Title: scale weight
Post by: full maxx on November 25, 2009, 06:01:12 PM
how does one go about figuring the correct weight for model trains to be correct in scale compared to their 1:1 counterpart

Dear FM,

Cube of the scale times the prototype weight,  though I think the NMRA formula for model train car weight is much different than that.  (See nmra.org)

For example, HO = 1:87, cubed = 1/87 times 1/87 times 1/87 = 1/658503

80 tons = 160,000 lbs = 2,560,000 oz. , times 1/658503 = 3.9 oz. 

Hope this helps. 

Sincerely,

Joe Satnik

one last question...where do you get scales to weigh your engines and cars to be accurate or how do you know the purchase weight of you engines and cars

Bought a used postal scale at a garage sale about 40 years ago.  Accurate enough for weighting cars.

Or you can a postal scale, Wal-mart, office depot, etc have them.
