Transportation in Town
City buses are called colectivos, or sometimes bondis in slang. There are 140 bus lines, many of which run along a variety of routes (ramales) through every city barrio. The service is very frequent -you will rarely have to wait more than five minutes during the day- and companies are obliged to provide all-night service, with at least one bus every half hour, although not every line complies. Bus fares are AR75 cents or AR80 cents for journeys within the capital, paid directly into the machine. Banknotes are not accepted so make sure you have change before you hop onto the bus.
Buenos Aires´ underground train network, operating since 1912, is called the Subte. It is the quickest, easiest and cheapest way to get around the city during the day, though it can be very crowded during morning and evening peak hours. The service runs from 5am to 10pm (8am to 10pm on Sundays). Large parts of the city are not served by the network, including some important tourist areas such as Recoleta and Palermo Viejo. A single journey to anywhere on the network cost just AR70 cents.
By taxi or remise:
Taxis in Buenos Aires are reasonable priced and plentiful (except in rainy rush hours). Traveling by taxi, however, has some risks and visitors need to be wary of being taken for a long ride. For this reason, it is recommended that you use a radio taxi or a remise (licensed minicab). You will need at least a few words of Spanish to call a radio taxi company, though staff in Hotels and restaurants will usually be happy to help.
ou are not expected to tip taxi drivers and they should give you change to the nearest AR10 cents. Change in the perennial problem with taxis. Anything larger than a AR$10 bill is guaranteed to produce a sigh, a AR$20 bill note may provoke a verbal complaint, and you are unlikely to find a driver if you only have a AR$50 or AR$100. Taxis are black and yellow (radio cabs included), with a red libre (free) light in the front window. Remises look like other private cars and do not run on meters. You should agree a price before setting off. Also, bear in mind that remises are often less punctual than radio taxis.
Trains connecting the northern suburbs with the city center are more modern -and safer- than those serving the south.
Trains linking the capital with destinations in Buenos Aires province, such as Mar del Plata or Tandil, are not in great shape, but they do have three classes. The main station serving the south is situated right in the middle of the red-light district in Constitución with a street address of 11 General Hornos street.
Trains run north and west from the Retiro station, which is actually three stations in one -known by their old names: Mitre, Belgrano and San Martin. The street address for the Retiro station is Ramos Mejía 1508.
