Korean trains come in 6 types with different travel speeds: KTX, Saemaeul, Mugunghwa, Nuriro, ITX, SRT.

• KTX: KTX is used by passengers who want to travel quickly between most major cities in Korea. KTX, which can run at a speed of 305 km with a total of 20 cars and 935 seats, is the fastest train in Korea.
• Saemaeul: Saemaeul is KORAIL's medium- to long-distance railway line operating only on the Janghang Line, which is a non-electrified section.
• Mugunghwa: The Mugunghwa railway line is named after the Rose of Sharon, Korea's national flower. It is the slowest among trains, operating mainly at stations where KTX and Saemaeul trains do not stop.
• Nuriro: Nuriro is in the same class as the Mugunghwa. It started to be operated in 2009, currently carrying passengers between the Janghang Line and the Chungbuk Line.
• SRT: SRT started operation in 2016, operating the Gyeongbu High-Speed ​​Line and Honam High-Speed ​​Line. It is operated by SR.
• ITX Youth Train: This train began operation in 2012, running only from Yongsan, Seoul to Chuncheon, Gangwon-do and sharing many stations with the Seoul subway.

Public transportation can be conveniently accessed in all regions in Korea.

• City bus: Regardless of the city size, city buses can be used in almost all regions in Korea. However, the operating system varies by region, so there are differences in the number of stops and fares.
• Subway: Subway lines are operated by Seoul, Busan, Daegu, Incheon, Daejeon, and Gwangju. The routes are so diverse that a person can go practically anywhere in the Seoul metropolitan area by just using subways.

In Korea, there are many city bus lines and subway lines to choose from. However, all the routes are based on a transfer system where passengers are allowed to transfer up to 4 times without additional charges if they do so within a designated time period (30 minutes or 1 hour). Using this system enables traveling to distant destinations at a lower cost.
* However, additional costs apply depending on the travel distance.

In order to use this transfer system, passengers must carry a card. Almost all Koreans use personal transportation cards or T-money cards and receive discounts on fares. Because one has to have a transportation card or a T-money card in order to use the transfer system, the card can be viewed as an essential element of using Korea's public transportation.
* To use the transfer, you must swipe your card on the terminal when getting off the bus.

Cash may be used to pay for public transportation fare, but very few people use it; and since one cannot use the transfer system with cash, a transportation card or a T-money card is highly recommended for people living in Korea.

There are trains in Korea that pass through various travel destinations.

1. 1. Regular taxis
   Regular taxis and deluxe taxis are the 2 types of taxis that carry passengers in Korea. They are distinguishable by the color of the vehicle or the text written on top of the vehicle.
   Taxis are painted in light yellow, white, silver, or black. Black taxis are deluxe taxis, and the other colors are regular taxis. Taxis can also have white or blue decoration on top of the car.
   A taxi with white decoration is a private taxi, and the one with blue decoration is a taxi operated by a taxi fleet company.
   
   Regular taxi: Basic fare (2km): 3,800 won | Additional charge (per 132m): 100 won | Late-night surcharge (24:00~04:00): 20%
   Deluxe taxi & large taxi: Basic fare (3km): KRW 6,500 | Additional charge (per 151m): 200 won | Late-night surcharge (24:00~04:00): None
   
   You can catch a taxi by simply waving your hand when a taxi approaches you and you see that it has an “Empty Car” sign on the box at the top of the taxi.
2. 2. International taxis
   As a foreign-language taxi service officially designated by Seoul City, the international taxi can be easily and conveniently used by foreigners visiting Seoul as well as foreigners residing in Seoul.
   If you are using the international taxi to go from Incheon Airport to downtown Seoul, there are designated areas in downtown Seoul where a flat taxi rate applies. Therefore, international taxis provide economic service for travelers to Seoul.
3. 3. Call taxis
   There is a wide range of mobile apps that could be downloaded and used for calling call taxis, with Kakao Taxi as the most popular call taxi app.
