Like all of the
Reading Company's commuter lines, the West Trenton Line was
electrified in the early 1930s and has a mix of at-grade and grade separated crossings. Electrified service to West Trenton was opened on July 26, 1931. The RDG planned to also electrify tracks between West Trenton and the
CNJ Terminal in
Jersey City for long-distance service, but had to drop plans for electrification outside of the commuter service area due to economic setbacks as a result of the
Great Depression. The line north of the split at Jenkintown was originally built as the
National Railway project, opened on May 1, 1876, to provide an alternate to the
United New Jersey Railroad and Canal Companies'
monopoly over Philadelphia-
New York City travel. From Jenkintown to the Delaware River it was built by the
North Pennsylvania Railroad as a branch, while the
New Jersey section was built by the
Delaware and Bound Brook Railroad, merging with the
Central Railroad of New Jersey at
Bound Brook. In addition to the Reading Company, which leased the North Pennsylvania Railroad in 1879, the
Baltimore and Ohio Railroad also used the line for passenger and freight service to New York City, including its famed
Royal Blue service. In 1976 the Reading merged into
Conrail, and in 1983 SEPTA took over operations. Prior to 1981, limited service continued north to
Newark, New Jersey (
Jersey City prior to the
Aldene Plan of the 1960s), using
Budd Company-built
Diesel multiple units. This service was the last remains of the Reading's
Crusader service, which began in 1937 using streamlined steam locomotives and passenger cars. SEPTA ended service beyond West Trenton on August 1, 1981; connecting NJT diesel service lasted until December 1982. NJT has since considered service resumption on their
West Trenton Line. Beginning in 1984 the route was designated
R1 West Trenton as part of SEPTA's
diametrical reorganization of its lines. West Trenton Line trains operated through the city center to the
Airport Line on the ex-Pennsylvania side of the system. In later years this behavior changed; the line was designated
R3 West Trenton and trains continued on to the
Media/Elwyn Line on weekdays and the Airport Line on weekends. The R-number naming system was dropped on July 25, 2010. , most West Trenton Line trains terminate at 30th Street Station on weekdays, while most evening trains operate to Malvern or Thorndale on the
Paoli/Thorndale Line. Most weekend trains operate to Chestnut Hill West on the
Chestnut Hill West Line. On April 9, 2020, service on the line was suspended due to the
COVID-19 pandemic, though stations between Center City and were still being served by other rail services. Service resumed on June 15, 2020. == Stations ==
