If you're planning to travel from Seoul to Busan for the first time, chances are you've already heard of KTX. It's Korea's most famous high-speed train and the option most travelers discover first.
But after a little more research, you'll probably come across another train called SRT.
That's usually when the confusion begins.
Both KTX and SRT connect major cities across South Korea, including Busan, Daegu, Daejeon, and Mokpo. Both are modern, comfortable, and widely used by locals every day.
As a result, many international travelers end up asking the same question:
"What's the difference between KTX and SRT, and which train should I take?"
The answer is actually simpler than most people expect.
When comparing KTX and SRT, three factors matter most:
- Which station you depart from
- The ticket price
- How long it takes to reach the station from your hotel
In other words, the best train isn't necessarily the fastest one. It's the train that fits your travel route most efficiently.
Why Does Korea Have Two High-Speed Trains?
Many foreign visitors are surprised to learn that South Korea operates two separate high-speed rail services.
KTX is operated by Korail, Korea's national railway company. SRT, on the other hand, is operated by a separate railway company called SR.
The biggest difference between the two is not speed or onboard facilities. It's where they depart from in Seoul.
KTX primarily departs from Seoul Station and Yongsan Station, while SRT departs from Suseo Station, located in southeastern Seoul.
Because both trains serve similar destinations, many travelers assume one must be faster or better than the other.
However, in real-world travel, the station location often matters far more than the train itself.
If you're staying near Myeongdong, Hongdae, Jongno, or Seoul Station, KTX is usually the more convenient choice.
If you're staying in Gangnam, Jamsil, Seolleung, or other southeastern areas of Seoul, SRT may save you significant travel time before your journey even begins.
KTX vs SRT: What Actually Matters?
Many comparison articles focus heavily on technical specifications, train models, and performance figures.
For most travelers, however, the decision is much simpler.
1. Departure Station
The location of your departure station can have a greater impact on your trip than a small difference in ticket price.
Even if a ticket is slightly cheaper, spending an extra hour reaching the station may not be worth it.
2. Booking Platform
KTX tickets are purchased through Korail's booking system.
SRT tickets are purchased through the separate SRT reservation system.
Because the two services are operated by different companies, SRT tickets cannot be booked through Korail.
3. Total Travel Time
Many travelers only compare train travel times, but the journey to the station should also be considered.
In many cases, station accessibility affects the overall travel experience more than the train itself.
KTX vs SRT Price Comparison
Ticket price is one of the most searched topics when travelers compare KTX and SRT.
Generally speaking, SRT is slightly cheaper than KTX on the same route.
However, the difference is usually small.
On the Seoul to Busan route, the price gap is often only a few thousand Korean won.
Because of this, it's important to look beyond the ticket price and consider transportation costs and travel time to the departure station.
A cheaper ticket doesn't always mean a cheaper overall journey.
KTX vs SRT Speed Comparison
Another common question is whether one train is faster than the other.
In reality, the difference is minimal.
Both KTX and SRT are high-speed rail services and offer very similar travel times on major routes.
The actual journey time often depends more on train schedules and the number of intermediate stops than on the train brand itself.
For most travelers, convenience matters far more than a small difference in speed.
KTX vs SRT Stations: Where Do They Depart?
The most important difference between KTX and SRT is their departure stations in Seoul.
KTX Departure Stations
KTX primarily departs from Seoul Station, Korea's main railway hub.
It is especially convenient for travelers staying near:
- Myeongdong
- Hongdae
- Jongno
- Sinchon
- City Hall
KTX also serves major stations across the country, including Gwangmyeong, Yongsan, Daejeon, Dongdaegu, and Busan.
SRT Departure Stations
SRT departs from Suseo Station in Gangnam-gu.
Suseo Station is connected to Seoul Subway Line 3 and the Suin-Bundang Line.
It is often more convenient for travelers staying near:
- Gangnam
- Jamsil
- Seolleung
- Apgujeong
- Yangjae
SRT also serves destinations such as Dongtan, Jije, Mokpo, and Busan.
One of the most common misconceptions among foreign travelers is that all high-speed trains depart from Seoul Station.
SRT does not depart from Seoul Station.
SRT only departs from Suseo Station.

Where Is Suseo Station?
One of the most common questions from international travelers is:
"Where exactly is Suseo Station?"
Suseo Station is located in Suseo-dong, Gangnam-gu, Seoul and serves as the primary departure station for SRT trains.
If you're staying in Gangnam, Jamsil, Seolleung, or Apgujeong, Suseo Station may be significantly more convenient than Seoul Station.
However, travelers staying in Myeongdong, Hongdae, Jongno, or City Hall will usually find Seoul Station easier to reach.
That's why your hotel location should be one of the first things you consider when choosing between KTX and SRT.
Frequently Asked Questions
Is SRT cheaper than KTX?
Usually yes, but the difference is generally small.
Is SRT faster than KTX?

What is Suseo Station?
It is the main departure station for SRT trains in Seoul, located in Gangnam-gu.
Should I take KTX or SRT to Busan?
If you're staying near Seoul Station, KTX is usually the better option. If you're staying in Gangnam, SRT may be more convenient.
Why can't I find SRT on Korail?
Because SRT is operated by SR, not Korail, and uses a separate reservation system.
Which Train Should You Choose?
Choose KTX if:
- Your hotel is near Seoul Station
- You're staying in central Seoul
- You prefer Korea's main railway network
Choose SRT if:
- Your hotel is in Gangnam
- You're staying near Suseo Station
- You want to minimize travel time to the station
Ultimately, the decision is simpler than most travelers think.
It's not about which train is better.
It's about which station is closer to where you're staying.
For most travelers, that one factor will determine whether KTX or SRT is the smarter choice.
