Mass Rapid Transit Master Plan in Bangkok Metropolitan Region
master plan for the creation of urban rail transit systems in Bangkok, Thailand
The Mass Rapid Transit Master Plan in Bangkok Metropolitan Region, or M-Map, is the latest version in a series of Thai government plans for the development of an urban rail transit network serving the Greater Bangkok area. It was drafted under the care of the Office of Transport and Traffic Policy and Planning (OTP) of the Ministry of Transport.
History
Lavalin Skytrain
Lavalin Skytrain Project is the earliest mass rapid transit plan of Bangkok to solve the traffic congestion in Bangkok during the 1970s. The project feasibility study was conducted by Thai Government with the association from West Germany Government in 1971 which led to establishment of Expressway Authority of Thailand under Clause 39 of the Announcement of the Revolutionary Council Decree 290 dated 27 November 1972 (B.E.2515) to responsible for planning and construction of expressway and mass rapid transit projects.
In 1979, the master plan compiled by Japanese advisers would have consisted of the First Stage Urban Mass Transit Lines such as the first line known as the Rama IV line, a 25-km route between Phrakhanong and Mo Chit, while the second line, the Sathon line, a 20-km route would connect Wongwian Yai and Lad Phrao, and the third line, the Memorial Line, a 16-km route that connects Dao Khanong and Makkasan, and the expected numbers of passengers were expected to be 200,000 passengers a day in 1990. The rolling stock would have utilized six heavy rail cars running at 15 minutes per train for non-rush hour and four minutes during rush hour, compared with current trains running at 6–8 minutes per train during non-rush hour and 3–5 minutes per train during rush hour, using three heavy rail cars. The project was meant to have a cost of $1100 million.
The finalised version of the project consisted of three light rail transit lines which are Sathorn Line, Rama IV Line, and Saphan Phut Line, with the depot located in Huai Khwang district (current location of Phra Ram 9 depot of MRT Blue Line). The project was expected to begin in 1981 and be completed in 1986. However, due to the 1979 oil crisis, Lavalin Skytrain project was shelved as the estimated costs were doubled.

Why this record matters
The subject matters to the general reference register because the source frames it as master plan for the creation of urban rail transit systems in Bangkok, Thailand. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 12, 2026. The linked authority identifier is Q387067. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1971, 1972, 1979 and 1990.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
