There is a good chance that the Purple Line servicing from Tao Poon – Bang Tao will be ready for the public ahead of the schedule in August 2016. The test run will commence on the 14th December until January 2016 when the public test run begins for the next two months. If all is satisfied the Purple Line will be on fully service to the public. However, the management of the service whether by the government or public company is still under discussion.
