The MRT Brown Line is a 22 km rapid transit line under preliminary study in Bangkok, Thailand. The line is proposed to run from Khae Rai, Nonthaburi to Bueng Kum, Minburi with 21 stations as a monorail.

The line was first proposed as the Gold Line by the Pheu Thai party for the Bangkok Governors election held in March 2013. This was in response to objections by Kasetsart University and as an alternative to a long-proposed elevated Expressway extension. [1] However, the Pheu Thai candidate did not win the election and the Gold Line proposal was dropped with the then Deputy Minister of Transport stating that land appropriation costs were too high.[2]

Subsequently, OTP reworked the Gold Line proposal into a new Brown Line monorail proposal following a comparable route. The route was under preliminary study by OTP from June 2013, but did not progress much before the May 2014 coup and change of government.[3] Subsequently, the route was finalised by OTP and public hearing into the project were held during 2017. In mid 2017, the MOT announced that a final feasibility study would be completed over 14 months by mid 2018.

Note: This line is not to be confused with the original 2004 13 km Brown Line proposal from Bangkapi to Min Buri. This was subsequently merged in 2009 into an extended MRT Orange Line which is currently under construction.


The Brown Line will start at Nonthaburi Civic Center and continue to Khae Rai and along Ngam Wong Wan road to Vihavadi-Rangsit road (interchange with SRT Dark Red Line) and continue east to Kaset. The Civic Center line would interchange with MRT Purple Line & MRT Pink Lines. Kaset would interchange with BTS Sukhumvit Line.

The line heads east along Prasote Manukit road (AKA Kaset-Nawamin rd) past Chalong Rat Expressway (interchanging with the proposed Grey Line) to Nawamin Rd. It continues south along Nawamin Road and cuts through directly southeast from Nawamin soi 30 junction to Seri Thai rd soi 35 junction. The line extends further southeast where it terminates at Ramkhamhaeng rd (soi 129/1 junction) to interchange with MRT Orange Line.


In August 2013, the MRTA approved the line in principle with a goal to complete design by 2016 with an expected 3-year construction period.[4] However, the line was delayed while a long planned expressway along much of the same route was prioritized. [5]. Public hearings on the Brown line where held in 2017. The MOT announced that a 14-month feasibility study into the line would be completed by 2018. [6] The feasibility study is being undertaken during the same period where design for the N2 expressway (which runs along Kaset-Namawin rd) is being finalised without catering for the Brown Line. Work is expected to commence on the expressway in late 2018. [7]


The 22 km Brown line will have 21 stations (plus 2 potential future stations):
