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.

so cool sugooi
I've owned the game since its initial release in October and have played around 550 hours in that version. I have to say this is one of the most enjoyable transport management games I have ever played(I have played Transport Fever 1/2, Cities Skylines 1/2, Soviet Worker and a few others to name a few). To put it into perspective, I have rebuilt the NYC Subway 3 times, Boston T, DC Metro, MSP Metro, made my own version of the NYC Subway and rebuilt the Twin Cities Rapid Transit tram lines, among other things. Does it have bugs? Alot. Do the devs fix them? Everytime, and are constantly updating everyone on the discord page. The game has developed alot since its release and I cannot wait to continue playing as more stuff is added and more cities are put in. The modding community(Railyard) is also fantastic and deserves its own appreciation as well. Highly recommended for anyone geeky enough to want to play this kind of game and willing to put in around 15-30 minutes to get over the learning curve. 10/10

The game's latest update 1.5.0 has brought some major improvements: 1. trains won't travel back in time anymore. (my own observation) 2. pathfinding is significantly better, now people more often find the closer station for their travel (just observed one instance of travel path in Miami still choose walking to a further station) 3. the game is now less difficult thanks to a few balancing modifications: -people are now willing to walk a bit further. -light rail/station building price is now lower. -populations accepts more transfers now. -difficulty labels were added for each map. -travel pattern is now realistic to its every own city. 4. medium and hard maps are now profitable through good design and thus playable. I have to say the lowered difficulty has definitely boosted the experience a lot. Well done to colin and the rest of the dev team for the well worked update. However, there's still plenty room for improvements for the overall game experience. And I hope that, in the future, updates of this quality can bring this game to a new height. Some ideas: 1. The game still needs better and more information/statistics. 2. a champaign working as an advanced tutorial could be nice for new players. 3. Maybe there could be a relay mode where players can collaborate. By the way, I have to mention my game crashed the second when the 1.5.0 release came out, and my high scoring Liverpool daily challenge was gone :( Below is my old review: Not recommended at this point. Pros: 1. released on time. 2. has achievements though without pictures. 3. offers real travel data for planning. 3. load-save was broken on release but now fixed. Cons: The game has quite some bugs: 1.Pathfinding system is broken so you will have trains that travels to the past. 2.Populations can't find stations at their door but can easily locate a station 25 minutes of walk away and say ok I'll drive instead. The game offers little experience: 1. Travel patterns does not evolve around your lines but stays what currently in real life is. So it is only profitable to build in cities that have extensive subway networks in real life, and you could hardly make a profit in cities which does not have a subway network, since all demand is scattered and no demand ever shows up for your new lines. That alone excludes 70% of the maps from being profitable and playable. And many of the 30% generate profits so little that you need to wait hours in game to earn liquidity just enough for building another one or two stations. 2. The game does not allow you to build signals. Single tracks could only go one way. You cannot route a commuter line on a single track cause it can't find a way back. 3. The game does not allow pre-assigning a route before construction. Only after you build everything down, can you find out if something's wrong. You start a daily challenge (does not allow save-load), happen to spend most of your 3b starting funds for a well planned subway system, and you find out a part of the one-way track was built in reverse and your subway route could not find a path. There is nothing you can do but to abandon the challenge since the cost for rebuilding that part exceeds your liquidity, and you are not allowed to take a loan at this point since you have not generated 100m of revenue. But you can't since you could not assign your route. 4. The game has no bulldozer. With a simple right mis-click you can accidentally delete vital stations and tracks just constructed before you successfully establish your routes. Yes, load-save has been fixed, but why do I need to load-save if the game does not allow you to easily do something silly. The game needs to at least have a confirm button for destruction. 5. The game only allow you to charge a one-time and set-amount of fare. What I understand is that longer distance does not mean more revenue per passenger. 6. I had to manually choose my better graphics card in my PC settings. In game settings could not work properly and game ran slow and lag with internal graphics card.
As someone who owned the game before the Steam release, and someone who has been at the forefront of the modding scene for most of the game's life, I am a little biased. However, I do think that the game has made significant progress towards community concerns since the Steam launch. There genuinely is a good game here, albeit one that could benefit from more performance improvements and a review of open bugs before moving onto new features. But overall, the game has improved significantly since both the initial launch and launch on Steam and I feel confident in recommending it to people.
I've been waiting for this game to come out on steam for a very long time and while I like the game there are a lot of things wrong with this game. My biggest issue is how reliant it is on profit to expand when most real world metro systems operate at a deficit. They should make it so that you can ask for grants or money from the city if your doing good. Another issue I have is how the commuter rail works. I can perfectly copy real world commuter lines and it would still have very low ridership, they should make it so that the range of commuters that ride on commuter stops are higher because I wasted like 30 minutes one time just for commuter rail to not be profitable. Nonetheless, I will recommend this game because it is a good game, and these issues will probably be fixed in the future. I wish that they added more European cities like in Germany or Spain because like 80% of this game's cities are American. Also one more thing, I think that this game is pretty overpriced, $40 is insane and I'm lucky that I managed to get it during a sale.
A bit slow paced, but good fun for those that like city builders and similar.
Es un juego bastante sencillo con el que poder dibujar líneas de metro, pero la gracia es que son en ciudades con datos de residentes y trabajadores reales, así que es muy interesante poder simular los flujos de movilidad de una forma realista. Lo llevaba siguiendo desde incluso antes de que el desarrollador lo vendía en su web, que ya me interesó en su momento pero estaba pendiente de que lo sacase por Steam por comodidad. Aunque justo cuando se estrenó había cosas importantes por pulir, me sorprendió para bien y han sacado actualizaciones que mejoraron significativamente el juego, han añadido más mapas y confío en que irán trayendo más novedades. Si te interesan este tipo de juego lo recomiendo, te puedes entretener bastante.
Amazing game, would recommend, has all features that I would want
extremely simple game with little to no bugs. very addicting. only complaint is that it's not easy to learn on your own and outside community help is often needed. 10/10 would recommend!
Love it
