1218 Feedwater

This was certainly a big problem.  Other problems were the turbine and generator leading to its demise among other things.

I think this was one of the most troublesome items on the JH. If this had been resolved who knows what might have developed. A series build of JH clones perhaps?

Jawn Henry’s locmotive diagram does not list a feedwater heater per se.  It lists a “feedwater pump – Ingersoll-Rand and Coffin”.

I don’t remember offhand, but you’re probably right.  I forgot.  You never say never . . .

Ed, Seems like I remember NW used a Coffin on the Jawn Henry and it was problematic to say the least. Pls correct if mistaken.  Thx, John Garner

Mike - 

The A class engines used a Worthington 6-SA feedwater heater system.  There was a turbine pump under the left side of the cab to provide the cold water and there was a hot water pump under the left running board at its forward end.

All the Js and the Y-6bs used Worthington SA systems.  N&W had hundreds of engines equipped with the earlier Worthington BL feedwater heaters, which appeared under the left running board and incorporated the pump and heater in one casing.  The Worthington systems were very efficient and dependable and, AFAIK, N&W never used feedwater heater systems from any other manufacturer (Elesco, Coffin, etc.) nor did it feel it necessary to build its own.

In this topside view of 1218 can be seen what I assume is the feedwater heater forward of the stack. Was this an in-house design or a product of an outside manufacturer?
