TheMass Rapid Transit Master Plan in Bangkok Metropolitan Region, orM-Map, is the latest version in a series of Thai government plans for the development of anurban rail transit network serving theGreater Bangkok area. It was drafted under the care of theOffice of Transport and Traffic Policy and Planning (OTP) of theMinistry of Transport.
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 ofExpressway Authority of Thailand underClause 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 betweenPhrakhanong and Mo Chit, while the second line, the Sathon line, a 20-km route would connectWongwian Yai andLad Phrao, and the third line, the Memorial Line, a 16-km route that connectsDao Khanong andMakkasan, and the expected numbers of passengers were expected to be 200,000 passengers a day in 1990.[2] 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.[2] The project was meant to have a cost of $1100 million.[3]
The finalised version of the project consisted of threelight rail transit lines which are Sathorn Line, Rama IV Line, and Saphan Phut Line, with the depot located inHuai Khwang district (current location of Phra Ram 9 depot ofMRT Blue Line). The project was expected to begin in 1981 and be completed in 1986. However, due to the1979 oil crisis, Lavalin Skytrain project was shelved as the estimated costs were doubled.
The project was revised under the government ofGeneral Prem Tinsulanonda in 1984 and entered the bidding process with three participating companies being Asia-Euro Consortium (comprisingAEG,Siemens,MAN, andAteliers de Constructions Electriques de Charleroi),[4]SNC-Lavalin, and Franco-Japanese Consortium. The project was awarded toSNC-Lavalin, and the contracts for a 30-year operating concession and construction were signed in May 1990 atQueen Sirikit National Convention Centre.
However, after two years of construction, In June 1992, The project was terminated by the government ofAnand Panyarachun . The government stated that SNC-Lavalin failed to sign a shareholders agreement by a specified and the Thai government refused requests for overseas loan and investment guarantees.[5] Outside of Thailand, numerous international media sources suggested politics played in its demise.
Today, There are two remainings from the construction of Lavalin Skytrain project: the abandoned viaduct in the middle ofPhra Pok Klao Bridge (now converted intoChao Phraya Skypark),[6] and a reserved space in the middle ofSathorn Bridge (currently used bySilom Line).
The concept of developing a master plan began in 1972 when the Thai government sought cooperation from theGerman government to jointly develop a mass transit network. Subsequently, the Cabinet passed a resolution approving the continuous study, promotion, and support for the creation of the master plan starting from 1994. The sequences of the master plan are as follows:
The first version of the plan, endorsed by the Cabinet on 27 September 1994 and to be implemented from 1995 to 2011, consisted of an extension of 135 kilometres (84 mi) to the three systems already in progress ( MRT , BTS , BTS and theBERTS), which would have had a combined length of 135 kilometres (84 mi)[7] The plan was divided into two phases as follows:
Later, in 1996, the Office of Transport and Traffic Policy and Planning (OTP) revised this master plan and renamed it the Comprehensive Transport Master Plan (CTMP), which included an additional 178.9 kilometres (111.2 mi) of routes. This revised master plan includedmonorail andlight rapid transit lines to enhance Bangkok into a rail transportation metropolis. The plan consisted of 11 railway projects with a combined length of 206 kilometres (128 mi), as follows;

Following the1997 Asian Financial Crisis and the cancellation of theBERTS, in 1998, the Cabinet passed a resolution stating that the Office of Transport and Traffic Policy and Planning (OTP) should conduct a feasibility study for a new master plan to replace the CTMP due to the development not progressing as planned and because Thailand was in the process of recovering from the economic crisis. The main objective of this new master plan is to emphasise the distribution of urban growth from the city centre to suburban areas, promoting more decentralised urban development along major roads.
The new master plan has been adapted with several projects modifying routes from the CTMP, emphasising distribution to various areas as follows:
This master plan is a conversion of the URMAP master plan into practical implementation based on government policies, which stipulate that projects in the previous master plan must be completed within 6 years (2004 – 2009). This period coincides with the recovery of the economy from the crisis in 1997. The master plan outlines a mass transit network in areas anticipated to experience continuous and increasing land use in the future. It specifies the construction of one railway station every 2 kilometres in the city areas and every 1 to 1.5 kilometres in suburban areas, aiming for the rapid transit project to be a guiding initiative for future urban development.
