Aluminum has been used for construction of coal railcars and on an experimental basis as a metallized coating over steel railcars. When aluminum is used in areas which contact the lading, resistance to general corrosion has been outstanding. Galvanic corrosion of joints which connect the aluminum to a steel undercarriage has not been a problem provided appropriate measures were taken during vehicle construction. Laboratory test data are presented which illustrate the impact of variations in joint preparation on galvanic corrosion performance. Painting the steel and the use of a sealant are recommended to obtain satisfactory long term joint performance. The corrosion performance and long term durability of an aluminum metallized coating has been demonstrated when applied to new cars constructed of carbon steel. Test results of coating durability when applied to cars constructed of constructed of weathering steel or carbon steel which were in revenue coal service prior to coating have been mixed.
