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.

The PRR put both locos through their paces and the GG1 came out on top with slightly better tracking characteristics. 4800 (originally 4899) was the prototype for the line and was the only one to have a rivited body.

Nov 1, 2024 · The iconic GG-1 is the most well known electric locomotive in the world. The model was quick and reliable that it remained in service from 1935 through 1983.

Pennsylvania Railroad 4800, nicknamed "Old Rivets", is a GG1 class electric locomotive located at the Railroad Museum of Pennsylvania, outside of Strasburg, Pennsylvania in the United States. It is the prototype GG1 and was originally numbered 4899.

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.
