Suseo High-Speed Railway – SRT

From December 9, travelers in and around Gangnam no longer have to go to Seoul Station or Yongsan Station to catch high-speed trains to Busan or Mokpo. Instead of taking a KTX, travelers can now use the SRT service. The new high-speed rail service by SR has stations at Suseo (southeastern Seoul), Dongtan and in Jije (close to Pyongtaek).

Suseo SRT

For the first 50 km from Suseo to just before Jije the train travels completely underground. The 52.3 km rail tunnel is the third longest tunnel in the world.


Train Service

Suseo SRT

The SRT (Super Rapid Train) is operated by the SR corporation. Their fleet consists of Hyundai Rotem’s Sancheon trains, often called second generation of KTX, that can reach a top speed of 330 km/h. However, on the current tracks they are limited to 300km/h. The seats are more spacious than in KTX trains and each seat has power outlets for your smartphone or notebook.

The SRT closer in distance to Busan than the KTX meaning total travel time is shorter and prices are lower.
