The 2nd locally produced Underground Electric Car Type 1 entered service in 2022. It was supposed to be completed around December 2020. This is the 5th locally produced metro set.
There is still one 4-car DK4 set operating on the metro operating on a fixed schedule.

Recently, most stations on the Chollima Line have been refurbished. Work started on refurbishment of Hyoksin Line stations by 2022, with works complete on Hyoksin Station by late 2022.
