The Pennsylvania Railroad (PRR) was a pioneer in electrification, with electric operations that were more extensive than casual observers may realize. After an experimental start with a DC third-rail system in the early 1900s, PRR built an extensive AC catenary system between 1915 and 1938, powering an impressive array of electric locomotives. However, over time, diesel trains began to replace electric operations, and today, abandoned catenary structures stand as reminders of PRR's once-electrified lines.

Early electrification attempts
The Pennsylvania Railroad (PRR) began electrifying its lines as early as 1895 when a PRR subsidiary transit line in New Jersey received a third rail. This short-lived experiment involved a single wooden trolley car, but it was abandoned when the power station burned down.
In 1905, a committee of top PRR and Westinghouse engineers formed to create a heavy electric "motor" (as electric locomotives have come to be known). They soon produced a pair of basic box cab B-B units numbered 10,001 and 10,002. These were essentially compressed trolley cars with steel bodies, and they proved inadequate for the task. They lacked the power needed for heavy mainline trains, and they were rough riding and prone to damage at speed.
In 1905, electrification began on the Long Island Railroad and various transit districts, and in 1906, New York's Pennsylvania Station and the tunnel under the Hudson River were electrified. These projects used 650 volts DC supplied by a third rail. The first significant heavy power, the DD-1, was introduced in 1909. By 1910, the system was complete, and long-haul trains were able to exchange their road power at Manhattan Transfer, travelling under the Hudson to Penn Station.
Over the next few years, several designs of what have come to be called "Universal side-rodders" were created. These "Universal" motors would rule the PRR until evolving electrical technology made them obsolete in the 1930s. The first of these, the box cab DD-1s, arrived in 1909 and helped with the tunnel construction. By 1910, when Penn Station opened, 24 pairs were in operation.
In 1915, the PRR electrified its suburban Philadelphia lines to Paoli, Pennsylvania, and in 1918, the Chestnut Hill Branch. Overhead lines supplied power to the suburban trains running out of Broad Street Station. This system carried 11,000-volt 25-Hertz alternating current (AC) power, which became the standard for future installations.

The Pennsylvania Railroad's electric empire
The Pennsylvania Railroad (PRR) is renowned for its extensive electric operations, particularly its GG1 electric locomotives. However, its journey towards electrification began tentatively in the early 1900s with a limited D.C. third-rail system. This early experiment was short-lived, and the PRR soon embarked on a grand project—the construction of an A.C. catenary empire.
The PRR's electrification story started in 1895 when a subsidiary transit line in New Jersey employed third-rail electrification. Unfortunately, this endeavour ended swiftly when the power station burned down, and the line reverted to steam power. The PRR returned to electrification in 1905, starting with the Long Island Railroad and various transit districts, including the North River Tunnels under the Hudson River, providing a direct connection from New Jersey to Manhattan.
In 1905, a committee of PRR and Westinghouse engineers designed a pair of basic box cab B-B units, numbers 10,001 and 10,002, marking the beginning of the "Universal side-rodders" trend. However, these units proved inadequate for the task, as they lacked the power required for main line trains and were prone to damage at speed. Despite this setback, the PRR persevered, and by 1910, it had a fleet of 80 MP1 and MP2 class wooden MU coaches.
The PRR continued its electrification efforts, focusing on the Philadelphia terminal area and suburban lines. On September 12, 1915, the line from Philadelphia to Paoli was completed, marking the first of several Philadelphia lines to be electrified. This included the Chestnut Hill Branch, White Marsh, the main line to Wilmington, West Chester, and the Trenton line. In 1928, PRR president William Wallace Atterbury announced ambitious plans to electrify the lines connecting major cities: New York, Philadelphia, Washington, and Harrisburg.
Between 1928 and 1938, the PRR electrified its lines from New York City to Washington, D.C., and Chicago to Philadelphia, as well as several commuter lines and major freight lines. The PRR's electrification projects culminated in the completion of the Pennsy's eastern seaboard electrification program in 1938, with 2,677 miles (4,308 km) of electrified track, representing 41% of the country's electrically operated standard railroad trackage.

