AEM7
The EMD AEM-7 is a twin-cab four-axle AAR wheel arrangement#B-B, B-B electric locomotive manufactured by Electro-Motive Diesel, 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 Train, MARC and SEPTA, also purchased locomotives, for a total of 65. Amtrak ordered the AEM-7 after the failure of the GE E60 locomotive. The first locomotives entered service in 1980 and were an immediate success, ending a decade of uncertainty on the Northeast Corridor. In the late 1990s, Amtrak rebuilt 29 of its locomotives from DC to AC traction. The locomotives continued operating through the arrival of the final Siemens ACS-64 in June 2016. MARC retired its fleet in April 2017 in favor of Siemens Chargers, and SEPTA retired all seven of its AEM-7s i ...

Metroliner (train)
The ''Metroliners'' were extra-fare High-speed rail, high-speed trains between Washington, D.C., and New York City which operated from 1969 to 2006. They were briefly first operated by Penn Central Transportation (successor to the Pennsylvania Railroad, which originally ordered the equipment), then by Amtrak for 35 years. Service originally ran with Budd Metroliners, self-powered electric multiple unit cars designed for high-speed service. These proved unreliable and were replaced with locomotive-hauled trains in the 1980s. The trains had reserved business-class and first-class seating. The fastest trips between New York Penn Station and Washington Union Station were scheduled for 2.5 hours, though some midday trains around 1980 had schedules as long as 4 hours. Amtrak replaced ''Metroliner'' service with the high-speed ''Acela Express'', which runs up to in revenue service. The first ''Acela Express'' trains ran in 2000, but due to equipment difficulties at the time they did ...

Budd Metroliner
The Budd Metroliner was a class of American electric multiple unit (EMU) railcar designed for first-class, high-speed service between New York City and Washington, D.C., on the Northeast Corridor. They were designed for operation up to : what would have been the first high speed rail service in the Western Hemisphere. Although was reached during test runs, track conditions and electrical issues limited top speeds to in revenue service. The single-ended units were designed to be arranged in married pair, two-car sets, which were in turn coupled into four to eight-car trains. The Pennsylvania Railroad (PRR) ordered 61 Metroliner cars from the Budd Company in 1966 as part of a collaboration with the federal government to improve railroad service between New York, Philadelphia, and Washington. After difficulties testing the cars, PRR successor Penn Central began its eponymous ''Metroliner (train), Metroliner'' service on January 16, 1969. Amtrak took over the service in 1971. Desp ...

Passenger Car (rail)
A passenger railroad car or passenger car (American English), also called a passenger carriage, passenger coach (British English and International Union of Railways), or passenger bogie (Indian English) is a railroad car that is designed to carry passengers, usually giving them space to sit on train seats. The term ''passenger car'' can also be associated with a sleeping car, a baggage car, a dining car, railway post office and prisoner transport cars. The first passenger cars were built in the early 1800s with the advent of the first railroads, and were small and little more than converted freight cars. Early passenger cars were constructed from wood; in the 1900s construction shifted to steel and later aluminum for improved strength. Passenger cars have increased greatly in size from their earliest versions, with modern bi-level passenger cars capable of carrying over 100 passengers. Amenities for passengers have also improved over time, with developments such as lighting, he ...

Diesel Locomotive
A diesel locomotive is a type of railway locomotive in which the prime mover (locomotive), power source is a diesel engine. Several types of diesel locomotives have been developed, differing mainly in the means by which mechanical power is conveyed to the driving wheels. The most common are diesel–electric locomotives and diesel–hydraulic. Early internal combustion engine, internal combustion locomotives and railcars used kerosene and gasoline as their fuel. Rudolf Diesel patented his first compression-ignition engine in 1898, and steady improvements to the design of diesel engines reduced their physical size and improved their power-to-weight ratios to a point where one could be mounted in a locomotive. Internal combustion engines only operate efficiently within a limited power band, and while low-power gasoline engines could be coupled to mechanical transmission (mechanics), transmissions, the more powerful diesel engines required the development of new forms of transmiss ...

Siemens ACS-64
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 (SEPTA), in Southeastern Pennsylvania, operates a fleet of 15 ACS-64s since August 2018, on the agency's Regional Rail Lines.

GE E60
The GE E60 is a family of six-axle C-C electric locomotives made by GE Transportation Systems (GE) between 1972 and 1983. The E60s were produced in several variants for both freight and passenger use in the United States and Mexico. GE designed the locomotive for use on the Black Mesa and Lake Powell Railroad (BM&LP), a dedicated coal-hauling route in Arizona, which began operation in 1973. That same year GE adapted the design for high-speed passenger service on Amtrak's Northeast Corridor. The largest customer was Ferrocarriles Nacionales de México (NdeM), the state-owned railroad in Mexico, which bought 39 for a new electrification project in the early 1980s. The E60s were successful in the coal-hauling role. They ran on the BM&LP for decades and remain in use on several mining railroads in the Western United States. The passenger variants failed in their intended role. Problems with the truck design caused derailments above , rendering the locomotives unusable for high-s ...
