The Mass Rapid Transit Authority of Thailand was established in 1992 under the name Metropolitan Rapid Transit Authority, under the Royal Decree Establishment of the Metropolitan Rapid Transit Authority B.E. 2535, with the objective of organizing mass transportation systems in Bangkok and its vicinity by electric train.[2][3]

On 1 December 2000, under the Mass Rapid Transit Authority of Thailand Act B.E. 2543, the name was changed to Mass Rapid Transit Authority of Thailand.

Under the act, the MRTA has the authority to designate "safe zones" to protect subway tunnels and underground structures and oversee the metro system as a whole. In addition, the MRTA is able to find income other than passenger fares and can develop real estate as necessary for the benefit of the electric train service and has the authority to operate the electric train business. The transit system may expand to other provinces as the royal decree authorizes.[4]
