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.

Reviews
Negative - handling of critizism and communication (as others quoted) - performance issues (in my case it doesnt always run smoothly which is not to bad) - parts of it are vibe coded (that's really my biggest concern, although there are "real" develeopers in the team - contrary to what some people here suggest) Neutral: - lack of content: The game is still in active develeopment and has a mod manager so I'm cautious optimistic about that - need to be always online: I personally didnt have problems with that but I see why it's a problem Positive: - in its current stage it does make fun - it has some cool features nimby rails for example doesnt have - it is intuitive and doesnt need dozens of tutorials, building is also relatively fast - it has dozens of cities (Railyard) and an active Community, in the past the develeopment team listened to feedback and implemented requested features. Of course thats my personal opinion, so take it with a grain of salt. I do think this game has potential to be a really cool and fun game for its target group with enough content for everyone. So as long as it is actively develeoped I'm staying positive.

Seriously I dont care about this always online thing or that there are still bugs in the game. Those things for me are Understandeable even thought I get why some people are not happy about them, but creating a game like this and not taking height difference of the land into account is what completely breaks any immersion i could have had in the game. San Francisco flat as a pancake? Are you kidding me? Seriously thinking about refunding the game.
Don’t buy the game in its current state; it’s still far from complete, full of bugs and missing features. Only buy it if it’s 50 per cent off or more; it should cost no more than €15.
Good concept, however the game is not optimized well at all and stutters like crazy at all times. I've also encountered a really annoying bug where I can't select text boxes, whether its when I'm trying to name a line or even type a name for my save game. I'm hoping for fixes down the line, but I cannot recommend the game in its current state, for $40 nonetheless.
这期神了😂 如果你想试试半成品的感觉你就来玩 地图缩小是会出bug的,最神的是,这个报纸系统刷了一次就不刷了,居然在论坛里看到是已经写好的文章直接套进去的,连用生成器都不愿意吗?那还开发这个新闻功能干啥?还卖这么贵,评价为不如去抢银行。后续更新再不改,我只能说不如退款
It's a really good game. I'm hooked. However, I do agree with the sentiment that this game is incomplete. This game is nowhere near completion, its got its fair share of bugs, but it is fun and very fun. It's a very satisfying game. I REALLY ENJOY IT however it does have its fair share of problems. Its also got a pretty nice modding scene. You shouldn't jump onto this game with the expectations that it is a finished product. It's an EARLY ACCESS game and they do have a clear roadmap. I bought this game because I'm interested in it and I've been waiting for a long time for it to release on steam. Waiting for it to get better. However, I will have to note the only reason I bought it was because of regional pricing. This game is not worth it at the full price of $30-40 which is really expensive for an "indie game". It's justifiable at a discounted price. I bought this game for around $10, its very much worth it at this price. I haven't found any game breaking bugs yet, placing down tracks works fine, not the best but it works just needs a bit of fiddling around it. I personally don't get why it needs to be online only but for me, but most of the time I'm gaming I'm connected to the internet and the game works just fine no issues whatsoever. I'm assuming the online only is for license checks. My main issue however is just the performance, like you cannot tell me with my pc (while not the best) that could easily run cyberpunk 2077 at 80-100 fps is struggling to run a glorified version of google maps. It could be my CPU but the usage seems to be moderate, so I'm assuming its about the optimization of the game itself. My GPU however shouldn't have a problem running, again, a glorified version of google maps. Doesn't matter if its 2d or 3d the game seems to really struggle with the simulations. It heavily swings around 10-60fps. In addition, the more you build the laggier it gets by that I mean significantly laggier. tl;dr It's a good and fun game but not worth it at $30-40, wait for a sale. This game is unfinished and still needs a lot of work. Theres issues with performance but it is playable. I'd say wait for the game to be more polished first or wait for a sale. It's worth trying out though I'd say just not at its full price point.
Fun game and a great way to unwind and just build subways like crazy. If you enjoyed Cities Skylines but don't want to go through the effort of building an entire city just to build subways, this game will be fun for you.
