These PS-2 70 ton 2-Bay covered hoppers are painted light gray with black lettering. It was built in 1969, serviced in 1978 and runs on roller bearing trucks. The principle commodities handled by these hoppers are cement, sand, potash, soda ash, lime, alumina, fertilizers, dolomite, soap, salt, plastic pellets and flour. Since many of these materials were highly corrosive, the PS-2 was designed to withstand their inherent effects and keep maintenance regulations to a minimum.
