O Wolf’s Head Oil Triple Dome Tank Car

Product Copy: Three-dometank cars were actually three complete tanks on a single car body. Eachtank had its own end bulkheads and expansion dome. Since older tankcars were filled to the top of the tank to prevent fluids from sloshingaround during shipment (which could make the car unsteady), the domesprovided space for the cargo to expand when the sun heated the tank.Because the additional bulkheads and domes added weight, multiple-domecars had a smaller capacity than single-dome cars.
These cars were popular with customers who needed several varieties ofa single product, such as different grades of lube oil or gasoline.They were also used for customers who did not need a full car ofproduct. While smaller-volume shipments have largely gone over totruckers today, Union Tank Car built new multiple-compartment cars asrecently as 2010. They’re harder to spot in today’s trains, however,because modern tank cars do not have expansion domes.
