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 SRT runs the Seoul–Busan route 8 minutes faster than KTX as it travels exclusively on dedicated Suseo–Pyeongtaek, Gyeongbu and Honam HSR lines.

[4] Before official announcement by SR, Ministry of Land, Infrastructure and Transport used tentative term called Suseo High-speed Railway (수서고속철도).

[7] Since Super Rapid Train only has two routes, there are many local cities that only KTX serves.

In November 2016, Jeonju and Yeosu urged the SR Corporation to run trains on the Jeolla Line.
