In the early 1980’s sodium chlorate began to replace chlorine as a bleaching agent in the paper
making process. Historically, sodium chlorate had been transported in solution form in tank cars.
With significant increase in demand, a more efficient delivery method was needed. Transportation
in crystal form by covered hopper car was a natural solution. However, a means to address the
corrosive properties of sodium chlorate was required.

Procor took on the challenge to come up with an alternative and went on to develop an all-
aluminum construction covered hopper car. Parallel in concept to the aluminum bodied wheat
board covered hopper previously built by National Steel Car (NSC), the Procor engineered car
incorporated two fundamental design changes; lower cubic volume, due to higher commodity
density (3,000 cu. ft. compared to 4,100 cu. ft.) and upgrade from 70 ton (220,000 lb Gross Rail
Load) to 100 ton (263,000 lb Gross Rail Load).

Over the years Procor would assemble a fleet of more than 1,300 aluminum sodium chlorate
service covered hopper cars, a portion of which was constructed by NSC and Thrall. The Rapido
version is representative of later production cars fitted with steel gull wing end structures.
