Running a GG-1
By Pierce Haviland
|By the time I had the chance to run the GG-1 in the 1970s,
they were already nearly 40 years old. Despite their age, the GGs were
very dependable. They had to be. Maintenance during the Penn-Central era
was nearly non-existent.
The throttle on the GG-1 had 22 notches. There were three ammeters that
indicated the power going to the traction motors. Engineers had to be
careful not to pull too much power. An overload breaker on the engine
would trip, or auxiliary systems would shut down.
