High-speed (6)
- KTX
Korea’s TGV-derived flagship halved the Seoul–Busan run: today the corridor is one of the most intensively served on Earth.
Wikipedia ↗ - KTX-Eum Jungang Line
The rebuilt Jungang line, run through since December 2024: EMU-260 sets from Seoul past Confucian Andong and Gyeongju’s royal tombs, down the Donghae line to Bujeon in Busan in 3 h 56.
Wikipedia ↗ - KTX Honam
Korea’s second high-speed spine: across the Honam rice plain to Gwangju and Mokpo’s seafood quays, where ferries fan out to a thousand islands.
Wikipedia ↗ - KTX Jeolla Line
Off the Honam high-speed line at Iksan and down the Jeolla branch: hanok-roofed Jeonju, Suncheon’s gardens and the Expo harbour at Yeosu.
Wikipedia ↗ - KTX Gangneung Line
Built for the PyeongChang 2018 Games: under the Taebaek passes in a 22 km tunnel, out to Gangneung’s espresso beaches on the East Sea.
Wikipedia (KO) ↗ - KTX-Eum Jungbu Inland
Korea’s newest inter-city railway, finished through to Mungyeong in November 2024: EMU-260 sets past Chungju and the Suanbo hot springs to the old post road town under Mungyeong Saejae.

Classic (4)
- ITX-Saemaeul
Tilting-comfort intercity that succeeded the storied Saemaul-ho, still running the full 442 km Gyeongbu spine from Seoul to Busan.
Wikipedia ↗ - Mugunghwa-ho
Korea’s beloved everyman Rose of Sharon train: cheap reserved seats and rattling coaches taking the slow road from Seoul to Busan.
Wikipedia ↗ - ITX-Maum · Donghae Line
Korea’s newest line: the last east-coast gap closed on New Year’s Day 2025, and now one train runs the whole East Sea shore, Busan to Gangneung.
Wikipedia ↗ - ITX-Cheongchun
Double-deck 180 km/h EMU on the Youth Line, racing up the Bukhan River to the lake city of Chuncheon, home of dak-galbi.

Scenic (5)
- S-train (Namdo Ocean)
Since September 2025 the S-train sweeps the whole south coast from Busan to Mokpo, crossing the brand-new Boseong–Imseongri line past tea fields and tidal bays.
Wikipedia ↗ - G-train (West Gold)
The West Gold train ambles down the Janghang line’s tidal-flat coast, foot baths steaming on board, with Daecheon beach and the Geum estuary out the window.
Wikipedia ↗ - A-train (Jeongseon Arirang)
The Arirang-themed A-train leaves the Jungang main line at Jecheon and threads the Jeongseon canyon to Auraji, where two mountain torrents meet.
Wikipedia ↗ - DMZ Peace Train
Tourist train relaunched in 2026, running to Dorasan: the last station on the line before North Korea, at the fenced edge of the DMZ.
Wikipedia ↗ - Baekdudaegan Canyon Train
White-and-crimson canyon cars crawl the upper Nakdong gorge at 30 km/h: stove-warmed in winter, windows flung open over rapids no road reaches.

How many train routes does Korail run?
15 of the routes in this atlas are Korail services, covering 4,168 km across 1 country (South Korea). That is what this atlas draws, not the operator's whole network — a national railway runs thousands of local services no map of notable journeys would list.
What is the fastest Korail train?
The KTX, Seoul to Busan, at up to 305 km/h. Its fastest scheduled run takes 2 h 15 min over 417 km.
Does Korail run night trains?
Not in this atlas. All 15 Korail routes listed here are daytime services.
When was Korail founded?
Wikidata records the company's inception as 1963, and files it as a railway company. The oldest railway it runs over in this atlas opened in 1984 — the line and the company are rarely the same age, and this page dates both.
