More on Flexible Beam Locomotives

Recently John Ott completed another fantastic drawing of a flexible beam locomotive to add to his collection of early locomotive drawings. If you haven't seen his work, then please check this website, a sample of which is at the right.
The new drawing depicts the engine  Iron City.

I asked if John could do a version of the drawing showing the flexible beam 0-8-0 engine Washington, as used on the USMRR Aquia Line. John quite correctly pointed out to me that the Washington was likely an older and smaller design. He would need to do more research before he could do a proper drawing.

I have never seen a drawing or photo of the Washington. So I contacted my friend Nick Fry, curator at the  John W. Barriger III National Railroad Library  and Vice President-Operations, BORRHS
for help. Sure enough he hit pay dirt. He sent me this scan of by Edward Wiswesser's book,  "Steam Locomotives of the Reading and P&R Railroads."  Nick believes  that the USMRR Washington was probably of the same class as the Baldwin built P&R Pocahontas, which is similar to the Princeton in the photo below. Although a flexible beam locomotive, it is quite up-to date in appearance for an ante-bellum locomotive.  I suppose the loco had a standard tender behind it.  Such a loco would make a good scratch building project for me.
