Amtrak has commissioned Siemens to build 70 Cities Sprinter ACS-64 electric locomotives for use in the U.S. Northeast Corridor. Operating at speeds over 100mph, the locomotives also boast many safety upgrades as well.
The ACS-64 locomotives will be capable of operating on 25 kV, 12.5 kV, and 12 kV power supplies and will feature regenerative braking systems that can automatically return electricity to the power grid. Additional features include crash energy management components like anti-climbing technology and push-back couplers designed to keep the train upright, inline and on the tracks in the event of a collision.
