Hmmsim 2 is the sequel to the highly-regarded train simulation game, featuring significant upgrades in graphics and functionality. Players take control of trains on Seoul's iconic Line 2 and Line 7, navigating realistic urban environments. The game stands out by allowing users to import external routes through BVE Trainsim files, providing endless replayability. With a focused interface and authentic sound design, it delivers a professional-grade simulation experience on a mobile device.

Our Expert Score

85/100

Hmmsim 2 is a surprisingly robust train simulator for mobile. It captures the technical feel of the Seoul subway system with impressive detail. The graphics are a significant step up from the first game, offering much smoother framerates and cleaner textures.

What I love most is the ability to import external routes. While the base game is great, the community content keeps it alive. The controls are intuitive—balancing the master controller to hit your stop markers perfectly is rewarding and genuinely relaxing. If you’re a railfan looking for a mobile sim that doesn't feel like a toy, this is it.

The Best Train Sim Out There, But BVE Addons And Conversions Make Some Bugs
Sun May 27 2018 Close, crash.

I cannot stress how awesome the graphics are on the default lines 2 and 7, and even most of the BVE add on route graphic look so much better than even the actual BVE on PC! But, there are a few slight problems when it comes to converting to Hmmsim 2 format. Firstly, a lot of transparency seems to go away even with the use of SetDecalTransparentColor. This causes the converted trains (especially on New York lines) to have unnecessary opaque textures, making the train look odd. Next, sometimes the ground sticks into the tracks on some lines, I don’t know the cause. Finally, signals on converted routes don’t seem to load properly, as I usually get an oversized rectangle, also possibly due to the transparency issue. Aside from all of these minor issues, this is the absolute best train sim to use BVE addons, even the best mobile train sim ever, period! Edit: I forgot to say how simple it is to convert from BVE to Hmmsim! It is so easy, even with iOS! Just download the converter on your website, and transfer the converted .zip file on to your phone!

Amazing!😀

This is a great train simulator game, and it is so fun. I have a few suggestions, though. First, can you add a cab view? I would like it more if you did that. Second, can you add the ability to do a round trip? Third, can you add AI trains on both directions, so that there is train traffic? Fourth, I feel like it should be easier to convert bve routes and trains. Finally, maybe you can add a couple more metro lines to choose from, maybe other countries’ train lines. These are just suggestions to make the game better, but the game is still fun anyway.

I cannot add hmmsim routes on IOS

I like the game and all but there’s a slight problem, I cannot add hmmsim mta routes to iPhone even after I try downloading es file explorer and getting routes from hmmsim weebly, and when I close the app and restart the app, the routes don’t appear when the app reopens. Can you please fix this issue?

Love it

I play BVE train games on my computer from time to one and always wanted to be able to put it on my iphone or iPad. Now I got the chance to add my train simulation games to my phone and I love it. Hope a multiplayer option comes out. Good job hmmsim team. Please add backbone game controller support. Thanks

I love the game a lot but I would like to see added is to maybe make it more Easter to add routes because it is very hard for me to add routes like maybe have a shop where you get conies to buy routes or make something because it is hard

Ok

I like this game. It is very realistic and fun. The only thing that bothers me is that there are not enough train lines. Instead of Seoul subway I think it should be expanded to long distance train lines from other countries like the EuroStar and etc. This should be included for free or as an in-App purchase. This would be a very great addition.

Add more Trains and people to the trains.

I suggest that you should add more trains so that we can experience other trains. I would also want people boarding the train when arriving at a station and some people inside the train. And also departing the train, we should people in there.
