Beijing will further expand its subway system with the opening of three new lines on Saturday. After the launch, Beijing will have 22 metro rail lines spanning 608 kilometers. The 10.2-kilometer S1 Line will be Beijing's first medium-low speed maglev line, and has a top speed of 100 kilometers per hour. It will link the city's western districts of Mentougou and Shijingshan, and passengers can ride the entire line in less than 20 minutes.  As we just heard, the Yanshan-fangshan Line is China's first fully domestically developed automated subway.

It has nine stations on its 14.4-kilometer main line. The line is expected to carry 70,000 passengers daily. Beijing's first modern tram will also welcome passengers on Saturday. It will operate in Haidian district on the city's west side. Known as the Xijiao Line, it will be popular for sightseeing because it passes eight attractions, including the Summer Palace, Beijing Botanical Garden and Fragrant Hills Park. It runs mainly at ground level, but rises or goes underground as the road system requires.