I have debated on whether I wanted to do a review or not. I have elected to, for several reasons. The first is what I believe to be unfair criticism of the game. The hard requirement to have an internet connection isn't preferred for me..but one that simply doesn't have any bearing. I always have my computer on and running, and connected to the internet. Having cloud saves is part of this. If this is a show stopper, fine..but I just can't see this being a problem for any more than a small minority of players. OK. Let me preface this review with the notion that I have been playing railroad and transportation games for a very, VERY long time. Like the original Sid Meier's Railroads, and all versions. Chris Sawyer's Locomotion. In fact, just about every transit game you can point to. Is this game the best one? No...NIMBY is my personal favorite, due to the complexity, and the vast gameworld. For Subway Builder, this game comes with about 36 cities. Several hundred more are available for download. I don't forsee needing to download any additional cities, as each one is quite a project. My training map, Nashville, took about ten hours, and I wasn't 10% done. My second map, Portland Oregon, is where I was born. Pretty fun to see areas I was familiar with. I may put a stop outside my old house! OK. The gameplay. That's why you came to read this review. Heavy and light metro, trams, and commuter rail. The ones you choose to use is a function of your cities' density. Each city is completely different. Sprawling, spread out cities may not have a dense urban core, so light rails might be preferred. A location like New York City might have a MASSIVE, heavy rail network, running a large number of cars, at a very short frequency. In real life, London has one rail line where they pull in and out every single minute. It is possible to do that with this game as well. The physical mechanics of this game are relatively straight forward. The tough part is at the start of the game, and developing a game plan. Some use actual data to see where to set up the lines, I see that as kinda defeating the spirit of the game. YOU need to see where YOU want to place stations and lines. Clearly, the BIG circles of both population and workers need to be carefully considered. Airports and universities, and the areas where the people commute from are a nice start. The mechanic of having different levels of stations and tracks is terrific. You can have a station at street level, and additional stations below it. If they're close enough, the overlapping stations can allow for direct transfers between lines. A heavy metro line can have light metro lines spreading out like a fish bone pattern. The three billion dollars you start with are critical. You need to CAREFULLY spend this initial budget, in order to fund additional lines. Nashville, my first city, I messed up and blasted through some buildings, and this ate up my money pretty hard, It took one FULL hour to save up enough monies to expand my lines. There is a tremendous amount of data for an old retired scientist like me. I love me a good spreadsheet! Specific information on ridership at each station, and detailed rider and financial data, broken down into hourly increments. You're also provided warnings if a train is over-crowded, and if a line needs more cars, or a higher frequency of visits. Given that one large city will take probably 20-30 hours to complete, I believe that I will get way more gameplay than the $30 the game costs. There is good value here, and better value if they made loading the modifications into the game a little easier. That's a mild complaint for me, and it gets a little fiddly. Stability is not a concern, and neither is lag. There have been some reports that this can be an issue, but also, more recent reports have suggested that the developers have taken some recent actions to enhance the optimization. I have a good system, and zero issues with CPU/GPU running excessively, or hot. I like this game. It is very satisfying to develop a chunk of line that immediately becomes productive. The game isn't terribly difficult, so long as you put stations and track down reasonably efficiently.
I have been into urbanism and city planning for a year now and I must say that this game impressed me. Unlike other subway builders, this one is unique in its realism. The sheer fact that the population data is from actual records is quite literally impressive. I would say that this isn't really a game but rather a simulation of being an actual public transit planner. I would recommend this game to anyone fascinated in subway systems, city planning, public transit and overall anything related to public transit and cities. Also cheers to the message in the discord server, yall guys are cool!
This game is an autistic subway lovers dream, the level of detail, the information available to you, there so much to dig into and its all wrapped in this neat little pleasant looking and sounding package. The amount of choices you can make, where the rail lines should go, at what elevation to put them based on the different costs, which trains go to which stations and how many trains to put on each line, compound that with the absolutely MASSIVE maps and the fact they use real world census data for each map and there is much do learn and do. The games visuals and sounds are also just extremely pleasant, nothing overbearing or too complex. They really just add to the very analytical atmosphere and are extremely good at telling you what you need to know.
