Bangkok Metropolitan Region

The BTS Skytrain

Map of Bangkok urban transit systems

Bangkok Metropolitan Region is, as of 2018^[update], served by three rapid transit rail systems. The BTS Skytrain consists of two elevated lines, the Sukhumvit Line and the Silom Line. The underground Metropolitan Rapid Transit (MRT) also consists of two lines, the Blue Line and Purple Line. Finally, the elevated Airport Rail Link (ARL) links to Suvarnabhumi Airport. Although proposals for the development of rapid transit in Bangkok had been made since 1975,^[1] leading to plans for the failed Lavalin Skytrain, it was only in 1999 that the BTS finally began operation.

Central

Phitsanulok

In Phitsanulok, there is a plan to build a tramway system which has several lines. The project will be modelled on the Sydney tramway network.^[2]

Eastern

Pattaya

Pattaya City had a plan to build a monorail line consisting of ten stations. As of 2018, there has been no progress.^[3] In 2020 a new plan called for a 9km, 11 station monorail. A 50 million baht feasibility project would be commissioned first. ^[4] The monorail could open by 2026 with additional lines added in the 2030s.^[5]

Northern

Chiang Mai

Chiang Mai Municipality has one existing monorail system, Chiang Mai Zoo Monorail, used for excursions within the zoo. Plans for an electric rail system have been discussed for years. In 2018, the plans seem to have gained traction. The Mass Rapid Transit Authority of Thailand (MRTA) announced that the bidding process for a tram network in Chiang Mai could begin in 2020.^[6] The 35 km tramway, both above and below ground, is estimated to cost 86 billion baht. It is projected that the first of three lines could break ground in 2021, and the system could be operational by roughly 2027.^[6]

Northeastern

Khon Kaen

In Khon Kaen, there is a plan to build a Light Rail with several lines. In 2016, a 26 kilometer-long light rail line was proposed. The light rail line, which is to be funded by local government and businesses instead of the central government, hopes to begin construction in 2019.^[7]

Nakhon Ratchasima

Nakhon Ratchasima Municipality has a plan to build five elevated bus rapid transit (or Skybus) lines with the name Korat Rapid Transit.^[8] As of 2018, there has been no progress. Later, there is a plan to build a tramway system of several lines.^[2] The project will be modelled on the Sydney tramway network.^[2]

Southern

Hat Yai and Songkhla

Hat Yai monorail is a planned 12.54 kilometer-long elevated monorail consisted of 12 stations. As of 2016, the line is being studied by a university and the government. The design of the stations has been completed. The project will cost approximately 15,799 million baht to construct.^[9] It is hoped that construction will begin in 2019.

State Railway of Thailand (SRT) has a plan to build commuter rail linking Hat Yai and Songkhla by reusing a defunct railway line that closed in 1978.^[10]

Phuket Island

The Mass Rapid Transit Authority of Thailand (MRTA) announced in 2018 that bidding to construct a 60 kilometre-long, 23 station tram network in Phuket will commence in 2020. The 39 billion baht tram is part of the government's Private-Public-Partnership (PPP) plan which ensures it will be fast-tracked. The planned route stretches from Takua Thung District in Phang Nga Province to Chalong in Phuket. Phase one will connect Phuket International Airport with Chalong, about 40 kilometres. It will take three years to complete.^[11] The project will be modelled on the Sydney tramway network.^[2]
