The Mighty PRR S1

In June of 2003, MTH brought out a Premier model of the Pennsylvania RR (PRR) S1, which was a one-of-a-kind 6-4-4-6 duplex steam locomotive. Unlike the big articulated locomotives, this one had a solid frame.  The prototype locomotive spent the first two years of its life on rollers at the 1939 New York World's Fair, where it wowed visitors. In actual service however, it was too big for the tight curves of the east and spent it's short life running west of Crestline, Ohio, where it proved to lack sufficient traction to justify its existence, hence it was the only one of its kind.  The model looks great (it reminds me of Flash Gordon's spaceship from the old serials), runs great, and sounds great. In this True HD 1080p video, you see it hauling a total of 18(!) heavyweight passenger cars, a very, very heavy train indeed. With just about any other locomotive, I'd double-head to pull this load; the S1 manages it all by itself.  Truly, a mighty locomotive!
