The fastest Acela schedule between Boston and New York in 2016 was six hours 38 minutes for the 457 miles from Boston New York (Amtrak Northeast Corridor schedule W4-200M—1/1/16) —an average of slightly less than 69 miles an hour. The Northeast Corridor is more congested and there are more population centers between endpoints than the Burlington route between Chicago and St. Paul, but the former also allows much higher rates of speed in places than the 90 mph of the Zephyrs.
