High-speed locomotives for North America

Powering intercity, regional and long-distance travel

With a top speed of 125 mph each, Siemens Mobility ACS-64 and Charger locomotives are at the forefront of high-speed passenger train travel in North America. The electric ACS-64 locomotive, based on Siemens Mobility's successful Eurosprinter design, was originally adapted for Amtrak’s service between Boston and Washington, DC. The Diesel-electric Charger locomotive is based on more than 130 years of comprehensive global expertise in the development, production, and maintenance of rolling stock. Siemens Mobility is known for its on-time delivery of both the ACS-64 and Charger locomotives, and offers access to in-house financing. From start to finish, both locomotives are manufactured at the full-service Siemens Mobility manufacturing facility in Sacramento, California, in accordance with Buy-America regulations. Both boast the high reliability and high performance that keep North American passenger service on track.

A trusted pair of locomotives

ACS-64 electric locomotive

Known originally as the Amtrak Cities Sprinter, the ACS-64 is Siemens Mobility's first complete transfer of a high-speed electric locomotive from Europe to the U.S. In 2010, Amtrak ordered 70 locomotives for service on its Northeast Corridor. They started revenue service in 2014. Since then, 85 ACS-64 units have been put into revenue service by Amtrak and SEPTA.

Charger Diesel-electric locomotive

Its low overall weight and efficient Diesel engine make the Charger the most energy-efficient Tier 4 passenger locomotive in the industry. It has the lowest fuel consumption, can be run on biodiesel, and fulfills the EPA’s stringent Tier 4 emissions standards. It features 95% particulate matter reduction and 89% emissions reduction compared to existing Tier 0 locomotives. More than 200 locomotives have been ordered since 2014, making the Charger locomotive the market leader in its segment.

What customers are saying

“These new locomotives will offer increased reliability, more hauling power, improved safety features and lower emissions.”
Richard Anderson | Former Amtrak President & CEO
“We paid for a performance machine and this is a performance machine. This is absolutely the top end of railroading. I would argue this is probably the finest fleet in the world.”
Tom Rutkowski | VP of Engineering and Chief Mechanical Officer | Virgin Trains USA
