I have noticed the 783 is being rebuilt with an A-Frame design. I am not familiar with this configuration so I have been researching A-Frames.
I found that In 1904 the National Car Company built 100 of the 800 series, a Class 18, 12-ton drop-bottom gondola, to haul 25 tons. Drop-bottom gondolas carried bulk material such as ore, coal, coke, sand, ballast, and rock.
I have not found any historical records of the Drop Bottoms rebuilt with an A-Frame as shown in this Friends of the C&TS photo. What am I missing?
Thanks,
Kevin
