Jamie... How in the world did 48,000 pounds get translated into 2.93 ounces? Just out of curiosity, how can the weight of the prototype be reduced to an equivalent weight of a model? Not sure how that can be done. But, just for the heck of it, if the 48,000 pound boxcar has eight wheels, then each prototype wheel presses onto the rail with 6,000 pounds of force. Obviously, our models don't have that kind of weight. So let's divide by 64 (S=1:64) and then each model wheel should press onto the rail with 93 pounds of force. H-m-m-m-m- m....that's not quite right either. OK, let's try the volume calculation: 64x64x64=16,384. So our model wheel force should be 6,000 divided by 16,384 which equates to .366 pounds. Eight wheels times .366 pounds equals 2.93 POUNDS!! We at least have the same number but I think POUNDS is more correct than OUNCES. (At least I hope so or I am really going to be embarrased.) Since we don't have boxcars in S scale that weigh in at nearly 3 pounds, I think it is true that our toy trains are "very lightweight" compared to the prototype. Any other mathematicians out there?
