The Yellow Line is an elevated mass rapid transit line currently under construction in Bangkok and Samut Prakan Province, Thailand.

The 30.4-kilometre-long (18.9 mi) line will have 23 stations (plus two new proposed stations awaiting approval) and cost 55 billion baht. It was originally proposed to be an underground and elevated heavy rail line. However, it was decided in 2012 to build an elevated monorail line in order to reduce construction costs.

Preliminary site works began in late 2017 with major construction of the monorail due to begin in the 2nd quarter of 2018. The line is due to be operational in 2022.


The line starts at the intersection of Ratachadapisek and Lat Phrao roads where it interchanges with the MRT Blue Line at Lat Phrao station. The line then heads east along Lat Phrao road to Bangkapi junction where it will interchange with the Orange Line Lam Sali station, before heading south along Srinagarindra Road to Hua Mark where it will interchange with the Airport Rail Link Hua Mak station.

From Hua Mark the route continues south along Srinagarindra Road past Bangna-Trat Road all the way to Thepha Rak Road in Samut Prakan Province, then heading west along Thepha Rak Road before terminating at Samrong of the BTS Sukhumvit Line.[1]

The line will be built from Ratchada (Y1) to Samrong (Y23), with construction planned to take four years to complete. The Yellow Line depot will be located at Hua Mark adjacent to Y11 station. [2]


In December 2011, the MRTA was instructed by the MOT to divide the Yellow Line into two phases for tender and construction purposes and to control land appropriation costs.[3] In June 2012, the MRTA contracted consultants to undertake detailed designs of the Yellow Line. In February 2013, OTTP stated that the tender for the Yellow Line should be ready by late 2013 for tender in early 2014.[4] By August 2013, this timeline had changed to a mid-2014 tender date.[5]

However, similar to the MRT Pink Line, delays in finalising the technical requirements of the tender in relation to the selection of monorail rolling stock which determines the type of track to be constructed resulted in further delays. The subsequent political turmoil of late 2013 and early 2014 caused even more delay. Thereafter, the coup of May 2014 resulted in a new military administration and the tender being deferred for 2014. The MRTA tender was subsequently not released until mid-2016. In early December 2016, BSR Joint Venture (comprising BTS Group Holdings which owns 75%, Sino-Thai Engineering and Construction - STEC, and Ratchaburi Electricity Generation Holding - RATCH), won the bid for the line. The BSR also won the bid for the Pink Line. [6]

On June 16 2017, a contract was signed for the line with the Mass Rapid Transit Authority of Thailand and a consortium including BTS Group Holdings, Sino-Thai Engineering and Construction, and Ratchaburi Electricity Generation Holding. BSR has also established Eastern Bangkok Monorail Company Limited to operate the monorail. A proposed 2 station extension of the route north from the current Ratchada terminus to link to Sukhumvit Line Extension at Ratchayothin station is awaiting approval from the government.[7]

Rolling stock[edit]

BSR has selected Bombardier INNOVIA 300 monorail rolling stock for the Yellow line.[8] The BSR has announced that they will purchase 28, 4 car sets to operate the Yellow line.[9]
