In 1942, the PRR built an experimental duplex drive freight locomotive, the
Q1, with a 4-6-4-4 wheel arrangement. in 1944, after identifying a number of
flaws with the Q1, the PRR built a second prototype, changing the wheel
arrangement to a 4-4-6-4 and creating class Q2. This was followed by 25
production Q2 steam locomotives in 1945. These rigid-frame four cylinder
locomotives may have been the epitome of superpower steam locomotive design.
At 115,800 lbs of tractive effort and nearly 8,000 horsepower, the Q2s were
the most powerful ten-coupled steam locomotives ever produced. These
monsters were the greyhounds of the PRR, single-handedly hauling tonnage at
high speeds over the PRR's lines.
Mostly seen on the Pennsy west of Pittsburg, these locomotives did venture
east to territory such as Horseshoe Curve and their birthplace, Altoona. The
Q2 was emblematic of the PRR's commitment to on-line coal producers to
continue to use steam locomotives to power their trains after World War II.
However, the Q2 could not match the maintenance records of the invading
diesels and, by 1956, the last Q2 had been retired and scrapped. No example
of this titan of the rails was saved for posterity.
In this production run, we are building a model of the prototype #6131 and
several models of the production version Q2. In addition to the prototypical
decoration, we will also offer unlettered models, a painted brass model, and
two models decorated in PRR-themed fantasy paint schemes.
All of the models have hand-crafted brass boilers, cabs, and tender bodies,
and die cast locomotive and tender chassis. Each model comes with our
Paragon4 Sound/DC/DCC sound system with synchronized puffing smoke and
integral GoPack capacitors.
