The Brown Line, Bangkok’s third monorail mass-transit project linking Nonthaburi province and the city’s eastern zone, could be available for service by late 2028 if things go as planned, a Transport Ministry source said on Friday.

The Mass Rapid Transit Authority of Thailand (MRTA) is expected to call for bids to construct Bangkok’s Brown Line from Khae Rai to Lam Sari in 2023, said MRTA governor Pakapong Sirikantramas.
