Tony,

HUM!!!??? That just brought up another interesting thought to me. Wouldn't
it be more true to scale-weight then, to know the prototype-car's empty
weight, divide that by the cube of 87.1, (or some other scale ratio) and
weight the car accordingly, rather than per the NMRA tables, eventhough
they're a pretty good, "ball-park" figure?

Only if you want to model empty cars! Then, as pointed out in another
post, mixing widely differing car weights causes problems on the real RR,
and with our exagerated curves and grades, these are multiplied. There
are modelers who compromise somewhere less than NMRA RP weights, often
50-75% of these.
