Tank cars are used to transport a variety of liquids and gases. Some tank cars are lined with special materials. Food-service tank cars may be lined with stainless steel, glass, or plastic. Cars for chemical transport may be lined with steel, rubber or other special materials that do not react with the chemicals the car carries.
Tank cars can be pressurized or non-pressurized, some are insulated and some have multiple compartments so they can carry more than one kind of material.
