| Chicago Burlington & Quincy Railroad Class LO-10 184715 at Perham, Minnesota on an unknown day in August 1979, Kodachrome by unknown photographer, Chuck Zeiler collection. This car was one of 350 Class LO-10 cars built by Pullman-Standard in 1967 ( at the P-S Butler, PA plant ), numbered 184600 - 184949 ( later, BN 457000 - 457349 ). The following is from Burlington Route Historical Society's Bulletin 20, COVERED HOPPERS, edited by Hol Wagner: During 1967 and 1968, the largest group of Pullman-Standard covered hoppers joined the Q roster in three separate orders totaling 575 cars. These big 4,740 cubic-foot capacity grain cars were of a new design featuring "high" sides ( actually shallow sides with a deep bottom edge higher than normal ), very deep hoppers with the center sill passing through them, and center discharge outlets. Trough hatches had quickly become standard on grain cars, and these Class LO-10 and LO-10A cars featured lightweight four-section fiberglass loading hatches. Built after the 1967 AAR rule changes regarding non-essential rooftop running boards and the consequent positioning of hand brake wheels, these cars had low-mounted brake wheels. All but 50 of the 575 LO-10's had straight gravity discharge outlets of either the Enterprise or Fabko variety; cars 184925 - 184949 featured Enterprise Gravac vacuum-assisted gravity outlets. |
