Do you know how many cities in the world use automated metro systems?

In 2013 there were 32 cities worldwide with automated metro systems and it is expected that this number will increase to 40+ by 2025. And all these cities adapted Grade 4 of automation, which is Unattended Train Operation (UTO) without staff on board.

Currently the 32 cities benefit from 48 automated metro lines which total 674 km and serve 700 stations! 40% of lines in located in Asia, 32% in Europe and the remaining in North America, Middle East and South America (only one city of Sao Paulo in Brazil). The average length of an automated metro line is 15 km, although the longest is Dubai (52 km) and the shortest in Hong Kong DRL (less than 10 km).

New automated lines are expected to open in the next 10 years in 10 new cities, including: Santiago de Chile (Chile), Sydney (Australia), Istambul (Turkey) or Helsinki (Finland).
