SolFest 2026 Runs 17 to 19 December in Nairobi

Bangkok's Mass Rapid Transit Authority (MRTA) anticipates the eastern segment of the Orange Line to commence trial public services in December 2027, with full paid operations starting in January 2028. MRTA Governor Kanchapoj Udomthamphakdee revealed that construction of the eastern segment, stretching from the Thailand Cultural Centre to Min Buri (Rom Klao intersection), is being expedited.

The inaugural train is slated to arrive in November 2026, followed by the rest by May 2027. The eastern segment will undergo about six months of system testing and trial operations prior to the public trial phase. In contrast, the western section connecting Bang Khun Non with Thailand Cultural Centre is still under civil construction and projected to open in 2030.

Additionally, the southern Purple Line is progressing on schedule, with civil construction planned to conclude by year-end 2027. However, the project's investment model and financial projections are currently under review to comply with government fare policies and prepare for project responsibility transfer. Approval for the investment model is anticipated by late 2026, followed by submission to the Cabinet and investor selection.

Full Purple Line operations are expected in 2030, with potential trial runs in stages. MRTA is also preparing to assume management of the Green, Gold, and Red lines from the Bangkok Metropolitan Administration and the State Railway of Thailand, respectively, as part of a government initiative to unify urban rail operators. This integration aims to streamline responsibilities, enhance efficiency, and streamline rail travel.

Preparatory efforts encompass coordination between agencies and drafting memorandums of understanding for legal frameworks. Three additional Bangkok rail projects — the Brown Line, Silver Line, and first phase of the Grey Line — are currently undergoing feasibility study reviews to accommodate evolving economic and social factors.

The Brown Line, spanning 22.1 kilometers from Khae Rai to Lam Sali, is awaiting integration with the Chalong Rat–Khae Rai expressway plan. The Silver Line, connecting Bang Na with Suvarnabhumi Airport, and the first phase of the Grey Line, running from Watcharaphon to Thong Lo, are both slated for 2033. Meanwhile, tunnel repairs near Vajira Hospital and water seepage issues near Wongwian Yai are expected to be resolved by October 2027, with road surfaces fully restored within two to three months.
