F3

The F3, also known as the Vadistanbul Skyrail and officially referred to as the F3 Vadistanbul-Seyrantepe funicular line, is a long funicular railway in Sarıyer, Istanbul. The line is one of four funicular railways in Turkey, all of them in Istanbul, and is the only one that operates above ground. Due to the fact that the F3 runs along a concrete viaduct, it has been advertised as a Monorail even though it is technically a funicular railway. The route runs between Vadistanbul and Seyrantepe, where connection to the M2 line is available.
