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] As of 2023, the plan was for a 8.3km line with 13 stops, linking to the Don Mueang–Suvarnabhumi–U-Tapao high-speed railway.[6]

It is projected that the first of three lines could break ground in 2021, and the system could be operational by roughly 2027.[7]

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.[8]

Nakhon Ratchasima Municipality has a plan to build five elevated bus rapid transit (or Skybus) lines with the name Korat Rapid Transit.[9] As of 2018, there has been no progress.

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.[10] It is hoped that construction will begin in 2019.

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.[12] The project will be modelled on the Sydney tramway network.[2]
