Another obscure question about Espee steamers: Would anyone know what the cab markings on a P-4 might be and what they mean? These are the little alphanumeric codes at the bottom of the cab below the road number, e.g. "P-77 22/20 141-S" for a P-5. By knowing their meaning, perhaps one could extrapolate them for a specific type of loco. Thanks.

Ok, this is from memory:) Pacific, 77 inch drivers, cylinder dimensions, S for superheater.
The 141 Im not to sure, I want to say boiler pressure.

That's JUST what I was looking for! Many thanks, and may your bearings never seize and your fires never flare back! 141 PSI does sound a bit low (my old Navy ship with recips steamed at 250 psi, and that was with saturated, not superheated steam), but I can accept it. Thanks again. |

Just picked up a set of super premium HO scale Espee steam loco decals authenticated by Espee historian Charles H. Givens. According to the information sheet included with the decals, the "141" of the P-4 cab markings indicates "weight on drivers". I don't know if it's in tons or thousands of pounds, or if it's the weight on each individual driver, or all six, but there it is. Thank you Mr. Givens. |
