The Pennsylvania Railroad Class GG1 is a class of streamlined electric locomotives built for the Pennsylvania Railroad (PRR), in the northeastern United States. The class was known for its striking art deco shell, its ability to pull trains at up to 100 mph, and its long operating career of almost 50 years.

2024年11月1日 · Both locomotives featured a center-cab, bi-directional, setup. However, the GG1 quickly proved it was the superior motor and was ultimately selected by the PRR to replace the P5. The GG1 included a continuous rating of 4,680 horsepower, which could sometimes peak as high as 10,000 horsepower, giving the locomotive impressive acceleration and ...

The GG1 was a 25 cycle (HZ) machine for which the PRR maintained their own substation to provide the 25 cycle current. Locomotives today are capable of operating on 25 HZ or 60 HZ and most railroads are using 60 HZ so they can buy power directly from the power companies and avoid the expense of maintaining their own substations.

The R-1 had a center crew cab, eight motors, was rated at 5,000 HP and it was geared for 100 mph. The two designs were sent to the test track in August of 1934 and the GG1 outperformed the R-1. After the test track the two prototypes were subjected to main line tests and the GG1 was again found to be superior.

It designed a 2-C-2 (4-6-4) box cab electric locomotive which used six 625 HP traction motors to give it a total of 3750 HP. This locomotive was designated Class P-5 and two prototypes (road numbers 4700 and 4799) were built in the railroad's Altoona, PA shops in 1931.

2023年2月2日 · This is the source of the designation GG1 – G was PRR code for a 4-6-0 steam locomotive. The body was similar in style to the modified P5a, with a steeple cab and twin central crew cabins (one facing each way – the GG1 is bi-directional), but longer – the GG1 was 80 feet long, and weighed 475,000lbs, with a striking streamlined body ...

The Pennsylvania Railroad Class GG1 were a class of electric locomotives built for the Pennsylvania Railroad (PRR) for use in the northeastern United States. Between 1934 and 1943, General Electric and the PRR's Altoona Works built 139 GG1s. It was one of the most popular types of electric locomotives ever built.

Our engine was renumbered as 4939, as 4927 conflicted with other Amtrak equipment. Controller (black) on the left. Brake stand on the right. 2.

2019年3月2日 · The center cab was intended to increase safety of the crew, after horrific past experiences with level crossings. The articulated frame enabled the long units to negotiate tight curves. Designed primarily as a passenger loco, and hence fitted with a steam boiler for passenger car heating; the GG1 or 'G' was also adept at handling freight.

2021年1月7日 · The PRR P5 class 2-C-2 electrics, first built in 1932, were the GG1’s immediate predecessors, while the New Haven’s big EP3 box cab electrics, which PRR tested, gave to the GG1 design its lanky 2-C+C-2 articulated wheel arrangement.
