The Thailand Consumers Council (TCC) is preparing to unveil a comprehensive study by August 2025 that explores four potential operational models for Bangkok’s Green Line once its current concession expires in 2029. The study, developed in collaboration with Sripatum University’s Legal Center, aims to support the continuation of the city’s THB20 flat fare policy while ensuring fair access to public transport.
Among the proposed options are: extending the current concession; initiating a new bidding process for operations; transferring operations to the Bangkok Metropolitan Administration (BMA); and shifting ownership to the Mass Rapid Transit Authority of Thailand (MRTA). The last option, favored by the BMA, is seen as financially viable due to significant non-fare revenues from property and advertising associated with the line.
While the Green Line’s concession ends in 2029, its management contract runs until 2042. The line is currently burdened with a debt of THB37.2 billion from operational and maintenance costs, which the study also seeks to address.
