Train Sim is now available on Steam for Windows PC.
After years of building Train Sim for mobile players, you can now experience the game on PC -with 80+ trains, 16 environments, Creative Mode, and more.
Drive steam, diesel, electric, passenger, freight, subway, and high-speed trains. Explore hand-built environments, switch between different weather and times of day, operate passenger and freight trains, or simply sit back and watch the trains go by.
And if you’d rather build than drive, Creative Mode lets you create your own railway environments.
A train game you can enjoy at your own pace
Train Sim has always been about giving players the freedom to enjoy trains their own way. Now that experience is available on Steam too.
Thank you to everyone who has played Train Sim over the years and helped us get here. What started as a small project has grown into a game played by millions of people around the world – and we’re still adding to it.
Over the last year, Train Sim had 9 official releases, along with a steady stream of beta updates and behind-the-scenes work.
A release can make development look simple: add a feature, publish a version, move on to the next one. The reality is messier-and, I think, more interesting. Keeping an indie game moving forward means balancing new content with bug fixes, technical cleanup, platform work, and all the small improvements that make the game feel better over time.
The year in numbers
During the past year, Train Sim development included:
9 official releases
126 commits
More than 700 file changes
More than 100,000 lines changed
Those numbers do not tell the whole story, but they do show that a live game is never just “finished.” Even a small update can touch menus, game systems, visuals, testing, store builds, and fixes for issues players may never see.
What players saw
The visible part of the year included new locomotives such as the ČSD Class 754, British Class 360, and Peckett 0-4-0ST, plus a new Austria–Czech Republic themed level. There were also larger improvements to how the game works: multiplayer leaderboards, train filtering, vehicle crashes, better track switching, and updates to steam effects and the interface. Those are the changes that are easiest to point to, because they give players something new to explore or make an existing part of the game more enjoyable.
What players may not notice-but still benefit from
A large share of development was less visible. That included bug fixes, refactoring, Creative Mode improvements, build and platform work, and general cleanup across the project. This work is easy to underestimate because it rarely makes for a dramatic screenshot. But it is what helps a game stay stable as new features are added. It reduces the chance that one improvement creates three new problems elsewhere, and it gives future updates a healthier foundation to build on. For a long-running game, that maintenance is not separate from development. It is development.
Building around the rest of life
Train Sim is not made by a large studio with a full team and uninterrupted workdays. I build it alongside a full-time job and family life, often in the ordinary gaps around everything else-an evening with my MacBook open while the TV is on and the house is still busy That means progress is rarely dramatic. More often, it is a feature completed in pieces, a bug narrowed down after several evenings, or a release assembled from many small changes that gradually became a meaningful update
Over a year, those small steps added up to nine releases and a much stronger version of the game.
Looking ahead
The most useful lesson from this year has been that an indie game does not need constant giant updates to keep improving. New trains and levels matter, but so do smoother systems, fewer bugs, clearer menus, and the unglamorous technical work that keeps everything moving. That is what this year of Train Sim development really looked like: new content, maintenance, experimentation, fixes, and a lot of small decisions adding up over time.
If you have played Train Sim, thank you for being part of that process. I’m looking forward to continuing to build on it.

I’ve been working on some major improvements to Train Sim’s Creative Mode to make building faster, safer, and more intuitive. Here’s what’s new.
A New Mode System
The editor now has three distinct modes, each designed to remove friction from the building process:
Build Mode Place new buildings and items without disturbing anything you’ve already placed. Existing objects are locked, so you won’t accidentally drag them while building. This was one of the most requested improvements from players.
Edit Mode Select and modify existing objects. Tap an object to move it, rotate it, or delete it. A contextual panel appears on selection, giving you quick access to all editing tools.
Terrain Mode Sculpt the terrain by raising or lowering the ground. The active tool is clearly highlighted, so you always know what effect you’re applying.
A label at the top of the screen shows the current mode, and the active mode button is highlighted for clarity.
Object Editing Improvements
Editing placed objects is now significantly more flexible:
Rotate objects Rotate any object clockwise or counter-clockwise. No more rebuilding something just because it’s facing the wrong direction.
Delete individual objects Remove exactly what you want. Previously, your only options were undoing the last action or clearing everything.
Reliable touch controls Objects now move only when you intentionally drag them. A quick tap selects instead of moving.
Improved Undo System
Undo has been completely rebuilt to be more reliable and scalable:
Undo object movement Moving an object can now be undone precisely. Implementing this revealed a subtle issue with Unity’s event ordering. Depending on timing, either the input event or the update loop could fire first, which sometimes caused undo to delete objects instead of restoring them.
Unlimited history The old system used a fixed array of 10 slots and manually shifted entries. It’s now backed by a dynamic list, allowing for unlimited undo history. This also fixed a bug where undoing the only placed object removed it visually but left behind invalid data in the save file.
Grid Snapping
Objects now snap to a grid by default when placing, making it easier to create clean, organized layouts.
Better Sharing
Shared Creative Mode levels now include terrain textures. If you build a desert, it will look like a desert when someone imports it.
This required adding new data to the share format while maintaining backwards compatibility. Older share codes still load correctly, just without texture information.
A Note on Mobile Touch
One of the more subtle bugs involved UI input “passing through” to the game. Tapping a button, like rotate, would also trigger a world interaction underneath it.
Unity’s standard fix works with a mouse but not reliably with touch input unless you pass the correct finger ID. On the frame where the finger lifts, that data can disappear entirely. This has been addressed and should work much better.
Try It Now
These improvements are available in the Train Sim Open Beta.
