6-4-4-6 Pennsylvania Steam Locomotive

6-4-4-6 S1

The Pennsylvania S1, a 6-4-4-6 duplex, as a one-of-a-kind experimental locomotive that was a big hit at the 1939 World's Fair in New York City, where it was displayed in operation on rollers.  The streamlining was designed by the noted industrial designer Raymond Loewy, who also designed the GG1.  Due to it's size, it was restricted to operation on the western portion of the Pennsy, it had slipping problems, and did not last long in service.  In July of 2003, MTH brought out a full-scale model of the S1 in their Premier line. As you can see in the following photographs, it's a superb model.  What the photos don't show very well is that this model is a full 36 inches in length!!  The first shows the entire behemoth in a side view.

The next shows the front end and nose of the model.  If you click on the photo, you can see it in its full 6.5 megapixel glory.

The next photo shows the backhead as viewed from the sliding roof hatch -- note the valve handles and gauges.

The next photo shows the enormous tender.

The next shows the locomotive.

The final photo shows a little of what goes on as this monster CHUFF!s and PUFF!s its way down the tracks.
