The tank wagon keeps the [[Train|train engine}} cooled. It begins as a vibrant blue and gradually turns red as it heats up. When it is completely red the [[train]] will then catch fire. To keep the tank wagon cool, players must fill the [[Tools|water bucket]] with water, and approach either the tank wagon itself or the train engine. In [[Biomes|biomes]] without air, the water tank instead provides oxygen in a large radius.

The water tank has two upgrades. They both upgrade the capacity of the water tank making it so that it doesn't need to be cooled as often, as well as increasing the radius of oxygen around it.
