The new locomotives are designated as ALC-42 for “Amtrak Long-distance Charger, 4,200-horsepower.” They will primarily replace Amtrak P40 and P42 diesel-electric locomotives, which have a lower top speed and began service under different emissions standards 30 years ago. The first of the ALC-42’s entered service in February 2022 on the
Empire Builder route and are next to be deployed on the well-known
City of New Orleans route, running between its namesake city and Chicago.
The ALC-42 locomotives are being manufactured at Siemens Mobility’s North American rail manufacturing facility in Sacramento, California and comply with the Federal Railroad Administration Buy America Standards. The plant is one of the largest of its kind on the continent, and one of the most sustainable, using a 2.1 MWp solar panel installation to generate much of its power from the California sun. It is part of Siemens Mobility’s larger U.S. manufacturing network, with eight facilities, more than 4,000 employees and 2,000 American suppliers, including Cummins, which manufactures the Tier-4 complaint diesel engines in Seymour, Indiana.
