Blue Bus:

This type of buses will operate at higher speeds and access the median bus lane connecting suburban areas to downtown Seoul. The city government is partly in charge of its operation. The city has taken full consideration to introduce 3 kinds of buses belonging to the Blue Bus category: bendable bus, CNG (compressed natural gas) bus with a lower platform, and regular large-sized CNG bus. The blue color represents Seoul's skyline and Hangang (River) to symbolize security and freedom.

Green Bus:

Green bus will be flexibly operated by private bus companies, to connect major subway stations or bus terminals in downtown Seoul. It is similar with the city bus and the community shuttle bus currently in operation. Green stands for the mountains surrounding the city.

Red Bus:

The red buses will be express buses designed specially for those commuting between downtown Seoul and the metropolitan area. The color red exudes energy of speed.

Yellow Bus:

This bus will circle downtown Seoul and stop at stations for blue buses and major railway stations, as well as business, tourist and shopping areas. Yellow was selected for its dynamic and friendly image.

Transportation Card

The simplest means of paying for transportation in Seoul is using the transportation card. 

T-Money Cards are sold at subway stations.

T-Money card can be used to receive discounts when transferring between buses and subways to reach a destination. Passengers should pass their transportation card or T-money over the read machine until a beep is heard when getting on and off a bus or the subway. If you fail to scan your card as you get off a bus or the subway, you will not be able to take advantage of the transfer discount.

After getting off the bus or subway, a passenger has up to 30 minutes to transfer to another bus or the subway to get the transfer discount. This is extended to one hour between 21:00 to 07:00. This means that passengers only have to pay the 800 won boarding fee once, no matter how many times they change between buses and subways, with an increment of 100 won charged for every additional 5 km (bus) or 6 km (subway). No discounts are available when using cash or single ride tickets.
