SHANGHAI, July 10 (Xinhua) -- A bullet train on the Beijing-Shanghai high-speed railway resumed operation after a breakdown for more than one hour due to electric power fault, local railway authorities said Sunday.

The Shanghai-bound G151 train broke down at about 6:10 p.m. in the section of east China's Shandong Province, according to the Shanghai railway authorities.

The train departed again at about 7:37 p.m. after rush repair.

An initial investigation into the accident indicated that electricity cutoff due to thunderstorms was to blame for the breakdown, according to the railway authorities.

By 10:30 p.m., a total of 11 trains on the railway line were delayed as a result of the breakdown.

Beijing-Shanghai high-speed railway was put into operation on June 30.

The 1,318-kilometer link, starting from Beijing and ending at Shanghai, cuts the single-way time between the two cities to less than five hours.

The railway is designed to be able to handle maximum train speeds at 350 kilometers per hour.
