How this page works

Every train between the two stations comes from the national public transport data service (TAGO) for the date shown: KTX, SRT and the slower Mugunghwa/ITX trains. From that list we work out the fastest and cheapest trains, the first and last departures, how many trains run and the usual gap between them. Fares are the adult standard-class fares the feed reports; Korail’s own booking site is the final word. The page is rebuilt twice a day (around 09:15 and 21:15 Korea time) and republished only when the numbers change.
