PRR Q-1 America's
First Freight Duplex
1942-built Q1 was the PRR's first freight Duplex prototype. It was built with
huge 77" drivers and streamlining.
One of the handsomest streamlined engines built at that time. The
rear pair of cylinders were uniquely mounted alongside the firebox, driving
the rear two pairs of drivers in what looks like, reverse; this is
one of most unique features of the Q-1..
Q-1 Late In 1945
Q-1 was partially destreamlined. The nosecone and side
skirting were removed, although the skyline casing was retained.
The Q1 remained in this form until the end of it's service. It was an even
more exciting locomotive with all its moving parts out for all to see
and admire.. The Q-1 had one of the highest horsepower ratings of any
steam engine of it's time.
