Pennsy 6200

Does anyone have the drawing for the drivers for this engine? They where 68" I have to believe they used them on another engine.

Trailing truck drawing would be nice too.

O S Max ( the gas engine/live steam maker) supposedly built one in 1" scale. They might have some prints.

You might check this old thread and see if any of the information is still available.

You should be able to get them from the Pennsylvania state archives at Harrisburgh.

Does anyone have good pictures of the rear and intermediate drivers from Jim K's Berk? They look similar

Attached is a photo showing the Berkshire un-machined driver castings.
I think the intermediate and front driver would be the most appropriate since the rear driver had the protuding counterweight and crankpin boss for the rear tandem main rod.
These ductile iron castings are 1.5' scale, 69" driver, and therefore finish to 8-5/8" diameter at the tire.

The prototype 6200 had 68" driver, and I think that they were 15 spoke drivers. The Berkshire also had 15 spokes.

I have always thought that this would make for a fascinating model. What other 68" driver eight coupled locomotive is 7 to 8 feet longer than a typical 80" driver northern?
Pennsy had a really interesting steam to Diesel transition era.
