 Hi I see your modeling western new york very nice, me too Pittsburgh,Ohio & New York (PO&NY) with a terminus at binghamton. Cool

Anyways the capacity was rounded off to the nearest 1000 lbs. and the load LD LMT would be to the nearest 100 lbs thus your would have a not so nice even no. for your load limit and an nice even one for CAPY. 1925 era would mean most of your labeling would handle 50 ton or 55ton loads (100,000 - 110,000) there were USRA coal hopper that were 55ton hoppers with panel sides instead of the offset hopper if want to use them, and as you know most USRA standard equip. was widely used and adopted by many railroads.

 OK, Duh...... Went back and read the posts again.  I got it now.  So there is no problem with the weights as listed on my cars.  I am modeling the period just after the USRA, 1925.

Thanks!

Loaded to CAPY the Gross Weight would be 121,000. Loaded to LD LMT the Gross Weight would be 136,000

So, in the example I cited, shouldn't the Capacity then be 54000?

Capacity is what the car is supposed to carry.  Load limit is the max the car can safely carry.  Light weight is what the car itself weighs.  If the car is carrying more than the load limit it needs to be mechanically inspected before it is safe to move.  The gross wirght (not listed on the car) is the sum of the lt weight and capacity.  According to AAR rules the capacity cannot exceed the load limit.

When you weigh a car, you get the gross weight, you subtract the tare weight (LT WT) to get the net weight.  The net weight cannot exceed the LD LMT.

 A quick question for you folks.

I am in the process of printing up some decals for my fictional line and just happened to notice that the information printed on the side of my cars (RTR ones) don't seem to jive.  For instance:

CAPY       80000

LD LMT     95000

LT WT      41000

It would seem to me that the LT WT + CAPY should = LD LMT?  Can someone explain the numbering system to me as I want to make sure I have it reasonably right on my decals.

Thanks in advance!
