Maybe the first RR to equip a gondola with a
removable roof was the B&O in 1936.

At that time The B&O converted two of there
O-41 50-ton 49+ foot cars to class O-41A.

They were changed back to O-41s 8-20-42.
Another B&O innovation that was before its time.

There was an article in the Model Craftsman (RMC)
magazine of November 1940 about these cars with
one picture and a sketch of the Detachable Car
Roof Details. This made it a waterproof seal.

Another invention of John J. Tatum, Assistant
Chief of Motive Power & Equipment of the
Baltimore & Ohio Railroad.

The B&O did not follow up on this until 1957
when they converted some O-63 class 52'-5"
with covers to carry bar steel reclassed O-63E.
25 cars.

And also in 1956-57 they converted some more
O-63s to O-63D by adding corrugated steel covers
to carry coiled steel. 224 cars were converted
at their DuBois, Pa. shops.

And again in 1959 they converted 140 O-65 class
52'-6" gons to class O-65A this time using
Republic Steel Corp. Hoods.

And some more O-65s (50) to O-65C in 1957
using Std. Rwy. Equipt. Co. removeable roofs
for bar steel loading. 70 Ton cars.

And more to O-65D in 1957 (10) using Youngstown
removeable roofs. These were for Tin Plate and
rated at 70 Ton.

And some more in the 60's out of scope for this list.
ECK.
