The Hainan western ring high-speed railway (Chinese: 海南西环高速铁路; pinyin: Hǎinán xī huán gāosù tiělù, often abbreviated [海南]西环高铁; [Hǎinán] Xī huán gāotiě^[1]) is a high-speed railway operated by China Railway Guangzhou Group in Hainan Province. It started operation on 30 December 2015.^[2]

The 344 km (214 mi) long rail line runs along the western half of the island's coastline, from Haikou railway station in the north to Sanya railway station. At its two end points, it connects with the existing Hainan eastern ring high-speed railway (opened in 2010), thus forming a high-speed railway ring spanning 653 km long, around the entire island, as well as the world's first and only circular high-speed railway line.^[3][4] The circular closed loop allows passengers to travel along the entire circumference of the island in approximately 3 hours at the shortest time, and connects all twelve coastal cities and counties, as well as having additional stops at Haikou and Sanya airports.^[5]

Unlike the Hainan eastern ring high-speed railway, which runs along the coast previously not served by railway (other than at its end points, Haikou and Sanya), the Western Ring high-speed railway roughly parallels the conventional-speed Hainan Western Ring Railway, which has connected Haikou and Sanya since 2005.

History

The Hainan western ring railway was constructed in two stages.

The first short section connects the existing Sanya railway station with the new Phoenix Airport railway station, 10 km (6.2 mi) to the west. The section has one intermediate station, Sanya West railway station (三亚西站). The construction work on this section (凤三段) was planned to be completed by the end of 2014.^[6]

On the rest of the railway - the much longer section from Sanya Phoenix Airport to Haikou - progress was only in its preliminary phase in 2012. Property was acquired, and demolition was conducted. According to the construction plans, 22,300 mu (14.8 km² or 5.7 sq mi) of land will be permanently used by the railway and associated facilities, and another 8,800 mu (5.9 km² or 2.3 sq mi) was temporary used during construction. Eighty-seven thousand m² of housing was demolished. The necessary demolitions were completed by the end of 2013.^[7]

In November 2015, the first test train travelled on the 344 km Western ring high-speed railway, and completed the 652 km circular railway loop around the island. The western ring high-speed railway became officially operational and open to the public in December 2015.^[8]
