T1 (Istanbul Tram)

T1 Kabataş - Bağcılar tram line (Turkish: T1 Kabataş - Bağcılar tramvay hattı) is a tramline of the Istanbul Tram and is operated by Metro Istanbul. It runs south from Kabataş to Bağcılar via Eminönü, with a total length of 18.5 km (11.5 mi).

The first section of the T1 line opened between Aksaray and Beyazıt on 13 June 1992 and was later extended first to Topkapı and Zeytinburnu, and later to Eminönü. On 29 June 2006, the Eminönü-Kabataş extension was opened, making the transfer to Kabataş–Taksim funicular possible. On 3 February 2011, it was fused with the T2 line that was opened in 2006 between Zeytinburnu and Bağcılar by converting T2 line's stations to low-floor tram stations.
