Hmmsim Metro

Take the role of a subway driver on a recreated section of Seoul Subway Line 1, spanning about 43 km and 30 stations between Kwangwoon University and Anyang or Gwangmyeong. The route includes both above-ground and underground sections.

Operate the train by controlling its cab systems, adjusting speed to ATS signals, and making accurate station stops. Driver-alert monitoring and AC/DC power changes at neutral sections add further tasks during a run.

Choose from different trains and service diagrams, with scenery changing as time passes and options for different conditions. AI trains and passengers bring activity to the line and its platforms.

Players often praise the detailed recreation of Seoul and its Line 1 scenery, along with the realistic train controls and the sense of operating a working subway. Many enjoy learning the demanding driving systems and meeting the challenge of precise stops. Some also call out AI trains and passengers as additions that make the route feel busier. The learning curve is a recurring drawback, though; some players find the controls and tutorial difficult to get started with.
