What Makes Hmmsim – Train Simulator Stand Out
Hmmsim, the first Train Simulation game ever built in Korea, has been realized in mobile.
Hmmsim features basic route based on Seoulmetro Line 2, realized in the highest level of graphic.
Experience the metro operation.
Also, for the first time in mobile Train Simulation game, Hmmsim can add BVE Trainsim Add-Ons.
In Hmmsim, you can play BVE routes as the same
which you used to do in your PC.
This is the first mobile Train Simulator that
you can infinitely add Add-Ons depending on your preference.
See www.jeminie.net for details.
This Racing game offers engaging gameplay and regular updates for mobile players.

Community Insight:
This is a pretty good game. It is fun, but we wonder why we only have one line. Maybe in the second version. Anyways, great game.
This game is very good!!!!!!!!!! We like it very much.
We love this game a lot but we would love a Camera view.
This is the same like Openbve and its so awsome This game needs more updates . 5/5.
We played this game many times and we enjoyed It we like the announcement and has 2 languages Korean and English we enjoy this a lot.
Hello we are having trouble finding the underground part Im wondering if you need to have another map overall this is a great app the game and graphics are awesome and they are very clean but if someone can answer the finding the underground part that would be great.
We dont really use the actual Hmmsim. We use NYCT add-ons. We love the game though! GREAT GAME.
This is a great app. Very realistic.
Good graphics, easy controls, beautiful stations and tunnels Good job guys.
Really great game. Very good controls, excellent graphics and sound, the polish is amazing, we can tell the creator cared about making s high quality app. Love it.
Can you make another 1 free but with more trains and destinations like different cities please this will get u a lot of buzz if you do Philadelphia septa lines or MTA lines.
This game totally reminds us of the time when we were living in Korea. We just wish we could change the view. Also it'll be nice if we can download maps from the phone not through iTunes.
Pain in the butt to figure out at first but totally fun on the end.
Everything about this game is great.
This is a good game but we dont understand Korean we wish you could switch options and and turn the anousments (sorry we spelld it wrong)but other than that it is a good game.
We have 5 train simulator games including this one. If we vote right now we would give this game a three stars. But, if we voted before we got our other simulators we would give the game five stars. Its a good game to play if you are new at train simulators.
Can you add more stops and make Hmmsim 2 free because we want openbve and more stops we went on the website but its only for hmmsim 2 so make openbve trains and stops for free please.
Its a great game but we want to download BVE add-ons, we went to the website it said but the website is all in different language which we cannot understand so we cannot navigate through it.Can anyone guide us how do we download the add-ons.
We really enjoy this train sim game! Controls are simple and the graphics are great. A few areas to improve: says we're exceeding the speed limit when we're not, which is confusing. We'd also like to see signals in the underground sections of the line.
We love everything about this game except that you can't change the view. But overall great game:).
If u dont add it we won play it forever for real Thats true because we like seeing trains in games while Ur playing so bad plz add that.
The game is great but you only have one map the graphics are great and there is only one view. We hope you guys update it so there is more maps and more views.
We went on google and we searched it but we couldnt find it.
This is pretty laggy and not fun Is not what you think it is.
This game is a 2-star rated game in our opinion because there is only 1 route. We all want more routes.
We hate this game,do you want us to delete it.
The game can be played very well, but it has no other views rather than the cockpit, and stopping at the station has to be too precise.
We can not play for some reason and we came here to ask how do we play.
When we get to the app we click play like you would normally do but half the time the app crashes and the other half brings you to a screen to pick you route bu the play button which lets you start the game does nothing therefore that is all the game is unless you take a map from online or have to download it but that does not happen in mobile.
This game is stupid. All you do is sit in the middle of somewhere next to the tracks. There are no trains or sounds. You can't control anything. This game is basically a picture of train depots and tracks.
Do not download this app all you do is just sit in the middle of the train tracks there is no sound or movement.
Mor lines to be exact for next update those lines announced on the PA are interesting please add more lines we heard Line Number 7 lol.
Overall a great game, realistic sounds, realistic graphics, all kinds of good stuff! We know you're working on hmmsim 2 and we think there should be more camera views, moving trains, passengers, and more than one route that doesn't require us to download it from a computer. But great game, keep up the good work.
When we saw that your app uses BVE routes,we tried it out and it looks fantastic.Years ago we created the Blueridge route (USA) for BVE and we haven't watched our route for a couple years.The converter had no trouble at all and the result looks way better than we ever saw it on our PC,vivid colors,sharp lines. Our site for the route and train is "BVE in Virginia" if you have BVE but not our route.The converted zip for hmmsim is now available from our site so you can drive it without even needing BVE.
We really hope the developers can add some new lines for the next update! We cannot download them off the internet and convert them onto the game since we use a MacBook.
Thank you great team for offering such a great game for free and if it was not we would have bought it immediately! Just make an easier way to add the lines, thank you :).
This game is really fun and enjoyable. The only problem we have is leaving the app and returning. It would be great if you could return back to where you left off instead of starting the route all over again. Other then that, great game.
This reminds us of densha de go we used to play on the psp, and still waiting for the time that we'll be able to drive bullet train on the ios.
Please add option to "jump to station" . Beyond that, excellent work. (our use is NYCTA routes, via bve station.).
We think this is a great app but it is to hard to add on routes it should come with an update that comes with routes! On it.
What a realistic simulator!! Of course it would be great if the game adds more stations and subway lines other than Seoul Metro line 2, the current work is way over expectation.
There is only 1 level. Please add more.
When we start driving we hear the sounds of the train.
We really really really want to give 5 stars but there is only 1 level. You have to go online and drag them in. We think new levels should come with updates. It would also be cool if there were people or different things like that you could see.
One thing we wish it had was more routes and for a simpler way to download BVE add ons. Hope it gets worked on soon.
Great graphics. Great controls. Please add scoring options based on meeting a timetable to arrive at stations and proper positioning in stations. Also do file conversions for the extra lines and then charge for the easier downloads.
This is a great game, but it needs more lines to work with. Maybe something to think about in the next update.
We would love to see the NYC subway system included in the app. Overall good app but we just want the nyc subway system included with all announcements.
Beautiful game. Awesome graphics and very realistic sounds and movement. More lines thought instead of just one lines. A LOT OF PEOPLE are lazy, including us, so we think you should just add more lines into the game instead of having us downloading it ourselves. Great game tho.
