The Super Rapid Train,^[2] often known as SRT (Korean: 에스알티; RR: eseualti),^[2] is a high-speed rail service in South Korea operated by SR Corporation. The service starts at Suseo station in southeast Seoul and terminates at either Busan station or Mokpo station.

Around 86% of the train service runs 50 meters underground between Suseo and Cheonan-Asan stations. Dongtan station, the first station after departing from Suseo, is the first underground high-speed railway station in Korea. The SRT runs the Seoul–Busan route 8 minutes faster than KTX as it travels exclusively on dedicated Suseo–Pyeongtaek, Gyeongbu and Honam HSR lines.^[3] The Suseo-Pyeongtaek HSR line was built exclusively for this service.^[4]
