Koop Steel Artery: Train City Builder - SteamSteel Artery: Train City Builder - Steam

Steel Artery is a train-city building simulator set in a steampunk fantasy world. Your task is to create a thriving city on wheels, where every wagon is a new piece of infrastructure and every decision shapes the lives of thousands of inhabitants.

Once upon a time, the Empire built the legendary Steelpolis, a colossal train that showcased technological power, economic dominance, and authority. It traveled across vast provinces, enforcing order, collecting tribute, and dazzling the masses. But now, the Empire’s treasury is empty, its lands fractured, and its infrastructure on the brink of collapse. To save it, the Emperor revives the abandoned project—and you are appointed as the mayor of this reborn city on rails.

BUILD A CITY ON WHEELS

A living world on wheels

Unlike traditional city-builders, you do not give direct commands. Citizens are autonomous, driven by their own needs and choices. They work, eat, rest, and spend money based on their own choices and circumstances. A worker may refuse a faraway job, quit after earning enough gold, or pick a new profession entirely. You provide opportunities—they shape their lives.

Multiracial colonies

Humans, elves, orcs, and other races bring unique needs and values to your train. They form relationships, carry their own histories, and interact in ways that can foster cooperation or create cultural tension. Managing these diverse communities is as vital as expanding your economy.

Economy and logistics

Every building generates or consumes resources. Workers need salaries, inns charge for rest, and diners demand payment for meals. To keep your city thriving, you must stop in resource-rich regions, extract what you need, and plan your wagon layouts carefully. Space is limited, logistics are complex, and efficiency is the key to survival.

Your city, your story

Will you design a compact, fast-moving train for a tight human colony, or create a sprawling leviathan filled with thousands of inhabitants? Each path offers unique challenges and emergent stories.
