There were 1500 cars in the 55950-57449
series (SM-18 and SM-18A) but the
Burlington didn’t have that many dump cars through its entire
history. Prior to the start of class numbers, there were about 215 cars
built between about 1891 and 1902. Then there were five classes of dump
cars with a total of 523 cars (possibly including some of the pre-1910 cars) Also,
there were no ballast cars built in 1914 and even the earliest ones were still
in use in 1926-28 (in case there was confusion between dump and ballast cars).
However, looking at gondolas, I may have the answer. I think “National
dump cars” should read “National Dump cars”.
All-steel gondolas GA-10, GA-11, GA-12, GA-13 and GE-2 were all built with
National Dump rigging. GA-10 and GA-11 were built in 1913 while the other
three groups - GA-12 (182000-183149), GA-13 (183150-183249) and GE-2 (179700-180199)
were built in 1914 by Haskell & Barker. GA-12 and GE-2 cars were
constructed to the same plan. All three groups had drop bottoms, the
difference being the GA’s had fixed ends while the GE’s had drop
ends.
Looking at the ORER’s, the number of cars in these three classes reduced
only slightly between 1918 and 1925 when there was a sudden drop from 1512 cars
in 1925 to none in 1928. Similarly, the numbers of GA-10 and GA-11 cars dropped
from 3162 cars in 1925 to nil in 1928. These sudden reductions are certainly
not typical of natural retirements, wrecks, etc. Even allowing for the
cars that were converted to GS-3 in 1923-1926, there would appear to be plenty of
steel centre sills available in 1926-1928 for the SM-18/A stock cars.
I wonder if there was a glut of gondolas in 1926 to justify scrapping these
cars when cars built before them were kept in service.
