Hmmsim Metro

Hmmsim Metro brings Line 1, the most complicated subway line in Seoul, to PC with the actual scenery, train driving sounds, and a realistic driving system reproduced in detail. The covered section runs from Kwangwoon Univ to Anyang/Gwangmyeong, roughly 43km and 30 stations forming the core of Line 1.

The route splits roughly evenly between ground-level and underground sections, so the experience varies as the train enters and exits tunnels. PSDs (platform screen doors), position indicators, and ATS signals are all implemented, and the cab is modeled close to the real thing. DSD (driver alert) keeps you honest by demanding consistent input as you drive.

The AC-DC switching section between direct-to-transfer voltages is reproduced for accurate operation. Multiple diagrams cover various trains and scenery changes as in-game time passes, with a 'hidden train' available once you have logged enough operation time.
