Istanbul inaugurated horse trams in 1872 and these served the people of Istanbul until 1912. Following this date, electric trams were put in place and they were the main means for urban public transport until 1966. Many routes were built step by step, and it reached their most widespread network in 1956 with 108 million passengers in 270 shuttles in 56 lines. Tramcars were not modernized for many decades, and some of the 1911 electric cars were still running in the 1960s. At that time modern buses provided faster and smoother journeys. Because of those negative issues, tram system closed in mid-1960s.
