Tank Car, Single Dome, 56 Foot

History: Larger 50+ foot yank cars replaced their smaller predecessors in the late 1960s and 1970s. One example is the class DOT 111 A100. This car is rated for non-pressurized use with a safe maximum operating pressure of 100 psi. Developments in materials and manufacturing allowed this tanker to be constructed without an underframe. The bottom of the tank itself serves as the load bearing structure. The primary difference between the various types of DOT 111 A100 class tank cars is internal with varying types of insulation, lining and even weld material. Cars of this type haul a wide variety of commodities such as gasoline, vegetable oils, corn syrup, fruit juice and weed killers.
