S1a and M2 Automatic

[nw-mailing-list at nwhs.org]

The capacities resulted from the designers seeing how big a tender they 
could put on that frame  and still allow clear vision to the back.. 
Incidently, the frame on both tenders under consideration was the same 
one. (from a USRA 12,000 gallon tender) At the time, I think I heard 
someone in Bluefield say an S1a burned 500 pounds an hour, so the 15 ton 
bunker would last 48 hours or more at that rate.  Jim Nichols
