About

Subway Builder is a hyperrealistic transit simulation game built using live data from US, UK, Irish, French, and Japanese cities.
Real-World Passenger Simulation
Millions of commuters are generated from Census and Redistricter data and simulated using the same pathfinding algorithms you use on your phone. Your job is to design a route network that gets the most people to their destination as fast as possible. Juggle station placement, transfer dynamics, and train frequency to maximize ridership.
In-Depth Analysis
Explore how individual commuters weigh tradeoffs between wait times, transfers, income distribution, delays, and more, to pick their commute. Understand which routes, stations, and trains your commuters take and use that information to optimize your network.
You must also find the right balance between cost and time using this analysis. Too many trains on a line or an overcrowded station may cause delays or disruptions.
Authentic Data
The US, UK, Ireland, France, and Japanese census records home and workplace locations. The game generates millions of commuters with homes from that and then uses a distance-based gravity model to assign them all workplaces. They're also assigned times to leave to/from work in a distribution similar to real life. Please note that a broadband connection is required to maintain the real data used by the game.
This decision is then made based on how long each commute method takes, how much it costs, and the value of their time (different commuters can have different incomes).
If they decide to take the subway you can follow their commute (and thousands of others simultaneously) as they get to work. If a train is delayed or cancelled, it will affect their commute and future commuters will take that into account.
College and airport commuters are also simulated and they behave differently since they have different income distributions and commuting times. Federal data is used for college student counts and FAA data for airports.
Current cities in Subway Builder include: Atlanta, Austin, Baltimore, Boston, Charlotte, Chicago, Cincinnati, Cleveland, Columbus, Dallas, Denver, Detroit, Honolulu, Houston, Indianapolis, Miami, Milwaukee, Minneapolis, New York, Philadelphia, Phoenix, Pittsburgh, Portland, Salt Lake City, San Diego, San Francisco, Seattle, St Louis, and Washington in the US. Birmingham, Liverpool, London, Manchester, and Newcastle in the UK. Paris, Marseille, Lyon, in France. Tokyo, Osaka, Nagoya, Sapporo, Sendai, Hiroshima, and Nagoya in Japan, and Dublin in Ireland.

I'm very biased as a modder of the game, but there's a lot of potential here. Hopefully with further updates it will reach that potential.
Game is not ready for release. The idea is fun and the first five minutes are great, but eventually you start to notice loads of bugs and things that need improvement. The game looks pretty but it's all just bells and whistles. When it comes to the content it's severely lacking and incomplete. Here are some of things that put me off: - No offline support which is weird for a singleplayer game - The blueprint system is unique but incomplete. I have to clear all of my future plans if I want to make one little upgrade somewhere. To make it better, allow the player to organize their plans - Simulation speed is laughably slow, especially if the simulation is being offloaded from my PC to some server. Nobody needs to simulate a game second-by-second - Map pool is very odd. Missing big cities with famous subway systems but has small American cities - No zones yet, which is a pretty important part for a subway system - Stations and tracks are not upgradable, meaning I need to build a whole new station from scratch if I want to change one thing. - The routing system is awful. I need to either go add every station individually every time I make a change or rely on the buggy auto-routing. Looking forward to playing when they re-release the game, since at this rate no one will want to play this.

I'm just so sick of unfinished games.... I miss paying for a game that was actually COMPLETE
Awful tutorial that doesn't even cover the basics of the game, FPS drops like my PC is about to explode, always online, the most unsympathetic developer (Colin) I've ever encountered, and a lot of bugs. People say it's playable and enjoyable when you mod the game, but if you *have* to mod a game in order for it to be playable and enjoyable the game shouldn't be released yet.
The dev behind this game knows ♥♥♥♥♥♥♥♥♥ about how gaming and modern games are structured. A non-Steam launch for an early access game is not unheard of but really weird these days, nobody wants to sign up to your ♥♥♥♥ website to download a game. $40 on Steam for an indie game developed mostly by one person is just nuts. That is AA territory, you can get Cities Skylines 2 for that money. Putting the website version under a serial key DRM that you need to unbind every time you switch systems like it’s early-mid 2000’s. I don’t think I need to explain how out of touch this is for 2026. Always online for a game that has no excuse. No sane gamer in 2026 tolerate ♥♥♥♥ like this. At first I thought he’d learn from the community but since the beginning he’s been consistently ignoring anyone who knows anything about gaming. I thought Steam launch would humble him a little bit but nothing ♥♥♥♥♥♥♥ gets through his thick ego. Why did I still buy it at Steam launch? Because there is no alternative I returned it. Game is now unplayable, last time I checked it was fine but he also ♥♥♥♥♥♥ it up somehow. If you’re reading this and want to buy this game, do NOT buy the game. I regret ever playing it.
Not a bad game, absolutely not worth $40 though.
I honestly don't get the hate the developer is getting. This is an amazing game, fairly priced by today's standards and with enough features to be called complete already. Yes, an offline mode would be nice, but for me it's honestly not a dealbraker.
Yeah gonna go ahead and refund this one. Basically no tutorial, moving the camera around feels laggy even before you've built a single bit of rail, and it's just clearly lacking a ton of polish. And that's all to say nothing about the fact that a they made a single-player sandbox game online-only. "Oh it's so the game isn't too big and it can run faster" yeah right dude
I don't know where to begin with this one really. The controls feel super rough, I try rotating the map slightly, and bloody hell North is at the bottom right of my screen now. Every menu feels like it needs an instruction manual to navigate. (Tutorial barely covers anything) Hilariously, pressing Shift+Tab to check how many minutes I had on my current session would not work. How on earth do you miss something like that, it should surely be simple play testing. I really can't recommend this game if it's in THIS sort of a state, although with the vibe coding allegations I hear, can't really be surprised. I'm going to try and refund this. Honestly, provided both games are at full price, save yourself £9 and just buy NIMBY Rails instead. Much better game, with more effort put into it by the dev, also has much more content wise, an active mod scene, and a really helpful community. Oh, and it doesn't try and sell itself as a full release.
For my laptop the game was too much. I was getting frames under 15 all the time, it wasn't playable. Wich is strange beacuse my laptop can run games that are 3D and have good graphics and I mean it, I haven't had trouble with my laptop so far even tho it's quite old, but then comes this 2D game that my laptop actually can't run. I made a metro line and the performance got even worse. If you have a pc/laptop that's similar to mine you shouldn't buy the game beacuse your laptop/pc probably wouldn't be able to run it.
