There are three lines colour-coded yellow, red and blue. The (oldest) yellow line runs between Vörösmarty tér and Mexikói út on the Pest side. The red line runs from the east of Pest through the inner city and under the river, ending at Déli Pályaudvar (the Southern Railway station). The (newest) blue line runs from the south-east of Pest and goes as far as the Pest end of the modern Árpád híd. All three lines cross the Deák tér junction, which is thus often a convenient point at which to begin and/or end walks on the Pest side, being situated close to museums and shopping centres. The Russian-built trains are appallingly noisy but clean and frequent. The metro runs between 4:30 a.m. and 11:10 p.m. The 100-Forint tickets (2001 Feb) are used for the metro also and must be validated in the automatic puncher situated at station entrances. They may be used for one hour on any one line; if you change lines a new ticket must be validated. Controls are quite frequent and ignorance of the rules is no excuse for travelling illegally. Ticket offices at stations sell 100-Forint tickets (trams, metro, trolley buses and buses).
