Technical Specifications

Interior

[edit]

The Korail Class 391000 train interior is the same as the Korail Class 371000, but there is a slight difference as it's a transitional type to the snout.

Driving equipment

[edit]

The Korail Class 391000 has a wider driver's window than the front of existing vehicles, slightly changed shape to improve vision, and is equipped with a CCTV monitor and an RF-CBTC speedometer, an automatic driving system from Siemens, to enable one-person operation.

The first generation was introduced on June 16, 2018 for the opening of the first phase section. At the beginning of its introduction, a gray and navy blue livery was used, but over time, it is currently running in green and light green livery.

[edit]

The second generation is being introduced in preparation for the opening of the second phase section on January 31, 2023. Unlike the first generation, the frontal appearance and livery were different, and single arm pantograph was adopted. It is produced in Dasys.
