Bluford Shops N Scale: 2-Bay Offset Side Hopper - Frisco
Frisco took delivery of this group of hoppers from Mt. Vernon Car in 1948. SLSF generated a surprising amount of coal from regions in eastern Kansas, Oklahoma, and western Arkansas as well as an important deposit in northern Alabama. Much of this coal was interchanged to connecting lines for delivery to steel mills.
A 2-bay hopper design with offset sides was first proposed in the 1920s and first appeared in the form seen here in 1934. The AAR adopted it as a standard design the following year. The offset design permitted greater interior capacity than a rib side car with the same outside dimensions. It was thought this more than made up for the car’s higher cost of construction. The last new 2-bay offset side hoppers were built in 1960.
