1218 Feedwater

Gordon - 

Add my name to those envying you your Juan Henry ride!

In everything I’ve heard and read about it, including Louis Newton’s excellent observations, I come to the conclusion that the only part of it that really worked well was the boiler.  In the days before traction alternators (EMD’s AR-10, for instance), it didn’t work well trying to pull 4500 HP out of a DC generator of a size that would fit on a locomotive – someone told me that grounds blew holes in the commutator big enough to hide a softball in.  The peripheral pains in the rear end just helped doom it. 

How far off base am I with this observation?

Gordon,

Failed trip or not I envy your ride in the 2300! 

Just think if it had been a useful engine having a fleet of them running around the N&W.

When I was doing shift work at the Shaffers Crossing roundhouse the summer of 1956 and got off the third shift one morning, I learned that the 2300 had been called for a Blue Ridge pusher, so I took advantage of this opportunity and my pass which had the inscription "good on engines and freight trains," and hopped aboard.  My rest could wait!  As we pushed a freight train up the Blue Ridge grade the main water pump went out and the emergency pump had to be placed in service.  After that one push, we returned to the roundhouse for repairs.  A not-too-unusual routine for Big Jawn.

I also remember another occasion when the loco was on the roundhouse turntable and one of the shopmen saw it there and remarked, "Is that thing in here again?"

  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?
