Luggage Allowance

Passengers may bring up to two pieces of luggage. Each item should not exceed 160 cm in total dimensions (sum of length, width, and height), with a weight limit of 30 kg to ensure safety and space for others.

Seoul to Osong Map

Plan your trip from Seoul to Osong via the Gyeongbu High-Speed Line. The track exits the Seoul metropolitan area, passing through Gwangmyeong and Cheonan-Asan stations before arriving at Osong. The transport system in South Korea ensures frequent departures from Seoul Station and Yongsan Station. This north-to-central travel route moves through the industrial and residential landscapes of Gyeonggi-do into the hills of Chungcheong-do.

Rail vs Bus vs Plane

Rail travel on the KTX provides faster city-center connections than buses, which are subject to highway traffic on the Gyeongbu Expressway. A bus trip takes significantly longer and involves potential road delays. There are no commercial flights between Seoul and Osong due to the short distance. The train remains the most logical and time-effective choice for this corridor.
