Jeff,

The info is is a small data book which may be hard to scan or copy.  The drawing with the multiple pages of the data book may be in the NWHS Archives.  If you can remind me prior to the March 12 - 15 Archives work/open house session, I'll see what I can do.

  Gordon -



  Would you be able to share that complete 1951 list?  I'd be very interested to see it.

  Bud,

  In addition to the two named water softening plants in Virginia, we should include Shaffers Crossing in Roanoke--at 5,400,000 gallons per 24 hours, the largest on the N&W in 1951.

  Also, in case someone gets the misimpression that these three softening plants constitute all of the N&W's water treatment plants in Virginia, we could point out that the same 1951 reference lists 24 (by my quick count) "wayside treating plants" in Virginia, in addition to the three water softening plants.

  For some time previously I have toyed with the idea of combining some info that I have on N&W water treatment for its locomotives into an article for The Arrow, where the info would be disseminated more widely, so I'll be interested in any info that anyone can contribute on this subject.

    The tank in Radford was a “standard” design which came in two variations.  One was a 200K variety (like the one in Radford) and the second was 250K.  The difference was the 200K had only one tank for holding either treated or untreated water and the 250K had two tanks – one of 200K for treated water and 50K above holding untreated water.

    There were variations about where the water was treated.  Water could be treated before it enter the tank, in the tank, in the pipe to the stand pipe, at the base of the stand pipe or spout (when water was dispensed directly from the tank to the tender instead of using a stand pope), or even at or near the suction pump at a stream or other source. 

    Now about Radford's tank.  It had only the 200K tank which held raw water pumped from the New River.  The bottom of the tank was more than 20 feet above ground and the water was fed by an outlet pipe to the stand pipe by gravity.  With the tank full, the water level would have been about 50+ feet above ground resulting in plenty of pressure to the standpipe (there is 44 psi for every 100 feet of elevation).  At Radford the water treatment was done at the base of the standpipe.  The tank was at least a hundred yards from the stand pipe.  It probably (but I don’t know) did provide water to the tie treating plant and its three narrow gauge dinkies.  If it did, the water would have to be treated at the tie treating plant.

    The N&W in 1951 listed 17 “water softening plants”.  Two (at Vicker and Glade Spring) were in Virginia and the others were in West Virginia and Ohio.  It also listed 53 “wayside treating plants” which Radford was one.  In my interviews, a number of officials stated that the water in the area of southwestern Virginia was the best water for steam locomotives; although it was relatively hard, it was easily treated.  Water further west and especially in Ohio was the hardest to treat and caused a lot of boiler work because it created a lot scale even after treatment.

    Hope that someone who has knowledge of how water was treated and with what elements/compounds would come forth.  I have some information about proportions of what was used at the wayside treatment plants but I don’t know what the abbreviations mean.  Maybe someone can help on this.

      It appears to me that there would be no water in the structure below the level of the spout; what would be the  point of having to pump it into a tender?  It’s likely that all the space under that height would be empty.

    ​Given the location of the concrete tank in Radford, off on a side track and nowhere near the roundhouse or main line, I'll posit that the tank was a holding tank for raw water pumped from the New River. Once treated by the equipment in the room at the bottom of the tank, the softened water would then be pumped to another tank or tanks, from which tenders would be filled. I assume that the treated water would also be used in the boiler in the power house adjacent to the tie treating plant. Sounds like this could be a good article for The Arrow . . .
