> I don't have any information as to whether it helped or not.
Jim,
     Again, /"You can read about it in the N&WHS Newsletter Vol.6, No. 
1, Jan. - Feb. 1990."
/I think the practice first started in England as I have read of it 
being used on the "Saint" Class 4-6-0 locos around 1902. While the exact 
appliance may not have survived, the principle did, in that it did help 
preheat the water entering the boiler. And, it must have worked well 
enough that the N&W went almost exclusively to top mount check valves.
