The idea for the railway was first proposed in February 1958 by then Vice-Premier and Director of the National Planning Commission,
Li Fuchun, during an inspection tour of Hainan. The original proposal was for a railway that would go completely around the island. It would incorporate several railway sections that had recently been, or were about to be, reconstructed in the southwestern part of the island (see
Hainan western ring railway). In February 1960, Premier
Zhou Enlai visited Hainan and created a construction blueprint. In May 1963, Li Fuchun returned to inspect Hainan. His intention was for a ten-year plan to complete the railway. This was interrupted by the
Cultural Revolution, and the plan was suspended. In the summer of 1980, the
State Council made the decision to speed up development and construction on Hainan Island. The Guangdong–Hainan Train Ferry (part of the
Guangdong–Hainan railway) was completed in December 2004, and the
Hainan western ring railway along the western coast of the island from Haikou to Sanya was completed in 2005. Preparation for the construction project in the eastern half of the island officially started in March 2006, with the
National Development and Reform Commission officially approving the feasibility report on March 22, 2007. Construction began on September 29, 2007, With a projected cost of over 22.22 billion
RMB (approximately US$3.3 billion) shared between China's
Ministry of Railways and the Hainan provincial government, this was Hainan's largest single investment project to date and employed a workforce of 50,000. The official opening and start of operations of the eastern ring railway took place on December 30, 2010 with a trial run. ==Trains==
