Prototype History: Liquefied Petroleum Gas (LPG) (also called Autogas) is a liquefied mixture of propane and butane. It is an inevitable by-product of the crude oil refining process and of natural gas processing. In natural gas processing, the natural gas is cleaned off heavy hydrocarbons such as propane and butane before distribution. About 60% of global LP Gas supply comes from natural gas processing. In crude oil refining, LPG is a by-product of the refining process. LPG is gaseous at room temperature and changes to a liquid when compressed at moderate pressure or chilled. The chemical composition of LPG can vary, but is usually made up of butane and propane with a 30-99% propane mix.

The 33,900 gallon tank car is one of the largest standard tank cars used today. While Liquefied Petroleum Gas (LPG) and Anhydrous Ammonia are the two most common commodities, they are also used to transport butadiene, isoprene and gasoline. These cars can be seen regularly in mixed manifest freight trains throughout North America. They travel singly or in large blocks between producers and distributors.
