It's the second metro in Saudi Arabia, following Mecca.
It's strange that Riyadh didn't have any metro system, though the city has more than 5 million people.
But, next year, 6 metro lines will open at the same time. It's also strange that the metro network is not extending gradually, but is scheduled to be born suddenly at one time.
