The Pennsylvania Railroad 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.
Between 1934 and 1943, General Electric and the PRR's Altoona Works built 139 GG1s. The GG1 entered service with the PRR in 1935 and later ran on successor railroads Penn Central , Conrail , and Amtrak . The last GG1 was retired by New Jersey Transit in 1983.
Most have been scrapped, but sixteen are preserved in museums.[ 1] [ 2]
