Pollux is a unique cargo engine that players can unlock and upgrade entirely for free—simply by watching ads. Although it starts out small, it can become a powerful addition to your train fleet if upgraded regularly.
How to Unlock Pollux
Pollux is unlocked automatically after watching your first bonus video (the second video you see after initiating one). Once unlocked, it becomes available on that game world.
The engine is tied to the current game world.
You must unlock it anew on each game world you play.
It resets after each round and does not carry over like your Career Engine.
Starting Stats (Era 1)
Tractive force: 1

Max. speed: 50 km/h

Upgrading Pollux
You can improve Pollux by watching bonus videos. The number of upgrades you can earn each day depends on the game world's speed:
1x speed – 1 upgrade/day from the first 14 bonus videos
2x speed – 2 upgrades/day from the first 14 bonus videos
4x speed – 4 upgrades/day from the first 16 bonus videos
The Clutch Upgrade always comes first in each new era. It enables Pollux to transport goods from that era. If you're in a later era, you'll first receive the missing clutches before any other upgrades.
Good to Know
Pollux always resets on new game worlds.
It does not retain upgrades like your Career Engine.
The more videos you watch, the more powerful Pollux becomes.
It’s a great free boost—especially if used consistently.
