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 travel exclusively on dedicated Suseo–Pyeongtaek, Gyeongbu and Honam HSR lines. The Suseo-Pyeongtaek HSR line was built exclusively for this service.[3]
Branding
editBefore official announcement by SR, Ministry of Land, Infrastructure and Transport used tentative term called Suseo High-speed Railway (수서고속철도).[4]
On October 12, 2015, SR proposed three candidate name for new high-speed rail service – SRT (Super Rapid Train), HSR (High-speed train of SR), SRH (SR High-speed train) in which SRT (Super Rapid Train) was chosen.[5]
Electrification
editThe SRT operates 25 kilovolts AC on the entire line and interconnection with Korail is 1.5 kilovolts DC. At Suseo Station, the power is came from the rigid overhead lines before transitioning to overhead catenary 1500 millimeter wire after leaving Suseo Station at few meters. In Mokpo and Busan stations are feed at 25 kilovolts or 1.5 kilovolts each.

editKTX-Sancheon
editThe train service is operated using 22 KTX-Sancheon Class 120000 train sets and 10 KTX-Sancheon Class 130000 train sets. Class 120000 train sets was originally operated by Korail's KTX service before it was transferred to SR at the end of 2016, while Class 130000 train sets are new builds.[6]
Demand for extension
editSince 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.[7] In December 2016, the mayor of Pohang proposed running SRT service to Pohang station using the Donghae Line[8] In January 2021, the mayor of Changwon urged the SR Corporation to run SRT service to Changwon station using the Gyeongjeon Line.[9]
