Pennsylvania Railroad Electrified Lines Map 1956 Print

From - Pennsylvania Railroad Electrified Lines Map 1956. PRR officials decided to use overhead lines to supply power to the trains. Unlike the New York terminal system, the overhead wires would carry high-voltage alternating current (AC) power. This became the type of system used for all future installations. In 1915, electrification of the line from Philadelphia's Broad Street Station to Paoli, Pennsylvania was completed. Other Philadelphia lines electrified were the Chestnut Hill Branch (1918), White Marsh (1924), West Chester (1928), and in 1930 the Norristown branch along with the main line to Trenton, New Jersey.PRR's president William Atterbury announced in 1928 plans to electrify the lines between New York, Philadelphia, Washington and Harrisburg. In January 1933, through main-line service between the principal cities was placed in operation. The first test run of an electric train between Philadelphia and Washington occurred on January 28, 1935. On February 1 the Congressional Limiteds in both directions were the first trains in regular electric operation between New York and Washington, drawn by the first of the GG1 type locomotives. All regular passenger trains between these cities were electrified by March 15, and shortly thereafter through trains to the west were electrically operated from New York City to Paoli, Pennsylvania.
