Bullet train attendants appear during an integrated test run of the Xinjiang-Lanzhou high-speed railway on Tuesday. The attendants for this railway are from multiple ethnic groups, primarily Han and Uygur. The railway that links Urumqi, capital city of Xinjiang Uyghur Autonomous Region, and Lanzhou, provincial city of Gansu, both of which are in northwest China, will be operational by the end of the year, marking the first-ever high-speed rail in Xinjiang.
