BEIJING - A number of high-speed railway projects slated to open this year will have their big day postponed to next year or later, railway construction companies said.

A 200 km/h railway between Hefei and Bengbu in East China's Anhui province was set to be ready for operation by Nov 20 this year, but its debut has been postponed to next year, said an official with China Railway 4th Group Co Limited, insisting on anonymity.

"Work on the project is still on ... but on a small scale, not in full swing," he said.
