Buses

Privately owned bus companies, regulated by the city, also operate on major routes. These private buses may accept cash or electronic transit pass.
Metro
Istanbul’s metro network has eleven lines including: the M1 linking Yenikapı to Aksaray Square; the M2, connecting Sishane and Haciosmanm, through commercial areas; the M3 serving Basaksehir, Kirazli and the Olympic Village; and the M4, on the Asian side, running from Kadikoy to Kartal along the Sea of Marmara.
Funicular
The funicular connects Kabataş on the European Bosphorus shore to Taksim Square, Beyoğlu’s bustling hub. This short underground tram links the Bağcılar-Kabataş tram and the Kabataş ferry docks to the Metro and Nostalgic Istiklal Caddesi tram at Taksim Square, making it a vital part of Istanbul’s transport system.
