Comparing Daejeon Station and Osong Station

For travel to central Daejeon, consider Daejeon Station first; for the Sejong and Cheongju areas, consider Osong Station first. Both stations are listed as stops on the Gyeongbu High-Speed Railway. You must check whether your selected train actually stops there.

Osong Station is in Osong-eup, Heungdeok-gu, Cheongju-si, Chungcheongbuk-do. Its road-name address is 123 Osonggarak-ro. The address is also listed under Osong Station in the Cheongju City Self-Service Civil Document Kiosk Location Guide.

How Do the Gyeongbu and Honam Lines Split at Osong Station?

Osong Station is the junction of the Gyeongbu High-Speed Line and the Honam High-Speed Line. In Korail's operating network, the Honam High-Speed Main Line connects Osong and Gwangju Songjeong. As of September 1, 2026, the route distance is 183.8km.

Phase 1 of the Honam High-Speed Railway opened on April 2, 2015. Its stations are Osong, Gongju, Iksan, Jeongeup, and Gwangju Songjeong. The Daejeon and Daegu city-center sections of the Gyeongbu High-Speed Railway opened on August 1, 2015.

The route distance is based on Korail's Passenger Train Operating Information. Opening dates and stations can be checked in the Korea National Railway's Major High-Speed Railway Projects. Do not assume that every train stops at a station just because it appears on the route map.

Checking Fares and Timetables from Seoul, Yongsan, and Suseo

To check the exact fare to Daejeon or Osong, enter your travel date and train. This article does not estimate unverified route fares. Check journey times and the number of daily services using search results for the same date.

Korail reduced KTX fares by an average of 10% from September 1, 2026. The reduction was based on existing SRT fare levels. Do not apply the average reduction rate uniformly to the previous fare for each route.

These amounts are examples from the announcement explaining base fares after the reduction. The actual amount paid varies by train, date, and discount. You cannot calculate fares for Daejeon or Osong routes from the amounts for these two routes.

1. Select an available departure station from Seoul, Yongsan, and Suseo.
2. Enter Daejeon or Osong as your arrival station.
3. Set your travel date, then check departure and arrival times for each train.
4. Check the seat class and the amount payable after discounts.

When reading older articles about fare increases, distinguish between their effective dates. On March 7, 2025, Korail stated that the increase rate and timing had not been finalized. This article uses the fare reductions effective September 1, 2026, which were announced later.

KTX Departures from Suseo and Discount Conditions After Integration

Search for and book high-speed trains departing from Suseo in Korail+ as well. From September 1, 2026, KTX and SRT operate as a unified KTX service. Former SRT trains have been renamed KTX-Sancheon.

New routes via Seodaejeon and Gupo stations have also been introduced for departures from Suseo. Select your travel date to check the number of services via Seodaejeon. Daejeon Station and Seodaejeon Station are separate stations, so check the station name again.

Even with broader discounts, not every seat receives the maximum discount. Check Korail+ for offers that apply to you. The source is Korail's High-Speed Rail Integrated Operations Announcement.

Example of a Conventional-Train Transfer Discount at Daejeon Station

If traveling from Suseo to Yeongdong, also search for a journey with a transfer at Daejeon Station. Korail presented this journey as an example of the transfer discount. The discount applies to the conventional-train fare from Daejeon to Yeongdong.

The following guidance appears in Korail's “Korail to Begin Integrated High-Speed Rail Operations in September.”

If you purchase tickets together for a KTX service departing from or arriving at Suseo Station and a conventional train, you can receive a 30% discount on the conventional-train fare.

The discount in this example is 30% of the conventional-train segment's fare. Do not calculate it as a discount on the total journey cost. Since the tickets must be purchased together, check that the transfer discount is shown before paying.

The Metro at Daejeon Station and Sejong BRT at Osong Station

At Daejeon Station, consider a connection to Metro Line 1. If traveling from Osong Station to Sejong, first decide which BRT stop to get off at. Do not judge your arrival time at your final destination solely by the train's arrival time.

Transferring to the Metro at Daejeon Station

After getting off the KTX, follow the metro signs. Daejeon Station provides access to Daejeon Metro Line 1. For the exact walking route, check the on-site maps and Daejeon Transportation Corporation's station guide.

1. Find the metro station closest to your final destination.
2. Check the route from Daejeon Station to the metro platform.
3. Check the direction of travel and service times before boarding.

If you need an elevator, ask about an accessible route first. This article does not specify an exit number or a fixed transfer time. Check service information with Daejeon Transportation Corporation.

Traveling from Osong Station to Sejong

For the Government Complex Sejong area, check BRT routes B1, B2, and B3. These routes are listed in the Ministry of Science and ICT's transport guide. The listed stop to get off at is Government Complex Sejong North.

1. Check the exact address of the institution you are visiting and the nearest stop.
2. Look up the relevant route through Sejong Urban Transport Corporation or the bus information system.
3. Check the boarding location at Osong Station and the bus's direction of travel.
4. Check bus service times after your train's arrival.

The source is the Ministry of Science and ICT's Directions Guide. Recheck BRT fares, service intervals, and last-bus times for your travel date. The appropriate stop also changes depending on your destination within Sejong.

Checking Parking, Luggage Lockers, and Nursing Rooms

Decide which station facilities you need and check them before departure. Parking fees and facility operating status require up-to-date information. This article does not list unverified fees, floor numbers, or exit locations.

For rail-related inquiries, contact the customer service center at 1588-7788. Identify the parking facility by name before checking its fees. For rental cars, go to the vehicle pickup location shown on your booking screen.

Comparing Arrival Times and Total Transport Costs

Choose your station by comparing the time and cost of reaching your final destination. Travel and waiting time remain even after you get off the train. Use the table below to compare actual search results.

For a visit to Sejong, compare options using the address of the building you will visit. For a visit to Cheongju, you must also calculate travel after arriving at Osong Station separately. If driving, include parking fees in your total transport cost.

Common Mistakes When Booking and Changing Tickets

Distinguishing station names, segments eligible for discounts, and change conditions can reduce booking errors. In particular, do not treat Daejeon Station and Seodaejeon Station as the same station. Reread the departure and arrival stations on your ticket just before paying.

• Do not go to Seodaejeon Station with a ticket for Daejeon Station.
• Not every high-speed train stops at Osong Station, even though it is a junction.
• Do not use the average 10% reduction as a formula for calculating individual route fares.
• Do not apply the 30% transfer discount to the total journey cost.
• Do not assume your ticket has been issued just because you can see your reservation details.

Ticket changes are possible within 7 days before or after the travel date. Changes without a fee are allowed until 30 minutes before departure. This is based on Korail's integrated operations announcement of August 5, 2026.

Do not confuse the change-fee waiver with cancellation and refund conditions. You must check seat availability for the train you want to change to in Korail+. Also check any additional payment or refund amount shown on the change screen.
