Across Amtrak services nationwide, nearly half of all riders utilize the Northeast Corridor for all or part of their trip. While many of Amtrak’s NEC riders are passengers on its busiest NEC services–the Acela and the Northeast Regional between Washington, DC and Boston, MA–NEC riders also include passengers onboard Amtrak’s state-supported routes and long-distance trains, which carry riders between locations on the NEC and destinations throughout the NEC region and across the country. Amtrak owns 80% of the NEC main line.
