TheSuper Rapid Train (Korean: 수서고속철도),^[2] often known asSRT,^[2] is ahigh-speed rail service in South Korea operated bySR Corporation. The service starts atSuseo station in southeast Seoul and terminates at eitherBusan station orMokpo 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 thanKTX as it travels exclusively on dedicatedSuseo–Pyeongtaek,Gyeongbu andHonam HSR lines.^[3] The Suseo-Pyeongtaek HSR line was built exclusively for this service.^[4]

Before the official announcement by SR,Ministry of Land, Infrastructure and Transport used the tentative termSuseo High-speed Railway (수서고속철도).^[5]

On October 12, 2015, SR proposed three candidate names for the new high-speed rail service – SRT (Super Rapid Train), HSR (High-speed train of SR), and SRH (SR High-speed train). SRT (Super Rapid Train) was chosen.^[6]

The SRT operates 25kVAC on the entire line and interconnection withKorail is 1.5 kVDC. At Suseo Station, the power comes from rigid overhead lines before transitioning to a 1500mm overhead catenary wire after leaving the station.

Legend

The 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.^[7]

Since Super Rapid Train only has two routes, there are many local cities that only KTX serves. In November 2016,Jeonju andYeosu urged the SR Corporation to run trains on theJeolla Line.^[8] In December 2016, the mayor ofPohang proposed running SRT service toPohang station using theDonghae Line.^[9] In January 2021, the mayor ofChangwon urged the SR Corporation to run SRT service toChangwon station using theGyeongjeon Line.^[10]

On September 1, 2023, SRT services using Jeolla Line, Donghae Line and Gyeongjeon Line were launched.^[11]
