The Transport Ministry is considering piloting a 15 baht flat-rate fare, which is estimated to require at least 700 million baht in subsidies per year, on three electric train routes, according to two service operators.

The Tao Pun-Bang Yai section of the Purple Line and the Airport Rail Link are most likely to be picked for the pilot phase of the ministry's policy to cut the cost of travelling by electric train, said Mass Rapid Transit Authority of Thailand governor Pakapong Sirikantaramas.

"These two routes are operated by the government and do not have legally binding agreements with any private parties," he said.

The government already subsidises the Purple Line at a cost of about 1 billion baht a year, according to Mr Pakapong.

Another route that is seen as suitable for piloting a flat rate fare is the Red Line's Bang Sue-Rangsit section which is due to begin operating by 2021, according to Mr Suthep.

The Airport Rail Link carries about 90,000 passengers per day while the Purple Line serves about 50,000 per day, according to the ministry, while the Red Line is expected to have between 70,000 and 100,000 passengers per day.
