A GG1-class locomotive is 79 feet 6 inches (24.23 m) long and weighs 475,000 pounds (215,000 kg).[1] The frame of the locomotive was formed from two bridge-like trusses joined together with ball and socket joints.[2] The body rested on the frame and was clad in welded steel plates. The two cabs are in the middle of the locomotive, situated for greater crew safety in the event of a collision.[3] A pantograph mounted on each end of the locomotive body was used to collect the 25 Hz, 11,000 V alternating current (AC) from the overhead lines. Transformers located between the two cabs stepped down the 11,000 V to the voltages needed for the traction motors and other electrical equipment on the engine.[3]
Penn Central 4801 and 4800 hauling freight through Elizabeth, New Jersey in December 1975.Twelve 385-horsepower (287 kW) GEA-627-A1 traction motors drove the GG1's six 57-inch (140 cm) diameter driving wheels on three axles using a quill drive. Four unpowered leading/trailing wheels were mounted on each end of the locomotive. Using Whyte notation for steam locomotives, each frame is a 4-6-0 locomotive, which in the Pennsylvania Railroad classification system is a "G". The GG1 is composed of two such frames mounted back to back, 4-6-0+0-6-4. The AAR wheel arrangement is 2-C+C-2 meaning two sets of three powered axles that are hinged together, with two unpowered axles on either side.
