A Beijing-bound bullet train running on the Beijing-Shanghai high-speed railway broke down again on July 13, 2011.

Hundreds of passengers transferred to another train to complete their journey.

This is the third delay within four days. Power failures previously halted 11 trains on July 10 and 29 others on July 12.

The latest train breakdown happened at about 10 a.m. at a stop in the city of Changzhou in Jiangsu Province, east China, according to the Shanghai Railway Bureau. The cause of the breakdown remains unknown.

The Beijing-Shanghai high-speed railway was put into operation on June 30. The 1,318-km-long high-speed rail line cuts travel time between the two metropolises to about five hours.
