Transantiago bus, with original color scheme (2005–2012)Transantiago is the name for the city's public transport system. It works by combining local (feeder) bus lines and main bus lines, as well for the EFE commuter trains and the Metro network. It includes an integrated fare system, which allows passengers to make bus-to-bus, bus-to-metro or bus-to-train transfers for the price of one ticket, using a contactless smartcard (bip!). This system also offers reduced fares for the elderly, as well as high school and university students.
