As well as the highly popular Istanbul Metro line, there is also the Light Metro line. This is made up of just two different lines, and connects many different parts of the city. The first line was opened back in 1989, and offers services between Kartalepe and Aksaray. The line was then modernised back in 2002, and reached Ataturk Airport.
The later line, the T4, was only opened five years ago, and runs between Mescid-I Selam and Eddirnekapi. There are 36 stations in total, 12 of them being underground and three being viaduct stations. The line is 32km in length, making it long enough to provide efficient transport across many parts of the city. The Light Metro lines are completely separated from other forms of transport in the city, too, meaning that there simply aren’t any hold ups when you’re travelling. The services and vehicles were built in 1989, but today run as efficiently as ever.
