It has 16 stops, including Providence, Rhode Island; Baltimore, Maryland; Philadelphia and New York City. On some parts of the track, the trains are able to go up to 150 miles per hour (240 km/h), this makes the Acela trainsets the fastest ones in the Americas. Acela carried more than 3.4 million passengers in 2016. Only Northeast Regional carried more people then, over 8 million. Acela 2016 revenue was US$585 million, 25% of Amtrak's total.[1][2]