This master plan consists of 7 rapid transit lines with an additional 291.2 kilometres (180.9 mi) added to the existing 43.7 kilometres (27.2 mi). These lines are categorised into three groups as follows;
In 2006, the Cabinet revised the previous BMT master plan with the aim of expanding coverage to more areas in Bangkok. Three routes were added to this master plan, as follows:
In 2008, the government revised the master plan for the rapid transit network once again, focusing on urban expansion and increasing transit routes in suburban areas, taking into account the growing urbanisation projected for the future. This revision resulted in a total of 9 lines with a combined length of 311 kilometres (193 mi). The revised routes are as follows:
ARL has been added.In 2009, the government revised the M-Map, this time considering urban expansion and the distribution of development to suburban areas, guided by the rapid transit projects. This revised M-Map includes the study of a total of 12 transit lines, with a combined length of 509 kilometres (316 mi) , consisting of 8 main lines and 4 feeder lines, as follows:[8]
| Line Name | Route | Notes |
|---|---|---|
| Main Line | ||
| Dark Red Line | Thammasart University (Rangsit Campus) - Mahachai | |
| Light Red Line | Salaya - Hua Mak | Extended fromTaling Chan toSalaya. |
| Taling Chan - Makkasan | ||
| Airport Rail Link | Don Mueang - Suvarnabhumi Airport | |
| Light Green Line | Eastern Ring Road-Lam Luk Ka - Bang Pu | |
| Dark Green Line | Yot Se - Bang Wa | |
| Blue Line | Phutthamonthon - Hua Lamphong - Bang Sue - Tha Phra | |
| Purple Line | Bang Yai - Rat Burana | |
| Orange Line | Taling Chan - Min Buri | The line was altered fromBang Bamru toTaling Chan, passing throughPratunam, and theBrown Line (Bang Kapi - Min Buri) has been merged. |
| Feeder Line | ||
| Pink Line | Khae Rai - Min Buri | |
| Yellow Line | Lat Phrao - Samrong | The line was downgraded from the Outer Circle Line, with the northwestern and southwestern sections being removed from the master plan. |
| Grey Line | Vatcharaphol - Rama IX Bridge | This line was formed by the Wacharaphol to Pracha Uthit Line from the CTMP master plan to terminate atRama IX Bridge. |
| Light Blue Line | Din Daeng - Sathorn | This line was designed to support the opening of the new Bangkok Metropolitan Administration building and to enhance connectivity in theSathorn district. |
This master plan has been implemented for the development of actual projects since 2011. Currently, over 70% of the plan has been completed. However, with the unsuitability of certain routes, the master plan has been revised. This revision includes cancellations, modifications, and suspensions of 5 routes as follows
ARL : Became the part ofDon Mueang–Suvarnabhumi–U-Tapao high-speed railway.As a result, the rapid transit network in Bangkok and its surrounding areas now consists of 10 lines.
To accommodate the expansion of the city into the suburban areas, in March 2017, the Cabinet assigned the Ministry of Transport and the Office of Transport and Traffic Policy and Planning (OTP) to study an additional 10 transit lines. These lines were to be included in the M-Map Phase 2. The study was to be conducted in collaboration with theJapan International Cooperation Agency (JICA)[9][10] to plan and support the necessary budget for investment, should there be a need to secure foreign loans for the project.
The second phase of the M-Map 2 focuses on developing feeder lines to support urban expansion and feed passengers into Bangkok's main transit routes, which include the BTS , BTS , MRT , MRT , SRT , SRT , and ARL . Initially, the Office of Transport and Traffic Policy and Planning (OTP) considered incorporating routes that had not yet been implemented, were under study, were outside the master plan, or had been canceled from the previous master plan. Four pilot routes were identified. Additionally, theMass Rapid Transit Authority of Thailand (MRTA) proposed 8 new lines to be included in the master plan, resulting in a total of 11 initial routes.
