maskUPDATE from the Associated Press (4/21/22):

The Justice Department is filing an appeal seeking to overturn a judge’s order that voided the federal mask mandate on planes and trains and in travel hubs, officials said Wednesday.

The notice came minutes after the Centers for Disease Control and Prevention asked the Justice Department to appeal the decision handed down by a federal judge in Florida earlier this week.

A notice of appeal was filed in federal court in Tampa (more).

EARLIER from the Wall Street Journal (4/18/22):

A federal judge in Florida declared the Biden administration’s Covid-19 mask mandate for public transportation unlawful, throwing out its requirement that travelers in the U.S. wear masks on airplanes, trains, taxis, buses and other forms of mass transit.

U.S. District Judge Kathryn Kimball Mizelle in Tampa ruled Monday that the mandate exceeded the authority granted to the Centers for Disease Control and Prevention under federal public-health law and was issued in violation of rule-making procedures.

The administration had extended the mandate through May 3rd in order to determine the impact of the new Covid-19 variant.  

Amtrak released the following statement: “While Amtrak passengers and employees are no longer required to wear masks while onboard trains or in stations, masks are welcome and remain an important preventive measure against COVID-19. Anyone needing or choosing to wear one is encouraged to do so.” So masks are optional on the Downeaster.
