T6 (Istanbul Tram)

The T6 Sirkeci–Kazlıçeşme Tramway Line or U3 Sirkeci–Kazlıçeşme Rail Line (Sirkeci – Kazlıçeşme Raylı Sistemi/Tramvay Hattı) is a tram line, rail line or light rail line that operates between the Sirkeci Terminal and Kazlıçeşme Station.

The T6 line uses approximately 8.3 km of track previously used by the Istanbul Sirkeci-Pythio Railway and Istanbul suburban closed since August 12, 2013 as part of construction of the Marmaray, running on refurbished tracks through Sirkeci and Kazlıçeşme. The line currently uses repainted TCDD E32000 units used on the Marmaray line, but is expected to have modernized nostalgic tram vehicles.

With the completion of this project, it is once again possible for regional and international trains to depart from Sirkeci as before, and for trains carrying dangerous goods that could not use the Marmaray Tunnel to be transported from Sirkeci to Haydarpaşa by train ferry.

The line is defined as a rail line by the Ministry of Transport and Infrastructure, but defined as a light rail or tram system by the Istanbul Metropolitan Municipality (IMM).
