Is the High Speed Train Service, (CRH) between Shenzhen/Xiamen Operating.

In fact, there is no direct trains between the two places, let alone the high speed train service.
I suggest you take a train to Dongguan, then transfer to another train to Shenzhen or Xiamen.

I dissagree with Jacks answer to my question, No ( High Speed Train Service, CRH, Shenzhen/ Xiamen.
I know for a fact that there is a High Speed Train Service between Shenzhen and Xiamen, the question is, "When will it be operating". It was to be in service sometime in July but, was delayed .

The CRH is still under construction and the operating time is not decided.
