It would seem likely that there would be analogous cases of
freight
cars that are close cousins (we know of the mill gons and the 40's
gons as two examples). The 40 foot cars have been done last year
by
Sunshine. Are there then other cars that would make sense from a
manufacturer point of view...?
Bob is apparently unaware that the AAR Car Construction Committee
took
on the project, just before the US entered WW II, of designating
"recommended practice" freight car designs which represented the
best
current car building practice and had already been built, so that
they
could be quickly ordered into production to meet wartime freight
car
shortages without additional design/tooling. These designs,
adopted in
October, 1941, were all shown in both drawings and photos in the
1943
and 1946 Car Builders' Cyclopedias. They included a 41'6" 50 ton
solid
bottom gondola (built by Bethlehem for the Atlantic Coast Line), a
41'
50 ton drop bottom GS gondola (built by GATC for the Illinois
Central),
a 52'6" 70 ton drop end mill gondola (built by Bethlehem for the
Lehigh
Valley), a 65'6" 70 ton drop end mill gondola (built by GATC for
the
Santa Fe), a 53'6" 50 ton riveted flat car (built by Pullman-
Standard
for the Union Pacific), a 53'6" 70 ton riveted flat car (built by
Greenville for the Erie), and a 50' 70 ton flat car with one piece
cast
steel underframe (the Pennsylvania RR class F30A). No box cars or
hopper cars were designated because AAR standard designs already
existed for these car types.

Within months, the AAR standard and recommended practice designs
were
reworked to employ wood instead of sheet steel for side sheathing,
slope sheets, floor stringers, etc. and became the composite "war
emergency" designs that were built in limited numbers during World
War II. ,snip>

Richard,

Oops. The last paragraph above caused me to reason that perhaps the
Wabash composite gons built in 1944, were the above designs reworked
with wood sides and floors. The 50 ton 41'-6" 13500-14849 series
steel gondolas built by Decatur from 1944 to 1946 were probably
closer to the design of the ACL gons. The Wabash 10 panel gon is
available from Sunshine.
