Subway Platform Screen Doors
Platform screen doors show how strongly subway safety has become part of public infrastructure in Korea. The barrier between the platform and the tracks helps prevent falls and accidental contact with trains while also reducing wind, dust, and noise. Korean subways carry large crowds, especially during rush hour, so even a small incident can quickly create serious danger and widespread delays. After a series of accidents raised public concern, transit agencies and local governments installed screen doors across the system. Today, they are so common that a station without them can feel unusual. The system also requires precision: train doors must stop in exactly the right place, and the platform equipment, maintenance, and operating systems all have to work together. A malfunction can delay service, which makes regular inspections and trained maintenance staff essential. To passengers, the doors may look like a simple glass wall. Behind them is a safety system working every time a train arrives.