Subsequently, the OTP, in collaboration with theJapan International Cooperation Agency (JICA), revealed the details of the draft master plan for the M-Map 2, which was approved byJICA. This draft included 5 new lines totaling 131 kilometres (81 mi), both as extensions of existing lines and as new lines. However, due to changing circumstances, the Department of Rail Transport (the current status of the OTP) reconsidered the entire M-Map 2. They proposed a new long-term plan (Project Long List) consisting of 29 lines, which will be submitted to the Cabinet for approval as the actual master plan in the future.
On July 25, 2023, the Department of Rail Transport officially announced the draft of the M-Map 2. This new master plan will be submitted to the Cabinet for official approval in 2024, with the goal of expediting the commencement of all projects within 20 years, by 2042. The master plan is divided into three main categories as follows[11]
| Line Name | Route | Notes |
|---|---|---|
| Group 1: Extensions for the existing line | ||
| Light Green Line | Khu Khot to Eastern Ring Road-Lam Luk Ka | Both routes are from the previous master plan that was not completed.MRTA has temporarily halted these plans until there is clarity on passenger guarantees. |
| Kheha to Tamru | ||
| Dark Green Line | National Stadium to Yot Se | |
| Bang Wa to Bang Rak Noi Tha It | This is a new route proposed by JICA for theBang Wa toLam Sali Line. However, sinceMRTA has developed theNonthaburi Civic Center toYaek Lam Sali section as theBrown Line, the Department of Rail Transport has considered changing the missing section betweenBang Wa andNonthaburi Civic Center into an extension of theSilom Line, terminating atBang Rak Noi Tha It instead. | |
| Blue Line | Lak Song to Phutthamonthon Sai 4 | The route is from the previous master plan that was not completed.MRTA has temporarily halted these plans until there is clarity on passenger guarantees. |
| Dark Red Line | Rangsit to Thammasart University (Rangsit Campus) | These routes have been approved but are currently not yet implemented. |
| Bang Sue to Hua Lamphong | ||
| Wongwian Yai to Mahachai | ||
| Hua Lamphong to Mahachai | ||
| Light Red Line | Taling Chan to Salaya | |
| Taling Chan to Siriraj | ||
| Airport Rail Link | Lat Krabang to Chachoengsao | The proposed route by the Department of Rail Transport, which cancels theLight Red Line from Bang Sue to Hua Mak to Chachoengsao. Instead, it will utilize part of the infrastructure from theDon Mueang–Suvarnabhumi–U-Tapao high-speed railway to add new stations for the Airport Rail Link City Line, expanding travel areas and replacing the entire eastern segment of theLight Red Line |
| Gold Line | Prachadhipok | BMA has temporarily halted these plans until there is clarity on passenger guarantees. |
| Group 2: New proposed line | ||
| Brown Line | Nonthaburi Civic Centre to Yaek Lam Sali | |
| Grey Line | Vatcharaphol to Thong Lo | The proposed route by theBMA, which separates the original Grey Line into distinct sections. The northern section largely follows the original plan, and the Department of Rail Transport has extended the line further to Lam Luk Ka Road |
| Vatcharaphol to Khlong Si | ||
| Phra Khanong to Rama III | The proposed route by theBMA will replace the existingBangkok BRT. | |
| Rama III to Tha Phra | ||
| Light Blue Line | Sathorn to Din Daeng | This route has been revived after has been removed from the original M-Map. |
| Silver Line | Bang Na to Suvarnabhumi Airport | The proposed route by theBMA, which separates the extension of theLight Green Line from Udom Suk to Suvarnabhumi Airport for independent development |
| Group 3: Feeder Line | ||
| Lat Phrao to Nonthaburi Pier | Most of these routes focus on feeding passengers into the main transit system and may be proposed to operate as regular buses, bus rapid transit, trams, or may be considered as extensions of connectable routes. | |
