The **Ungna Line** (Korean: 웅라선) was a railway line of the [South Manchuria Railway](/source/South_Manchuria_Railway) (*Mantetsu*), connecting [Unggi](/source/Sonbong_Station) with the important port city of [Rason](/source/Rason).

## History

Seeking to create a shorter route from Japan to [Xinjing](/source/Changchun) and [Harbin](/source/Harbin) in [Manchukuo](/source/Manchukuo), the South Manchuria Railway took over control of the [Chosen Government Railway](/source/Chosen_Government_Railway)'s [Sangsambong](/source/Sambong_Station)–Unggi **Domun Line** in October 1933,[1] [2] creating the [North Chosen Line](/source/North_Chosen_Line). Although Unggi was a satisfactory port, a larger one was built at Najin, so Mantetsu built a new line to connect the North Chosen Line to the new port facilities. This line, the 15.2 km (9.4 mi) **Ungna Line** (**Yūra Line** in Japanese), was opened on 1 November 1935.[2] At the same time, the [Najinbudu Line](/source/Rajinhang_Line) was opened to connect the main railyard at Najin to the wharves at the port.

Following the end of the [Pacific War](/source/Pacific_War) and the [partition of Korea](/source/Partition_of_Korea), the Ungna Line was taken over by the [Korean State Railway](/source/Korean_State_Railway), which eventually merged it with several other lines to create the current [Hambuk Line](/source/Hambuk_Line) between Najin and [Cheongjin](/source/Chongjin_Chongnyon_Station).[3]
