“Celebrating 20 years of Acela service is an incredible milestone that we are proud to celebrate. We would like to thank our customers and give them a chance to see the changes we’ve made to the experience by offering an exceptionally low fare of only $20,” said Amtrak Executive Vice President and Chief Marketing and Revenue Officer Roger Harris. “For anyone who has been curious about the premium travel experience on our flagship product, this is your chance to ride Acela for a special, low fare that is only available for two days.”

Acela is Amtrak’s premium service, serving 16 stations throughout Massachusetts, Rhode Island, Connecticut, New York, New Jersey, Pennsylvania, Delaware, Maryland, and DC. The newest fleet of Acela trains, scheduled to enter service in 2021, will feature 25 percent more seats, personal outlets, USB ports, Wi-Fi, and reading lights at every seat.
