The Gyeongbu high-speed line runs 408.5 km from Seoul to Busan in as little as two hours eight minutes, with dozens of trains a day — and Busan Station sits a ten-minute walk across a pedestrian bridge from the international cruise terminal.
Korea Train Express has run the corridor since April 2004; the full high-speed alignment followed in November 2010. Express services cover the 408.5 km in about 2 hours 8–15 minutes, all-stops trains take up to three hours, and the SRT from Suseo offers a second high-speed option on the same tracks. Standard seats start around ₩59,800 — first-class upgrades remain one of Asia's better-value splurges.
Busan Station is the southern terminus: a repeatedly rebuilt railhead in Dong-gu with direct access to Metro Line 1. Bujeon, a few minutes east, is the second hub for Donghae Line trains up the coast toward Ulsan and Pohang.
The rail-to-ship link is unusually short: the Busan Port International Passenger Terminal sits across the harbour road from the station, connected by a pedestrian bridge — ten to fifteen minutes with luggage, no taxi needed. Immigration on cruise days runs 20–40 minutes.
Metro Line 1 puts Nampo and Jagalchi market four stops south, Seomyeon eight stops east; Haeundae is about an hour away with one change. The Donghae Line's metro-style service covers the eastern beaches without touching the city centre.
Our read: the KTX is the way to arrive. Book the express, sit on the right side southbound for the Nakdong river flats, and walk to your ship if you are cruising. Skip the airport limousine from Incheon unless you are landing with a same-day sailing — the train from Seoul Station is faster, cheaper and drops you closer to everything.
