The Pink Line will start its trial run on Tuesday, with free rides to be offered to passengers in September and October, said the Mass Rapid Transit Authority of Thailand (MRTA).
The Pink Line will offer free rides for the next two months before opening as a commercial service in November. The opening comes earlier than planned.
Construction of the MRTA's Pink Line, linking Khae Rai Station at one end to Min Buri Station on the other, has been underway since 2016, with the government helping the MRTA with the land appropriation.
The 34.5-kilometre-long monorail line starts at Nonthaburi Civic Centre Station, which is connected to the MRT Purple Line, and ends at Min Buri Station, which will be connected with the Orange Line that is currently under construction.
Meanwhile, also starting on Tuesday, services along the State Railway of Thailand's (SRT) Red Line will begin earlier, with the first trains leaving the depot at 5am instead of 5.30am.
