The Zhengzhou–Xi'an High Speed Railway, also known as the Zhengxi Passenger Line (simplified Chinese: 郑西高速铁路; traditional Chinese: 鄭西高速鐵路; pinyin: zhèngxī gāosù tiělù), is a high-speed railway line connecting the cities of Zhengzhou and Xi'an, in the People's Republic of China. It went into operation on February 6, 2010.

The line is one of the segments of the future Xulan Passenger Dedicated Line, a high-speed mainline from Lanzhou to Xuzhou, paralleling the existing Longhai Railway line.

The densely populated corridor between Zhengzhou and Xi'an, both large regional centres, is home to some 100 million people. Its top speed is 350 km/h in operation, the minimum travel time between the two cities is 1 hour and 58 minutes, although in practice the journey takes two and a half hours with a few intermediate stops.[1]

When the high-speed line first opened, the trains departed and arrived at the "old" main train stations of Zhengzhou and Xi'an. Once the new Xi'an North Railway Station was opened all high-speed service in Xi'an was routed to it. In Zhengzhou now both the Zhengzhou Railway Station and the new Zhengzhou East Railway Station are served by high-speed trains from Xi'an.

The faster, G-series trains on the Zhengzhou-Xi'an Railway are numbered G20xx. Westbound trains (Zhengzhou to Xi'an) are odd-numbered, while even numbers denote eastbound trains (Xi'an to Zhengzhou).

With the opening of the Zhengzhou-Wuhan section of the Beijing–Guangzhou High-Speed Railway in the fall of 2012, direct high-speed service from Xi'an to Wuhan, Changsha, Guangzhou and Shenzhen was introduced.[2] It is expected that once the Beijing-Shijiazhuang-Zhengzhou section of the Beijing–Guangzhou line becomes operational at the end of 2012, direct Xi'an-Beijing service will become available as well.

The railway has made air service between Zhengzhou and Xi'an uncompetitive. All passenger flights between the two cities were suspended within 48 days of start of regular high-speed rail service.[3]

Construction[edit]

Construction work began on September 25, 2005, the railway opened for service on February 6, 2010.[4][5][6] CRH trains will run at 350 km/h (220 mph) on the line.

The main line is 456.639 km (283.742 mi) long, with another 27.879 km (17.323 mi) extension connecting existing Longhai Railway from Xi'an North to Xianyang West. Ten railway stations were built along the line: Yingyang South (not opened), New Gongyi, Luoyang Longmen, Mianchi South, Sanmenxia South, Lingbao West, Huashan North, Weinan North, Lintong East, and Xi'an North. The minimum railway curve radius is 9,000 metres (30,000 ft) for most of the line and 7,000 metres (23,000 ft) for some difficult sections. The distance between two parallel tracks is 5 metres (16 ft).

The line includes the 8,460-metre (27,760 ft) long Zhangmao Tunnel, 7,851-metre (25,758 ft) long Hanguguan Tunnel and the 7,685-metre (25,213 ft) long Qindong Tunnel. The line also includes the 79,732-metre (261,588 ft) long Weihe Grand Bridge, which, upon its completion, was the longest bridge in the world.[7]

Accidents[edit]

On November 14, 2009, a track inspection train seriously damaged 2,000 metres (6,600 ft) of the tracks near Huashan North Railway Station during a test run. The damaged section had to be removed and replaced. The railway was originally expected to be opened in December 2009, but the accident delayed the opening of the railway for at least one month.
