A bullet train runs during a trial operation on the East Ring Railway, or Donghuan Railway linking Haikou, capital of South China's island province Hainan and Sanya City, Dec 26, 2010. Built with a total investment of 20.2 billion yuan (about US$3 billion), the railway skirts along the eastern coast of the island spanning a length of 308 kilometers. The trip between the two cities will take only 90 minutes, half the time of a trip by road. The railway will be put into use at the end of December or the beginning of January. [Xinhua]
