Pennsylvania RR #4935, an Altoona GG-1, built in 1943
The GG-1 was designed by General Electric using AC current from overhead wires. This class of electric locomotive was first operated in 1935, and hauled passenger cars at 100 mph (160 km/h). The styling of the prototype body shell is attributed to Westinghouse industrial designer Donald Roscoe Dohner and became an early popular symbol of a streamlined locomotive.
Two Penn Central GG1 locomotives pulled Robert F. Kennedy's funeral train on June 8, 1968.
