The first Amtrak Cities Sprinter locomotives have left Siemens’ Sacramento site ahead of its welcome to the network later this year.
Following a period of testing over the summer, the locomotive will begin operating on the Northeast Corridor (NEC) between Washington and New York and on the Keystone Corridor from Philadelphia to Harrisburg, Pennsylvania.
Siemens is delivering 70 new electric locomotives for the US in an order worth $466 million.
New rolling stock on the NEC fulfills one aspect of a major modernisation of the line’s trains and infrastructure.
Some locomotives currently running on the line have been in operation for 35 years, completing close to 4.5 million miles.
Amtrak president and chief executive Joseph Boardman said: “The new Amtrak locomotives will help power the economic future of the Northeast region, provide more reliable and efficient service for passengers and support the rebirth of rail manufacturing in America.”
