Photo taken on April 18 shows CRH train D8834 (Urumqi-Turpan) at Urumqi South Railway Station in Urumqi, capital city of Xinjiang Uygur Autonomous Region. The train has slashed its intervals to just 30 minutes in the region's third system adjustment this year. The change aims to improve the quality of rail service for passengers. It is also seen as an important step in promoting the construction of the Silk Road Economic Belt.
