Who owned the electrified railway line which Newark Liberty International Airport Station (also known as Newark International Airport Station) is a railroad station on
Northeast Corridor The Northeast Corridor (NEC) is an electrified railway line in the Northeast megalopolis of the United States. Owned primarily by Amtrak, it runs from Boston through Providence, New York City, Philadelphia, and Baltimore to Washington, D.C.. The NEC closely parallels Interstate 95 for most of its length, and is the busiest passenger rail line in the United States by ridership and service frequency as of 2013. Branches to Harrisburg, Pennsylvania, and Springfield, Massachusetts, though not considered part of the Northeast Corridor, see frequent service from routes that run largely on the corridor.
Pennsylvania Railroad class DD1 The Pennsylvania Railroad's class DD1 were semi-permanently coupled pairs of third rail direct current electric locomotives built for the railroad's initial New York-area electrification. They operated between Manhattan Transfer and Pennsylvania Station in New York City, and from there to the coach yards at Sunnyside Yard in Queens, New York. Some also operated on the PRR-owned Long Island Rail Road's extensive third rail network. They had a wheel arrangement of 4-4-0+0-4-4 in the Whyte notation; in other words, two 4-4-0 locomotives coupled back-to-back, hence its class letter, as the Pennsylvania listed all 4-4-0s under Class D. In the AAR wheel arrangement notation, this is described as 2B+B2. Each half-locomotive contained one large electric motor mounted in the body and driving via a jackshaft and side rods. Those electric motors gave the DD1 a potential top speed of 85 mph , though PRR/LIRR timetables never allowed more than 65 mph. The simplicity and reliability of these locomotives allowed it to outlast its potential replacement model, the PRR L5.
