Nope! Not that the GG-1 was a electric locomotive. It drew power from the
overhead lines @11000k 25HZ. Without that overhead power it was stranded, a
240 ton paperweight! It had 30 volts of batteries, kept charged by a rotery
generator, strictlty for control voltages, contactors, headlights, radio,
really it's "acc". battery. It couldn't move on that!
On the same theme, Diesel locomotives are NOT hybrids. The electric in
Diesel elecytric is the transmission of power from the Diesel, known as the
Prime Mover in RR speak, to the wheels, Traction motor on each axle thst
makes it go. Weather it is AC or DC depends where you did your Diseasel
shopping. AC if finding favor BECAUSE Dynamic braking is easier to do with
AC. I get to fly both AC and DC units. The AC is cool, because you put the
power BACK in the overhead lines for somebody else that needs it. DC is
shunted off in resistance grids, for braking power. Helps out the airbrake,
trains' primary braking system.
In mountinous country, out on the left coast, RR's went into
electrification, big time, cheap hydroelectric power, AND the ability to
hold heavy trains back, coming down the mountain, pumping amps back into the
lines, schedules were arranged so the descending train helped the other
train coming UP the mountain. An electrical Funicular RR! Those are popular
in mountains, where two cars are cabled together, when one is up the other
is down. A stationary motor pulls the cars up an down. Only used in short
trips. Be pretty damn inconvenient from Seattle to Portland! A system like
that was used in Providence RI on a steep hill in trolley daze. A descending
the hill car hooked onto a cable, waited for an uphill car, to hook on the
other end. All in place, he POWERED down the hill, helping the upward car
climb the hill. All this from the days that Cast Iron and inginuity overcame
all problems.
