31,000 Gallon Tank Car

Prototype Information

Since 2012, TrinityRail has built thousands of 31,000 Gallon Tank Cars with head shields to meet the growing demands of the oil industry. This Trinity tank car is easy recognizable by its unique trapezoid-shaped end shields.

Mile-long unit trains with 100+ cars crisscross the United States and Canada daily to deliver crude from the oil fields of North Dakota, Wyoming and Montana to refineries on the East, Gulf and West Coasts.

As demand for shipping crude oil by rail has declined, these cars are now carrying ethanol, gasoline, petroleum distillates, and other commodities. In addition, these cars can often be found in mixed freight trains.
