Comparing departures from Yongsan, Seoul, and Suseo

Choose your departure station based on both the time it takes to get there from home and the available trains. With integrated operations starting on September 1, 2026, the SRT name changed to KTX-Sancheon. You can also look up departures from Suseo in Korail+. Korail announcement on integrated high-speed rail operations

The announcement of additional services at Seoul Station covers the Gyeongbu, Gyeongjeon, Donghae, Honam, and Jeolla lines together. The 13 additional weekday services and 14 additional weekend services are totals across these lines. Do not use these figures as the daily number of services to Gwangju Songjeong or Mokpo alone.

When changing your departure station, search again using the same date and passenger count. Compare services from each station to your intended destination. Do not use search results for Gwangju Songjeong as a substitute for results for Mokpo.

KTX fares to Gwangju Songjeong and Mokpo

The confirmed base fare from Yongsan to Gwangju Songjeong after the reduction is 42,000 won. This applies from September 1, 2026. The actual amount you pay varies by train, date, seat, and discount conditions.

Korail announced an average fare reduction of 10%. This does not mean fares on every route fell by exactly 10%. Do not assume that 42,000 won applies to every seat and age group, either. Korail fare reduction announcement

Discounts and mileage points

Check eligibility for mileage points and transfer discounts separately. The KTX member mileage accrual rate in the integration announcement is 5%. When connecting to a conventional train, the transfer discount is 30% of the conventional train fare.

• Mileage points: Check in Korail+ whether you qualify to earn points as a railway member.
• Transfer discounts: Check the applied discount details when connecting to a conventional train.
• Seat and passenger discounts: Check which conditions are available for your train.

Do not apply the conventional train transfer discount rate to the entire KTX fare. Do not count mileage points earned as a discount deducted immediately at payment. Check the actual benefits in the details of your selected ticket.

Fare difference calculation example

The difference between the announced Yongsan to Gwangju Songjeong fares is 4,800 won. This is the result of subtracting the reduced fare of 42,000 won from the previous fare of 46,800 won. The calculations below do not reflect additional discounts or seat changes.

Approximately 10.26% is the rate for this route, calculated directly from the two fares. Its calculation covers a different scope from the overall average of 10% announced by Korail. To work out your actual savings, compare tickets with the same conditions.

The Honam High-Speed Line and the route to Mokpo

Beyond Gwangju Songjeong, trains currently use the existing Honam Line to reach Mokpo. The new section of Honam High-Speed Railway Phase 2 is under construction. The fact that KTX trains run to Mokpo does not mean the entire route is a high-speed line.

The Honam High-Speed Main Line in Korail’s operating network is 183.8 km long. It runs from Osong to Gwangju Songjeong. The conventional Honam Line runs 252.5 km from Daejeonjochajang to Mokpo. Both figures are current as of September 1, 2026. Korail passenger train operating information

Osong, Gongju, Iksan, Jeongeup, and Gwangju Songjeong are stations on the Phase 1 section. Not every KTX train stops at all these stations. Also check your selected train’s stops to see whether it runs via Seodaejeon.

When will Honam High-Speed Railway Phase 2 open?

The project period listed by Korea National Railway is 2015 to 2027. As of September 2026, construction progress is 61.0%. The final year of the project period alone does not establish the actual opening date.

• Gwangju Songjeong to Gomagwon: The existing line is being upgraded for higher speeds.
• Gomagwon to Imseong-ri: A new high-speed railway section is being built.
• Imseong-ri to Mokpo: This section uses the existing line.

The Phase 2 station plan includes Naju, Muan Airport, and Mokpo. Muan Airport Station has not yet opened. Naju Station and Mokpo Station are currently in use. Korea National Railway major high-speed rail project status

How to get from Gwangju Songjeong Station to central Gwangju

To reach central Gwangju, check connections to Gwangju Metro Line 1. From Gwangju Songjeong Station, you can take trains toward Sotae and Nokdong. Sangmu, Geumnamno 4-ga, and Culture Complex stations are among those on the same line. Gwangju Transportation Corporation Cyber Station

1. After leaving the KTX train, follow the signs to Gwangju Songjeong metro station.
2. Find the metro station closest to your destination.
3. Check the stops of the relevant train toward Sotae or Nokdong.
4. If you arrive late, check the last metro train and other transportation options.

Gwangju Transportation Corporation provides elevator information for Gwangju Songjeong metro station. This is separate from information on facilities throughout the KTX station. If stairs are difficult for you, also check the route between the two stations.

Onward transportation from Mokpo Station

After arriving at Mokpo Station, choose a bus or taxi based on your final destination. For Namak or Oryong, you can check the Allta 2001 bus service listed by Mokpo City. Recheck the boarding location and operating times on your travel date. Mokpo City Allta 2001 service information

If you are continuing toward Boseong or Suncheon, also look up conventional trains. The Mokpo-Boseong Line began operating on September 27, 2025. The opening announcement lists Saemaeul-ho and Mugunghwa-ho services. Do not assume that your KTX train continues all the way to Boseong. Korail Mokpo-Boseong Line service information

Checking parking, luggage lockers, and nursing rooms

Before visiting, check the location and availability of any station facilities you need. Do not assume that Gwangju Songjeong Station and Mokpo Station have the same facilities or conditions. It is best not to base your plans on unverified parking fees or locker locations.

In January 2025, Korail announced improvements to the existing EV chargers at Gwangju Songjeong Station. This announcement alone does not tell you whether charging will be available on the day of your visit. If you are driving, also check the charging facility operator’s information. Korail announcement on EV charging facility improvements

For station facility inquiries, contact the Railway Customer Center at 1588-7788. The Korail website also lists 1544-7788. When making an inquiry, provide the station name and the facility you need.

How to compare total travel time rather than just train time

When choosing a departure station, compare the total travel time from home to your destination. Even if the KTX ride is shorter, a long trip to the station can reduce the advantage. Include transfer waiting times after arriving at Gwangju Songjeong or Mokpo.

1. Search for departures from Yongsan, Seoul, and Suseo using the same arrival station.
2. Add travel time outside the stations for each available service.
3. Check whether you can make the last connection or arrive in time for your appointment.
4. Choose by comparing both total transportation costs and the effort involved in the journey.

Common mistakes when reading timetables

Distinguish construction project figures from actual ticket information. The length of an entire line also differs from the distance you personally travel. The following items need to be checked again on the booking screen.

The 820 seats refer to the trial operation coupling SRT and KTX-Sancheon trains. At the time, the Honam Line services involved were some weekend trains between Suseo and Gwangju Songjeong. Check the seat selection screen for your chosen train for current seating information. Korail announcement on trial coupled operations

You should also distinguish reports about a possible fare increase from announcements that an increase will actually take effect. On March 7, 2025, Korail stated that the rate and timing of an increase had not been decided. Base your travel budget on the price shown on the booking screen rather than speculation about increases.
