This article includes sentences which may cause misunderstanding.
It's true that Yeongdeok - Pohang Line newly opened. But, the sentence below is not correct.
"the 36.7 km Taehwagang – Ilgwang section of the Donghae Line is scheduled to open in late 2019, connecting with the 28.5 km Busan – Ilgwang route which opened in December 2016."
Strictly speaking, the Taehwagang - Busan section has already been built more than 70 years ago. But, this section is under double-tracking and electrification to be an urban rail of Busan. So, as the urban rail, the sentence above is true.
