Airports Of Thailand PCLSilver Line extension connects to Suvarnabhumi Airport, potentially increasing passenger traffic for AOT.

The Mass Rapid Transit Authority of Thailand, or MRTA, has signed contracts hiring consultants to study the Silver Line rail project from Bang Na to Suvarnabhumi Airport and the Grey Line from Watcharaphon to Thong Lo. The studies will take about 12 months, and both projects are expected to be submitted to the cabinet for approval in 2028. Initially, both projects are expected to be developed under a PPP Gross Cost model, in which the public sector invests in civil works and bears all revenue risk, while hiring private companies to build the systems and manage the projects over the long term. For the Silver Line, the route has been extended to connect to the south passenger terminal of Suvarnabhumi Airport, following discussions with Airports of Thailand Public Company Limited. For the Grey Line, the study will examine convenient connections with other rail lines. MRTA has signed a contract with MHPM Company Limited as consultant to study and design the Grey Line Phase 1 from Watcharaphon to Thong Lo, worth 76.35 million baht, and hired Chotichinda Consultant Company Limited as consultant to study and design the Silver Line from Bang Na to Suvarnabhumi Airport, worth 75.70 million baht.
