1218 Feedwater

Tue Feb 26 09:53:11 EST 2019

Bud and Ed,

You are right. My memory was off. Coffin supplied the Emergency (or Auxiliary) feedwater pump. And later they used a Coffin to replace the original Ingersoll-Rand Main feedwater pump that gave so much trouble.

Jawn Henry’s Deaerating Feedwater Heater was manufactured by Cochrane according to Mr. Newton’s authoritative treatise Rails Remembered Vol.4 page 726 and 757. I’m so appreciative that he wrote this excellent work on Jawn Henry.

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?
