President Joe Biden took thousands of train trips between his Delaware home and Washington, D.C., when he was in the Senate, earning him the title “Amtrak Joe.”

Pete Buttigieg, the incoming U.S. transportation secretary, who earned the nickname “Mayor Pete” during last year’s presidential contest, advocated for improved passenger rail service as mayor of South Bend, Indiana.

For supporters of a project to revive Amtrak on the Gulf Coast, the new Biden administration represents a potential shot of energy.
