BEIJING - China's railway authority is about to suspend two pairs of bullet trains on part of the Beijing-Shanghai high-speed railway because of their low occupancy rate.

Two shuttle trains to Jinan, in Shandong province, one from Beijing, the other from Tianjin, will be "temporarily halted" starting Monday, according to a notice on the Tianjin Railway Station's website on Wednesday.

This is the first time railway authorities have announced a reduction in service since the flagship 1,318-kilometer Beijing-Shanghai railway, the world's longest fast track, opened late last month.
