What is "tunel"

The Tünel is a short underground railway line in Istanbul, Turkey. It is an underground funicular with two stations, connecting the quarters of Karaköy and Beyoğlu. Located at the northern shore of the Golden Horn, the underground railway tunnel goes uphill from close to sea level and is about long. Inaugurated on January 17, 1875, the Tünel is the second-oldest extant subterranean urban rail line in the world, after the London Underground (1863) and an 1862 line in Lyon that is no longer in operation. It is thus the oldest surviving underground urban rail line in continental Europe.

Túnel is the third studio album released by Puerto Rican rock band La Secta. The album was released in 2003 by Universal Latino.

Tunel ( Serbian Cyrillic: Тунел, trans. Tunnel) was a Yugoslav rock band from Belgrade.
