MRT-3 runs from north to south. The current north terminal is North Avenue in Diliman in Quezon City to Taft Avenue in Pasay City.

Platform A goes towards North Avenue while Platform B goes towards Taft Avenue. Please see Philippine Tech for equipment and fare control information for the MRT-3. Each station has a bag and person inspection policy where one cannot enter each station without their bags/purses/packages being inspected, in addition to their person being patted down. This was largely in response to the Rizal Day bombings on 12/30/00.

Women with children(male and/or female) may elect to ride in the women's car or in the other cars.
