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 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.
To start your journey, push the master controller forward to accelerate. Watch your speed indicators closely as you approach stations; the key is to gradually reduce power and apply brakes so that you stop exactly at the designated platform markers.
The core gameplay involves navigating the circular Line 2 and the north-south Line 7. You must manage door operations, adhere to speed limits, and maintain a strict schedule to ensure a high rating at the end of each run.
Yes, Hmmsim 2 supports the addition of external routes created for BVE Trainsim via file importation.
