 First introduced in 1940's, built throughout 1950's and operated well in to 1980's, this hopper is one of the most popular non-boxcar pieces of equipment to roll on North American rails.
 These versatile hoppers were used to transport granular bulk commodities, such as sand, concrete, powdered lime, sugar.
Some are still in service today, primarily as Maintenance of Way (MOW) service.
