If I have a car who's tare weight is 50,000 lb. and I loadSure, as I said, Pat, the operating guys bought into this. Some did say, as you can read in Railway Age, that rolling resistance was not a strong enough function of weight to make it worth saving a few hundred pounds. The real point was, how did you achieve the saving? and what did it cost?
Also, most of the RME and RA articles on new car designs usually specified the light weightSure, everything else being equal. The question which isn't so easy is, what if lighter is achieved by using a material that corrodes easier? or is thinner and requires extra posts in construction? The mere fact that the burst of "lightweight" box cars after WW II soon died out ought to tell you something. OTOH, of course everyone bought into welded underframes, which save a bunch of weight. I simply dispute the notion that everything to save weight was good.
By the way, ads often state the obvious - Wonder Bras do wonderful things!!!!No argument, but they also may state unessential things; and they certainly often state things they wish you would believe.
