H21a Hopper PRR #909011 (BOW37774)

From 1911 to 1917, 70-ton H21a "quad" hoppers were introduced for coal service. During 1922 and 1923 all early H21 hoppers were converted to H21a's by replacing the 50-ton trucks with 70-ton trucks equipping them for coal service and bringing the total to 36,000 H21a hopper cars. The original 1909 through 1930 quad hoppers were built with the "old style" double door hopper. During the 1930s and early 1940s, all old style double-door hoppers were replaced with the "saw tooth" hopper, increasing capacity by 39 to 40 cubic feet making them easier to maintain.
