Tank Wagon

Level 1

Level 2

Level 3

Basic starting train when playing endless. from left to right: Crafter, Storage, Tank, Standard steam engine.

Both the tank wagon and the bucket will be filled up when it's raining.

The tank wagon keeps the train engine cooled. It is 1 of the 3 essential starting wagons that generate upon starting a game. The function of a tank wagon depends on the biome.

In biomes with air, a full tank begins as a vibrant blue and gradually turns red as it heats up. To keep the tank wagon cool, players must fill the water bucket with water and approach either the tank wagon itself or the train engine. When the tank is completely red, the train will then catch on fire. The fire will spread to nearby wagons, making them cease functioning until the fire is put out. The tank is also cooled down by rain.

In biomes without air, the water tank instead provides oxygen in a large radius.

A tank wagon can be upgraded twice in Endless game mode. If players upgrade this wagon, the next iteration will yield a higher capacity 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.

Endless Strategy

Swapping the crafting wagon and the tank wagon after the first station is recommended, due to the importance of tracks and because then the train can be cooled down at the front and at the back.

Bringing the tank wagon forward for biomes without air will help with oxygen management.

Moving the Tank to the front/back is possible within the shop. Simply pickup the Tank and drop it in place of the chosen wagon once you connect your train to the first station.
