The tank wagon keeps the engine cooled. It begins as a vibrant blue and gradually turns into red. 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.
