China Star (Simp. Chinese: 中华之星, a.k.a. DJJ2) is an indigenously designed experimental high speed train manufactured in China. It is a EMU train developed from the DJJ1 "Blue Arrow" high speed train by Zhuzhou Electric Locomotive Works.
It consists of 2 power cars and 9 passenger cars. The prototype rolled out in 2002. The train set is designed with completely independent intellectual property, for a top speed of 270 km/h (168 mph), and a full load of 726 passengers. It achieved a top speed of 321 km/h (200 mph) on the newly built Qinshen Passenger Railway during a test run in late 2002, setting a record Chinese train speed. However, due to signal system mismatch, fatal problems at electrical system and brake system, commercial service was delayed. The train entered into passenger service at Qinhuangdao-Shenyang PDL in 2005 but were limited to a top speed of 160 km/h (100 mph). Such problems still persists in service and the service was discontinued in 2006.
Shenyang RB ceased services offered by "China Star" from August 2006. As of 2007, the train was sealed and placed at an unsheltered parking area of the depot.
One of its power car and three passenger cars were moved to China Railway Museum, becoming the first high speed train being displayed in the museum.
