Types of Tank Wagons

Tank wagons are railway freight cars designed to carry liquids, including hazardous materials. They contain cylindrical tanks mounted on a rail car framework. Tank wagons can be classified based on their construction and the type of liquid they transport. Here are some of them:

• Construction-based tank wagon types

  • Pressurized tank car: This tank wagon has a tank that holds liquids under pressure. The pressure keeps the liquid in a constant state. During transportation, your liquid won't change state or become gaseous. These tank cars are used to transport liquids that are hazardous if they become gaseous during the transportation process. Examples of such liquids include propane and butane.

  • Low-pressure tank car: These tank wagon tanks are designed to hold liquids that are hazardous but don't become gaseous easily. They hold the liquids at low pressure, which is slightly above the atmospheric pressure. Since there is no significant difference between the pressure in the tank and the atmospheric pressure, these low-pressure tank cars are more affordable than the pressurized tank cars. They are mainly used to transport chemicals like xylene and toluene.

  • Non-hazardous liquid tank car: The tanks in this wagon hold liquids that aren't hazardous. Since the transported liquids are non-hazardous, the tank doesn't require any special design. The tanks are usually constructed from steel or aluminum to prevent the liquid from contaminating or changing state.

• Content-based tank wagon types

  • Crude oil tank wagon: This tank wagon is designed to transport crude oil. It has large tanks since crude oil is a non-hazardous liquid. The tank wagons are constructed from strong materials to ensure the safe transportation of large amounts of crude oil.

  • Chlorine tank car: This tank wagon is specifically designed to transport chlorine. Since chlorine is a hazardous gas at room temperature, it must be kept in a liquid state using a pressurized and refrigerated tank.

  • GATX tank wagon: This tank wagon is designed and manufactured by GATX Corporation, a company specializing in the leasing of rail tank cars. The GATX tank wagons are customized depending on the client's specifications.
