Nov. 6 (UPI) -- President Joe Biden will travel to Delaware on Monday to announce $16 billion in rail improvements along the country's heaviest-used passenger rail lines, known as the Northeast Corridor, as part of his ongoing infrastructure plan.

The president, who was well known for riding Amtrak to and from Congress while serving as a U.S. senator in Delaware, will make his announcement in New Castle, at Amtrak Bear Maintenance Shops.

"The Northeast Corridor, running from Boston to Washington, D.C., is the most heavily traveled rail corridor in the United States, supporting 800,000 trips per day in a region that represents 20% of U.S. gross domestic product," a statement from the White House said.

"If the Northeast Corridor shut down for a single day, it would cost the economy $100 million in lost productivity. Despite its importance, the Corridor hasn't seen major investment in generations."
