SR Corporation (, formerly Suseo High Speed Rail Corporation),[2][3] also known as Supreme Railways,[4] is a South Korean rail operator that operates high-speed rail services.
The company was established in December 2013 and adopted its current name in June 2014. In December 2016, SR Corporation officially launched its SRT (Super Rapid Train) services on an open-access basis. By January 2021, the company's services called at 17 stations, three of which it managed directly.[5] The merger of SR Corporation and the national passenger operator Korail has been repeatedly mooted and fallen through; presently the company remains an independent competitor to the incumbent's KTX services. Recent initiatives have included the greater use of local component production and the in-housing of rolling stock maintenance.
