The '''MRT Yellow Line''' ({{langx|th|รถไฟฟ้ามหานคร สายสีเหลือง}}) or '''MRT Nakkhara Phiphat Line''' ({{langx|th|รถไฟฟ้ามหานคร สายนัคราพิพัฒน์}}) is an elevated [[monorail]] line in [[Bangkok]] and [[Samut Prakan Province]], [[Thailand]]. It is the third line of the [[MRT (Bangkok)|MRT]] rapid transit system. The {{Cvt|28.62|km}} line has 23 stations and cost 55 billion baht.<ref>{{Cite web|url=https://mrta-yellowline.com/wp/en/|title = MRTA Yellow Line project |access-date= |url-status=live |archive-url=https://web.archive.org/web/20230911073032/https://mrta-yellowline.com/wp/en/ |archive-date=2023-09-11 }}</ref> The line was originally proposed in 2005 by the Office of Transport and Traffic Policy and Planning to be a heavy rail underground line along Lat Phrao road which was then elevated from Lam Sali Intersection to Samrong. However, it was decided in 2012 to build an elevated monorail line for the whole length in order to reduce construction costs.
The Yellow Line provides mass transit along the heavily congested [[Lat Phrao Road]] and [[Srinagarindra Road]] corridors. The line links 6 other lines; the [[MRT Blue Line]], interchange with the [[MRT Orange Line]] (which is under construction), the planned [[MRT Grey Line]] and [[MRT Brown Line]], the [[Airport Rail Link (Bangkok)]] and finally the [[Sukhumvit Line|BTS Sukhumvit Line]]. As such, it is an important cross city link in the middle north-eastern and eastern areas of Bangkok.
Preliminary site works began in late 2017 with major construction work starting from March 2018. In October 2020, the BSR stated that they plan to open the first section of the Yellow Line by October 2021 with initial operations running from [[Samrong station|Samrong]] to [[Si Iam MRT station|Si Iam]].<ref>{{cite news |title=เปิดไทม์ไลน์-ค่าตั๋ว รถไฟฟ้าไร้คนขับ "สายสีชมพู-เหลือง"|url=https://www.prachachat.net/property/news-530591 |newspaper=Prachachat |date=1 October 2020}}</ref> The line was then planned to fully open in July 2022.<ref name=tangled>{{cite news |last1=Theparat |first1=Chatrudee |title=Tangled lines |newspaper=Bangkok Post |url=https://www.bangkokpost.com/property/2011035/tangled-lines |access-date=31 October 2020 |agency=Bangkok Post |date=30 October 2020}}</ref> However, due to COVID-19 outbreaks in Bangkok delaying construction with sites closed, the BSR stated that the first section of the line would not open until July 2022.<ref name="mgronline.com">{{cite news |title=วิ่งทดสอบฉลุย! โมโนเรล 'สายสีเหลือง' ทำความเร็ว 80 กม./ชม. พร้อมบริการกลางปี 65 |url=https://mgronline.com/business/detail/9640000118855|newspaper=Manager Online |date=30 November 2021}}</ref> On 29 November 2021, daily testing began on a {{Cvt|6|km}} section of the line between the depot at Si Iam and [[Srinagarindra 38 MRT station|Srinagarindra 38 station]].

In mid-April 2022, the director of EBM/BSR, Mr Surapong Laoha-Unya, stated that further labour & installation delays would mean that the line would now not open until September 2022.<ref>{{cite news |title=วันสงกรานต์..สาดความสดใส โมโนเรลชมพู&เหลืองได้นั่งส.ค.น. |url=https://www.dailynews.co.th/articles/953956/|newspaper=Dailynews |date=13 April 2022}}</ref> Construction had progressed to 99.02% as of the end of April 2023.{{citation needed|date=August 2025}}

Following two incidents of operational failure in January and March 2024, His Majesty the King of Thailand bestowed an auspicious name upon Bangkok's Yellow Line monorail on 30 May 2024. The line has been officially renamed '''"Nakkhara Phiphat"''' ''([[Pali]]: Nagara Vivaḍḍhana)'', meaning "prosperity of the city," by royal command.<ref>{{Cite web |date=30 May 2024 |title=His Majesty renames Yellow Line as 'Nakkhara Phiphat' |url=https://www.nationthailand.com/news/general/40038428 }}</ref>
==Route alignment== The line starts at the intersection of Ratchadaphisek and Lat Phrao roads where it interchanges with the [[MRT Blue Line]] at [[Lat Phrao MRT Station|Lat Phrao station]]. The line then heads east along Lat Phrao road to Bang Kapi intersection and south to Lam Sali station to interchange with the [[MRT Orange Line]] and the future [[MRT Brown Line]]. The line continues further south along Srinagarindra Road to Hua Mak where it interchanges with the [[Airport Rail Link (Bangkok)|Airport Rail Link]] at Hua Mak station.
