The Bangkok Metropolitan Administration (BMA) will transfer the responsibility for three rail projects in Thailand, with a combined cost of THB150 billion, to the Mass Rapid Transit Authority (MRTA). This includes the Grey Line Monorail connecting Watcharapol and Thong Lor, the Silver Line light rail transit (LRT) system connecting Bang Na to the Suvarnabhumi Airport, and the BTS Skytrain Green Line extension from Bang Wa to Taling Chan.
A proposal to transfer the three Bangkok rail projects will be presented to the Commission for the Management of Road Traffic. Following close consultation, MRTA will take full responsibility for investment planning and contract management.
The BMA has completed studies for the Grey and Silver lines, which are both expected to be built through a public-private partnership (PPP) model under a 30-year concession contract. The Green Line extension project is in the development phase following an earlier value study.
