The Siemens ACS-64 , or Amtrak Cities Sprinter , is an electric locomotive designed by Siemens Mobility for use on the Northeast Corridor (NEC) and the Keystone Corridor in the northeastern United States . The design was based on locomotives Siemens created for use in Europe and Asia, but with changes to comply with American standards. The ACS-64 is built at the Siemens factory in Florin, California , located outside of Sacramento .
The first 70 locomotives were built for Amtrak to replace the railroad's fleet of aging AEM-7 and unreliable HHP-8 locomotives. The first ACS-64 entered service in February 2014 and deliveries continued until August 2016.
The Southeastern Pennsylvania Transportation Authority in Southeastern Pennsylvania operates a fleet of 15 ACS-64s since August 2018, on the agency's Regional Rail Lines.
