Constructed near the beginning of the 20th century, until 2014 the Cairo tramway network was still used in modern-day Cairo, especially in modern areas, like Heliopolis and Nasr City. During the 1970s, government policies favoured making space for cars, resulting in the removal of over half of the 120-kilometre (75 mi) network. Trams were removed entirely from central Cairo but continued to run in Heliopolis and Helwan.