The PRR's electric locomotives
The Pennsylvania Railroad (PRR) is renowned for its extensive electric operations and pioneering electrification, particularly with its GG1 electric locomotives. The PRR's journey with electric locomotives began tentatively in the early 1900s with a limited D.C. third-rail system. This early experiment involved a wooden trolley car but ended after the power station burned down.
In 1905, the PRR formed a committee with Westinghouse engineers to develop a heavy electric "motor". This collaboration resulted in the creation of two basic box cab B-B units, numbered 10,001 and 10,002. However, these prototypes were inadequate for the task, as they lacked sufficient power and had issues with ride quality and damage susceptibility at speed.
Building on this experience, the PRR engineers went back to the drawing board and evolved a new concept: a box cab with a large motor powering large drivers through jack shafts and side rods. This design trend led to the creation of the "Universal side-rodders", which dominated the PRR until evolving electrical technology made them obsolete in the 1930s. The PRR's first production lot of road power were the box cab DD-1s, with the first appearing in 1909, helping with tunnel construction under the Hudson River.
The PRR continued to electrify its lines and, between 1915 and 1938, built an impressive A.C. catenary system. This expansion included electrifying the lines from Philadelphia to Paoli, Pennsylvania, in 1915, and the Chestnut Hill Branch in 1918. The PRR also electrified major freight lines, such as the one from Harrisburg and Enola Yard in 1938, completing its eastern seaboard electrification program. The PRR's electrification projects extended to various locations, including New Jersey, New York, and Philadelphia, with a focus on both commuter and long-haul services.

The PRR's electrification legacy
The Pennsylvania Railroad (PRR) is known for its extensive electric operations and impressive electric locomotives. The PRR's electrification legacy began as early as 1895 when a PRR subsidiary transit line in New Jersey received third-rail electrification. This short-lived experiment was abandoned after the power station burned down, and the line reverted to steam power.
The PRR's electrification story truly began in 1905 with the electrification of the Long Island Railroad and various transit districts. In 1905, a committee of top PRR and Westinghouse engineers developed a pair of basic box cab B-B units, which were the first electric locomotives for the railroad. However, these units proved inadequate for the task, as they lacked the power required for main line trains and were prone to damage at speed. Despite this setback, the PRR continued to innovate and experiment with electrification.
In 1906, electrification was introduced to the new Penn Station in New York City and the tunnel under the Hudson River, providing direct service from New Jersey to Manhattan. This was followed by the electrification of the Philadelphia terminal area in 1909, where overhead lines supplied power to suburban trains running out of Broad Street Station. The PRR utilized overhead catenary wires electrified at 11 kV and 25 Hz, which became the standard for future installations.
Between 1915 and 1938, the PRR built an impressive AC catenary empire, electrifying its lines between New York, Philadelphia, Washington, and Harrisburg. By 1938, the PRR had electrified 2,677 miles of its track, representing 41% of the country's electrically operated standard railroad trackage. The PRR's electrification efforts resulted in the development of various electric locomotives, such as the GG1, which became a landmark of American industrial design.
While some of the PRR's electrified lines have been dieselized or abandoned, portions of the electrified trackage are still in use today, owned by Amtrak and other railroads. The PRR's electrification legacy paved the way for the future development and expansion of electric railroads, with the PRR once known as a pioneer of electrification.

Electrification of other US railroads
The electrification of railroads in the United States began in the early 20th century, with many private railroad companies seeking to electrify portions of their networks. Despite this early start, less than 1% of mainline railroad trackage in the US is electrified today, which is quite rare compared to most European or East Asian rail networks. This is partly due to the high upfront costs of electrification, which led US railroad companies to switch to diesel-powered locomotives in the early to mid-20th century.
One of the first major railways to be electrified was the New York, New Haven, and Hartford Railroad, which adopted 11 kV, 25 Hz single-phase AC. The Pennsylvania Railroad also electrified its lines in New York and Philadelphia in the early 1900s, and by 1938, it had electrified 2,677 miles (4,308 km) of its track, representing 41% of the country's electrically operated standard railroad trackage at the time.
Other railroads that have been electrified in the US include the Norfolk and Western Railway (N&W), which had an electrified district of 52 miles (84 km) from 1913 to 1950, and the Virginia and Southwestern Railway (VGN), which had an electrified district of 134 miles (216 km) of mountainous terrain built in the 1920s. The Northern Indiana Commuter Transportation District also operates an electric service along the South Shore Line, which runs from South Bend, Indiana, to Chicago.
In recent years, there have been calls for more widespread electrification of US railroads, highlighting the advantages of electric railways over diesel-powered ones, including better energy efficiency, lower emissions, and lower operating costs. However, the transition to a nationally electrified rail system is not trivial, and industry and government analysts are skeptical about the feasibility of such a plan.
