Penn Central Transportation Company
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, #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 took over intercity passenger service in 1971.
