The city is also served by the Qinhuangdao–Shenyang high-speed railway, the main passenger transport corridor in and out across the Shanhai Pass, and the first passenger-specific railway line in China. In early 2007, a 200 km/h (120 mph) high-speed train decreased travel time between Beijing and Shenyang by almost three-fold to around 4 hours. The Harbin–Dalian high-speed railway opened in late 2012 and connects Shenyang with other major cities in Northeast China such as Harbin, Changchun and Dalian at speeds of up to 300 km/h (190 mph).[94]
