in North Freedom, Wisconsin .]] A tank car is a piece of Railroad Rolling Stock designed to carry liquefied loads. Many variants exist due to the wide variety of liquids that can be transported. Tank cars can be insulated or non-insulated, pressurized or non-pressurized, and designed for single or multiple loads. Non-pressurized cars have plumbing at the bottom for unloading, and may have an access port and a dome, housing various valving on the top. Pressurized cars have a pressure plate, with all valving, and a protective cylindrical housing (dome) at the top. Loading and unloading are done through this opening. Insulated cars (which may also incorporate heating or refrigeration systems) are used when the contents must be kept at a certain temperature. For example, the Linde tank car depicted below carries liquified Argon . Cars designed for multiple loads have internal bulkheads to separate the contents. Each compartment must have separate plumbing and its own dome if so equipped. The added complexity of multiple-load cars means that they make up a small percentage of the tank car population. If two loads must be transported, it is often simpler to use two tank cars instead of a two-load car. In some countries, such as the United Kingdom , Ireland , and New Zealand , tank cars are called cylinder wagons or '''tank wagons'''. HISTORY |
