The present invention includes a system for storing and transporting a liquid in which a series of tank cars each have a hollow tank body with an inlet and an outlet supported on a frame with a plurality of wheels on the frame. In one embodiment, these cars are connected together with a sealable male fitting and female fitting which interengage to allow fluid flow between the cars.
