As of 2012, Sanya railway station functions primarily as the southern (Sanya) terminal for the D-series (EMU) trains of the
Hainan Eastern Ring High-Speed Railway, which travel between Sanya and
Haikou on a fairly frequent schedule. In addition, Sanya Station is also the terminal for the "conventional" trains arriving to Sanya from Haikou along the
Hainan Western Ring Railway. As of the late 2012, however, such trains are few; in fact, schedule sites reports only one such daily train, T201/T204 from
Beijing West (via the Hainan Ferry and Haikou). Sanya railway station is also the end point of the
Hainan Western Ring High-Speed Railway, thus becoming the point where the high-speed rail ring around the island is closed. A short section of the Western High-Speed Ring, from Sanya railway station to the
Phoenix Airport railway station 10 km to the west was completed first, by the end of 2014. ==Notes==