From Hua Mak, the route continues south along Srinagarindra Road past the [[Debaratna Road|Debaratna (Bang Na-Trat) Road]] all the way to Thepharak Road in [[Samut Prakan Province]], then heading west along Thepharak Road where it terminates at Samrong and interchanges with [[Samrong station|Samrong]] of the [[Sukhumvit Line|BTS Sukhumvit Line]].<ref>{{Cite news|url=https://www.mrta.co.th/pinkline/inno_02.html|title=MRT Yellow line Route|language=en|archive-date=2017-10-24|access-date=2022-04-19|archive-url=https://web.archive.org/web/20171024061824/http://www.mrta.co.th/pinkline/inno_02.html|url-status=dead}}</ref>
The line stretches from Lat Phrao (YL1) to Samrong (YL23) and the depot is located at Debaratana Road adjacent to Si Iam station (YL17).
==History== The Yellow line was first proposed in the mid-1990s as a monorail line by Japanese consultants with little or no progress for 10 years. In 2004, the [[Office of Transport and Traffic Policy and Planning]] (OTP) reworked the proposal as a heavy rail line with underground and elevated sections as part of the 10 line metro plan which was taken to the February 2005 election. In 2009, it was suggested to change the line to an elevated monorail line as a cost saving measure. 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 reduce land appropriation costs.<ref>{{cite web|url=http://www.thanonline.com/index.php?option=com_content&view=article&id=99466:2-&catid=128:-real-estate-&Itemid=478|title=ฐานเศรษฐกิจ - Connecting Opportunity|access-date=27 August 2016}}</ref> In June 2012, the MRTA contracted consultants to undertake detailed designs of the line. In February 2013, OTP stated that the tender for the Yellow Line should be ready by late 2013 for tender in early 2014.<ref>{{cite web|url=http://www.thaipost.net/news/110213/69374 |title=สนข.เร่งสร้างรถไฟฟ้า ฟุ้งปี56ได้ใช้ตั๋วร่วมแน่ | ไทยโพสต์ |access-date=2014-06-27 |url-status=dead |archive-url=https://web.archive.org/web/20131216182702/http://www.thaipost.net/news/110213/69374 |archive-date=2013-12-16 }}</ref> By August 2013, this timeline had changed to a mid 2014 tender date.<ref>{{Cite web|url=http://www.manager.co.th/iBizChannel/ViewNews.aspx?NewsID=9560000105880|title=ผู้จัดการออนไลน์ รวดเร็ว สด ทุกเหตุการณ์|access-date=2013-12-16|archive-date=2013-12-16|archive-url=https://web.archive.org/web/20131216190703/http://www.manager.co.th/iBizChannel/ViewNews.aspx?NewsID=9560000105880|url-status=dead}}</ref>
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 delays. Thereafter, a coup in May 2014 resulted in a new military administration and the tender being deferred while a review of all mass transit projects was undertaken for a period of 18 months. The MRTA was instructed by the junta government to change to a PPP tender process which was subsequently not released until mid-2016. In early December 2016, The BSR consortium consisting of [[BTS Group Holdings]] (75% majority stake) with Sino-Thai Engineering and Construction (STEC), and Ratchaburi Electricity Generation Holding (RATCH), won the bid to construct and operate the Yellow Line. The BSR also won the bid to build and operate the [[MRT Pink Line]].<ref>{{cite news |title=BSR Joint venture wins rights for Bangkok's Yellow, Pink line MRTA construction|url=http://www.bangkokpost.com/archive/joint-venture-wins-rights-for-yellow-pink-line-construction/1153213 |newspaper=Bangkok Post |date=7 December 2016}}</ref>
