About the Game
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.
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.

Official update history
Wow… seriously, wow. I’m genuinely overwhelmed by the amount of support and warmth in your messages. It became the fuel I needed to continue this difficult journey (instead of coal and dirty water ^_^).
I think I’ve fixed everything that was broken — and even improved a few things. I didn’t have enough time to test all of it super thoroughly, so I still assume there may be issues left. The current update should be compatible with old saves, though as always, something may still go wrong — and if it does, I’ll definitely do my best to fix it once you let me know.
In the comments, please share your impressions of the current build — does it feel better now?
And if you’re too lazy to read the changelog — don’t leave just yet, because at the end I also talk a bit about what’s coming next.
Changelog 1.0.6:
Fixed logistics and made it smarter — smarter task “bundles” are now used. For example, a carrier can now pick up construction resources for several structural blocks at once and service them all within a single task.
Improved optimization by speeding up pathfinding.
Changed the internal game versioning system — future updates are now compatible with old save files.
Buildings now display which resources will be recovered before demolition.
Hovering over storage now shows the amount of resources inside without needing to click on it.
Fixed the incorrect elf icon on the global map.
Added the ability to change the maximum construction height for chassis in the game template settings.
Fixed the inability to remove the last Chassis I.
Frames can now all be selected for demolition — they will patiently wait their turn in the dismantling queue.
Fixed an issue where a creature could disappear if it was outside during an expedition while its workplace was destroyed/frozen. If a creature outside now goes missing, you immediately see it.
Fixed an issue with cached statistics — resource information in the UI should now always display correctly.
Wealthy creatures have become kinder and now quit their jobs immediately instead of occupying workplaces indefinitely.
Removed the hidden “rationality” mechanic for creatures — previously they could choose either the best or second-best option. Now they always choose the best option.
Crashes during game loading were caused by weak GPUs and my own stupidity, because I used PNG textures that became uncompressed when uploaded to the GPU, increasing VRAM usage by 10x or more. Textures are now stored in a more GPU-friendly format.
New buildings are now locked during the tutorial to remove the temptation to rush ahead too early.
Added a “Skip Tutorial” button for players who want to discover the art of being a Mayor on their own.
Fixed route generation issues on large global maps (caused by a small overflow bug).
Also fixed an annoying issue with simulation “drifting” at high game speeds on weaker CPUs. The simulation could accumulate lag debt because it was falling behind, eventually leading to complete paralysis.
Corpses and waste can now be carried directly to the furnace without requiring intermediate storage.
When will the content update arrive, and what will it include?:
I already planned the next major content update. Here’s what to expect:
hand-drawn cities for all regions connected by railway
generation of endless side quests
ability to throw resources outside the train + reputation systems with new factions (these two features may end up connected :D)
a trading system tied to your reputation, regional needs, and available regions resources
commercial transportation (I can already picture a gigantic container full of chickens racing through the desert!)
a small standalone story scenario with some moral message behind it (not fully sure yet, but I’ll try)
With this update, I want to finally fulfill my “debt” regarding trading and proper city visuals, while also adding a new gameplay layer where you can roleplay as a trading caravan focused entirely on business, spending gold on your needs while completely ignoring production chains.
You’ll probably ask: “So when?”
And my answer is: 2–4 months, because drawing the cities is by far the heaviest task in every possible sense, and we’ve already started working on it.
What’s coming in the near future? Several new patches:
While waiting for the city artwork to be completed, the upcoming patches will focus on QoL improvements, UI, improving existing systems, and polishing balance in order to smooth out the experience for new players and recover the game’s approval rating as quickly as possible. I’ll try to release these patches roughly once per week.
The core realization is this: the game currently does not teach players how to actually play well, nor does it provide enough tools to understand and prevent problems. I’ll talk more about this in my next post. There are also several frustrating mechanics that I want to improve. One of them is giving players finer control over overproduction, so you won’t have to deal with tedious building-freezing micromanagement anymore.
Somewhere between these patches, I’ll also organize my backlog of ideas and finally share the roadmap.
And also keep sharing your wishes regarding changes to the current game. I know many of you already wrote about these things in discussions, reviews, Discord and other places, but if you emphasize again in the comments what matters most to you, it will help me better understand the importance of those requests.
Huge thanks to everyone who believed in me!

Hello everyone,
This is the message I’ve been waiting a long time to write.
Steel Artery: Train City Builder is now available on Steam.
What started as an idea for a moving city builder eventually became Steelpolis: a living train-city filled with autonomous citizens, production chains, logistical headaches, social tension, and the kind of emergent chaos that only happens when thousands of independent agents are all trying to live their own lives at once.

For those of you who have followed development, shared feedback, wishlisted the game, or simply kept an eye on this strange train project over the years, thank you. Reaching launch is something I couldn’t have done without that support.
[img src="{STEAM_CLAN_IMAGE}/45550046/94c71aed850d12d7c57627bf55aa74bd7bae7d51.gif"]
And for those just discovering Steel Artery today, welcome aboard.
If you’ve been waiting to jump in, now’s the time.
And one important request:
If you play Steel Artery and enjoy your time with it, please consider leaving a Steam review.
Reviews make a huge difference for indie games. They help other players figure out whether the game is something they’d enjoy, and they also help Steam understand that the game should be shown to more people. Early reviews especially can have a real impact.
If Steel Artery turns out to be your kind of game, your words genuinely help.
Thank you again for being here.
See you aboard,
SoulAge23
