Pennsylvania Railroad 4935
preserved PRR GG1 electric locomotive

Pennsylvania Railroad 4935 is a preserved GG1 class electric locomotive. It is one of sixteen remaining Pennsylvania Railroad class GG1 locomotives, and one of two (along with Pennsylvania Railroad 4800) at the Railroad Museum of Pennsylvania.
History
The Pennsylvania Railroad class GG1 was built to haul longer passenger trains at high speeds, particularly on the Northeast Corridor and the Main Line, during the PRR's massive electrification projects of the 1930s. Constructed in 1943 at Juniata Shops, No. 4935 was among the last of the GG1 series to be built. Like most GG1 locomotives, it was transferred to Penn Central Transportation Company when the PRR merged into Penn Central in 1968, then to Amtrak when it briefly took over intercity passenger service in 1971.
Restoration
In 1976, railfan and United States Department of Transportation economist Howard Serig approached Penn Central about the possibility of restoring a GG1 to its original condition, but Penn Central was not interested. That November, Serig proposed the idea in a column for Trains magazine. A friend of Serig brought the proposal to Amtrak president Paul Reistrup. Reistrup approved the plan on January 18, 1977.