On June 16, 2017, the contract was signed for the project between the [[Mass Rapid Transit Authority of Thailand]] and BSR consortium. The BSR established the Eastern Bangkok Monorail Company Limited (EBM) to operate the line. A proposed 2 station extension of the route north from the Lat Phrao terminus to link to the BTS [[Sukhumvit Line]] at Ratchayothin station has also been proposed by the BSR Joint Venture.<ref name="The Nation">{{Cite news|url=https://www.nationthailand.com/news/business/EconomyAndTourism/30318283|title=Junta to call bids for most infra projects - The Nation|work=The Nation|access-date=2017-06-17|language=en}}</ref> However, this extension is opposed by the [[MRT Blue Line]] operator [[Bangkok Expressway and Metro Public Company Limited|BEM]] due to concerns regarding loss of revenue.<ref name="ReferenceA">Author meeting with MRTA planning division on 7 August 2019 at MTRA Headquarters</ref>
Construction of the Yellow Line began in March 2018.<ref>{{cite news |title=Construction of monorail lines gets ceremonial launch |url=https://www.bangkokpost.com/news/transport/1529266/construction-of-monorail-lines-gets-ceremonial-launch. |newspaper=Bangkok Post |date=27 August 2018}}</ref>
The public trial run started on 3 June 2023, between Hua Mak and Samrong. The Phawana-Si Kritha section opened on 12 June,<ref name=":2" /> while Lat Phrao station opened on 19 June.<ref name=":1" /><ref name=":3" />
As of June 2024, passengers are required to change train due to technical difficulties, sections of station runs in different frequency. Latphrao to Huamak runs every 5 minutes, Huamak to Sri Iam runs every 25 minutes and from Sri Iam to the terminus Samrong every 10 minutes. Yellow maintenance carts can be seen along the line from Huamak to Samrong.
===Northern extension=== A proposed 2-station extension of the route north from the current Ratchada terminus to link to the BTS [[Sukhumvit Line]] Extension at Ratchayothin station has also been proposed by the BSR Joint Venture.<ref name="The Nation" /> However, this extension is opposed by the [[MRT Blue Line]] operator [[Bangkok Expressway and Metro Public Company Limited|BEM]],<ref name="ReferenceA" /> estimating about 988 million baht loss on the extension's first year of service and 2.7 billion baht throughout the 30-year concession period.<ref name=":0">{{Cite web |date=2021-03-22 |title=BEMร้องขอค่าชดเชย ชี้รายได้หด/หลัง'สายสีเหลือง'วิ่ง |url=https://www.naewna.com/business/560756 |access-date=2021-11-01 |website=www.naewna.com |language=th}}</ref>

===Southern extension=== A future extension from [[Samrong station]] across the [[Chao Phraya River]] to link with the [[MRT Purple Line]] at Rat Burana was canvassed by the OTP in the early 2010s. However, the current location and design of Samrong station excludes any further extension of the line west of Sukhumvit Road.

===Guideway beams=== [[File:Yellow Line at Lat Phrao Station 02.jpg|thumb|Elevated guideway beams at [[Lat Phrao MRT Station|Lat Phrao Station]]]] The Bombardier Innovia Monorail 300 operates on a narrow, elevated guideway beam. Pre-cast, post-tensioned guideway beams are constructed at an off-site location and later installed on the system. The guideway beams are {{Cvt|690|mm}} wide.<ref name="TPInnovia300" /> The Innovia Monorail 300 was designed to navigate curves as tight as {{Cvt|46|m}} and a maximum grade of 6%. Monorail switches are either beam replacement or multi-position pivot switches.<ref>{{cite web |title=INNOVIA Monorail 300 System: a mass transport solution for the megacity of São Paulo |url=http://www.cg-la.com/documents/LALF11/presentations/6.4.13UMTBombardier.pdf |url-status=dead |archive-url=https://web.archive.org/web/20160304030236/http://www.cg-la.com/documents/LALF11/presentations/6.4.13UMTBombardier.pdf |archive-date=2016-03-04 |access-date=2020-08-15 |website=CG/LA Infrastructure, Inc}}</ref> The system has evacuation walkways down the entire length of the guideway beam.
