The Metro in Mexico City is one of the most widely used metro systems in the world. It is ideal for a city with a large population and insufficient roads. It is quite popular with the locals, as tickets are very cheap (2 pesos per trip with the facility to transfer from one line to another). The metro is thus usually heavily crowded, which makes it stuffy and uncomfortable at times, but the speed and the effectiveness of the system compensate for the occasional discomfort.
Being in an overstuffed metro, it is best to keep a mindful eye on your possessions like purses and wallets. Pickpockets are not uncommon, and tourists are always quite alluring targets.
The metro runs from 5am to midnight (weekdays). The service starts at 6am on Saturdays and at 7am on Sundays.
The metro runs on 11 lines. Lines 1 and 7 are ideal for tourists as they pass through many of the city's attractions, giving a larger choice for sightseeing.
Ticket booths can have long queues, so it is best to buy more than one ticket at a time - they all cost the same.
The most striking feature of the Mexican metro is the fact that, as it was designed for a largely illiterate population, the system does not really rely on multilingual signs. Instead, routes, signs, warnings, and almost everything is marked by color codes and easily understood symbols and icons. However, here are a few basic terms you should familiarize yourself with before you start using the Metro:
"??? Entrada - Entrance
"??? No Pase - Do not enter
"??? Salida - Exit
"??? Taquilla - Ticket booth
