Congrats Ben, quite a railcar to mod...!
Ben, here is another page from
The Ohio State Engineer, by A. H. Dierker, 1926.
The light weight of this car is 78,000lb(35.38mt)..
This, along with my previous post-link should give you dimensions on this car.
I was common to see VGA strings of cars on N&W rails, if the customer specified VGA as the principal source of transport...provided the motive power was there to pull such a train. The train of 100 of these(they had 2,000 at this time), was 5,300ft(1.66km) long, weighed 16,000 tons(14514.68mt) & required a 2-10-10-2 Mallet weighing 893,000lb. with a tractive effort of 147,000lb.
It ran about 25mph.
So the need for electric powered locomotives was an absolute necessity, In my informed opinion...
From
Apalachian Railroad Hopper History..."in 1914, the N&W jumped straight to 90-ton "battleship" coal gons (NOT hoppers) in 1914, and Virginians first 120-ton battleship gons came in 1917."
