The GG1, one of the PRR's most famous and recognizable locomotives, is also
one of the most curiously designed. Technically two locomotives under one
shell (a "G" class locomotive is a 4-6-0 by PRR specification, therefore the
GG1 was two "G" locomotives in a 4-6-0:0-6-4 arrangement). This added up to
a 4.6k horsepower locomotive that was staggeringly powerful, even by today's
standards. Designed in the 20's, built in 30's, and not retired until the
80's, the GG1 had an incredible lifespan (even when they were cut in two and
run as GGÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃý's) and survives today as a testament to its time in both its
unique Loewy-design and overwhelming performance.

Amtrak and Penn Central: Thanks to the long life and usefulness of
the GG1, many outlived the PRR, finding themselves in Penn Central - and
later in their life, Amtrak - paint. These locomotives were used in
everything from freight service to pulling Amtrak Passenger trains.
