Seoul to Daejeon
Seoul Station
Seoul and Seoul Station exteriors open the film, with KTX and other trains on the platforms, The Cinemaholic says.
MovieMaps lists Seoul Station among the film’s filming locations, crediting Filmap.
Most interior train scenes were shot in a South Korean studio, in a railcar built for the film, with the scenery outside simulated by LED plate rear screens, The Cinemaholic says.
Wikipedia says the LED plate set behind the train was modelled on the interior of the KTX-I, and that it kept the focus on the actors and was easier than green screen.
A working station with KTX and subway services; walk in from the forecourt. Anyone can enter the concourse.
