Tickets

Tickets can be purchased at stations from machines, and at major stations from ticket windows.

When you purchase your ticket, you will need to validate it as you enter the station. The station has automatic gates that open after you insert a ticket. The ticket is stamped, and you need to take the ticket to open the gate and enter the station.

Keep your ticket with you whenever you are on the Metro. You need the ticket to exit the station (same procedure as getting into the Metro). Transfers between lines do not require additional tickets.
