prevent the spread of germs.
They request riders wash their hands with soap and water or use a hand sanitizer containing at least 60 percent alcohol.
Metro-North aims to enforce "healthy habits" on their vehicles.
