ABSTRACT:
A railway hopper car comprises one or more gates, which have a durable, abrasion-resistant, low-friction coating applied to the upper, load-contacting surface thereof to reduce breakaway opening torque. The railway hopper car is particularly useful in handling heavy loads of bulk materials which have high densities and which compact under load, such as soya meal and hydrated alumina. The preferred coating use on the gate is a polymeric powder paint coating having high impact resistance, as well as high abrasion resistance, at the temperature extremes that may be experienced in the harsh operating environments typically encountered by railway hopper cars. The preferred coating is a food grade material suitable for use in contact with bulk agricultural commodities.
