List of electric locomotives of the PRR

This list provides an overview of the electric locomotives used by the Pennsylvania Railroad (PRR) .

Electric route network of the PRR

The railway operated 1,085 km of electrified lines, which consisted of the connections New York City - Washington, DC (part of the Northeast Corridor ) and Philadelphia - Harrisburg . In 1962, 267 electric locomotives and 500 electric multiple units ran on 2307 miles (3712 km) of tracks spanned by catenary.

The first electrically operated route was the Manhattan Transfer - New York Pennsylvania Station - Sunnyside Yard connection, which opened in 1910 . It was operated with 650 V direct voltage from a power rail painted from above . The same system was used by the Long Island Rail Road (LIRR), which was operated by the PRR until 1966.

1915 was electrified lines-25 kV Hz with a 11 AC - catenary spans. In 1933, the PRR's 650 V direct voltage operation was converted to overhead lines.

Electric locomotives
class	Construction year	number of pieces	Wheel alignment	drive	v max (mph)		Power system	Hourly output (kW)		Discarded	image	Remarks
					mph	km / h		hp	kW
AA1	1905	2	Bo' – Bo '	Paw camp	65		650 V = third rail	1400	1044	1937		Test locomotives with poor running characteristics at higher speeds. Later than Shunting locomotives used.
Odd D	1907	1	2 B	Axis motors with Hollow shaft			11 kV 25 Hz Alternating current	750	560			Half of a double locomotive . Only trial operation, but pioneer for the DD1 .
DD1	1909-1911	33	2'B + B2 '	Angled rods with a high motor	85	137	650 V = third rail	2130	1567	circa 1965		First series-built electric locomotive of the PRR. Used on the tunnel entrances to Penn Station in New York .
FF1	1917	1	(1'C) (C1 ')	Flat angled bars		33	11 kV 25 Hz Alternating current		3680	1940		Test locomotive intended for freight train operations. Too strong for the rolling stock of the time.
L5 L5a	1924-1928	24	1'BB1 '	Flat angled bars	70	110	L5: 11 kV 25 Hz Alternating current L5a: 650 V = third rail	3340	2490	1942	L5 (1 piece) L5a (23 pieces)	Originally intended as a universal locomotive for passenger and freight trains with direct or alternating current. The poor driving characteristics of the single-frame locomotive meant that only direct current locomotives were built in series, but these were not able to replace the DD1 .

P5 P5a P5b	1931-1937	92	2'C2 '	Twin engines Hollow shafts			11 kV 25 Hz Alternating current			1962	Boxcab modified = streamlined	First PRR AC locomotive built in large numbers. First used in passenger train traffic, later in freight traffic. Two variants were built: boxcab locomotives and streamlined locomotives , which were called modified .
L6	1932-1933	3	2'D2 '	Paw camp	54	87	11 kV 25 Hz Alternating current	2500	1860	1962-1968		Intended for freight train service, but too light and boxcab design that was no longer considered safe.

DD2	1938	1	(2'Bo) (Bo2 ')	Twin engines Hollow shafts	70	110	11 kV 25 Hz Alternating current	5000	3700	1962		Universal locomotive not built in series, used for the push service in the Baltimore tunnel.
FF2	1926-1929 (1958)	7th	(1'Co) (Co1 ')		55	88	11 kV 25 Hz Alternating current	3300	2460	1960-1966		A converter locomotive taken over from the Great Northern , which was only used in the pushing service for freight trains.
E2b	1951	3	Bo'Bo '+ Bo'Bo'	Paw camp			11 kV 25 Hz Alternating current	5000	3800	1964		Trial series for the replacement of the P5a. Direct motors.
