tanker car (rail)
(rail transportation) A tank integrated into a railroad car frame designed to carry bulk liquids by rail. Common commodities transported in tankers include refined gasoline, heating oil, alcohol, industrial chemicals, acids (sulfuric acid, oleum, phosphoric acid, hydrochloric acid, ferric chloride, hydrofluosilic acid), clay slurry, and corn syrup and other foodstuffs. Tankers are manufactured with product-specific linings and coatings to protect tank shell integrity and product purity. Many cars are fitted with loading and unloading devices on a single nozzle, protecting workers and the environment. Acid cars are specially designed and constructed tankers that feature high-bake epoxy linings, acid-resistant coatings, and acid-resistant fittings and unloading systems.
