The EMD AEM-7 is a twin-cab four-axle 7,000 hp (5.2 MW) B-B electric locomotive built by Electro-Motive Division (EMD) and ASEA between 1978 and 1988. The locomotive is a derivative of the Swedish SJ Rc4 designed for passenger service in the United States. The primary customer was Amtrak, which bought 54 for use on the Northeast Corridor and Keystone Corridor. Two commuter operators, MARC and SEPTA, also purchased locomotives, for a total of 65.

Swedish Rc4 imported and repainted in Amtrak's livery for evaluation. This locomotive performed well and would become the basis of the AEM-7.

The Rc class is the most used electric locomotive in Sweden. Rc is a universal locomotive used both in freight and passenger trains. The largest operator is Green Cargo, although SJ, Tågab, Hector Rail and the Swedish Transport Administration operate it as well. Previous operators include Veolia Transport.
