The Songdowŏn Line is an electrified secondary railway line of the Korean State Railway in Wŏnsan Municipal City, North Korea, running from Segil on the Kangwŏn Line to Songdowŏn.
It is not known when the line from Wŏnsan (actually, the line branches off from Segil) to Songdowŏn was opened, but the Songdowŏn−Segil section was opened on 23 September 2014, with a special ceremonial train marking the opening; this inaugural train was pulled by a Sŏngun Red Flag-class locomotive.
Songdowŏn is the site of the Songdowon International Children's Camp, and there is a resort.
