Temporary Military Railway

The Temporary Military Railway Office (Japanese: 臨時軍用鐵道監部, Rinji Gun'yō Tetsudō Kanbu; Korean: 임시 군용 철도 감부, Imsi Gunyong Cheoldo Ganbu), was a pseudo-corporate entity established by the Imperial Japanese Army to build and operate the Gyeongui Line railway from Gyeongseong (today: Seoul) to Sinuiju.

It opened the second railway line on the Korean Peninsula in April 1906, and was nationalised to create the National Railway in September of the same year.
