The train, made by a subsidiary of CSR Corp Ltd,China's largest train maker, is designed to resemble an ancient Chinese sword, the official Xinhua news agency reported.
It "will provide useful reference for current high-speed railway operations," it quoted train expert Shen Zhiyun as saying.

China's railway industry has had a tough year, highlighted by a collision between two high-speed trains in July which killed at least 40 people. Construction of new high-speed trains in China has since been a near halt.
In February, the railways minister, Liu Zhijun, a key figure behind the boom in the sector, was dismissed over corruption charges that have not yet been tried in court.
