Passengers on the 1.8-kilometre Gold Line monorail will be charged 15 baht per trip starting from Saturday, according to Krungthep Thanakhom.
The flat fare takes effect after a month of free services offered by the operator to promote the system, said Kriangphol Pattanarat, managing director of Krungthep Thanakhom, the business arm of the Bangkok Metropolitan Administration.
The driverless monorail system, with three stations, runs from the Krung Thon Buri interchange with the BTS skytrain to the Charoen Nakhon and Klong San stations in front of Taksin Hospital.
Mr Kriangphol said the number of Gold Line passengers had averaged 10,000 per day since it opened on Dec 15. But the new outbreak of Covid-19 has reduced the number to about 3,000 per day as many people are avoiding going out or are working from home again.
The Gold Line was not part of the original mass transit master plan for the capital. It was proposed by the owners of Iconsiam in 2015 to provide a feeder service to the giant shopping centre on the west side of the Chao Phraya River.
Krungthep Thanakom handled the design and development of the line.
The project cost of 3.8 billion baht was fully funded by Siam Piwat, the owner of Iconsiam. It will collect all advertising revenue and operating profits during the 30-year concession period.
