Pink Line (Bangkok)
The MRT Pink Line (Thai: รถไฟฟ้ามหานคร สายสีชมพู) is an elevated monorail line of the MRT in Bangkok and Nonthaburi Province, Thailand. The monorail line is 34.5 kilometres (21.4 mi) long and has 30 stations. It runs in the northern part of the Bangkok Metropolitan Area from Nonthaburi Civic Center in Pak Kret district, Nonthaburi along the major east–west transport corridor of Highway 304 (Chaeng Wattana and Ram Inthra roads) to terminate at Min Buri in Min Buri district in east Bangkok. It opened for free public trial operation on 21 November 2023 with then Prime Minister Srettha Thavisin taking the inaugural ride.
The line is designed to link the northern areas of Bangkok and Nonthaburi by connecting with three existing and three future mass transit lines. At Nonthaburi Civic Center the line interchanges with the MRT Purple Line and the proposed MRT Brown Line. The line also interchanges with the SRT Dark Red Line, the BTS Sukhumvit Line and the planned BMA Grey Line. At the Min Buri terminus, the line interchanges with the MRT Orange Line.
Construction of the Pink Line began in December 2017. In October 2020, the BSR consortium stated that they aimed to open the first section of the Pink Line by October 2021, with services initially operating from Min Buri (PK30) to Government Complex (PK12). The complete line was originally set to be fully open by June 2022. However, the outbreak of COVID-19 in Bangkok and changes to station locations delayed the opening date. On 24 September 2021, the MRTA Board granted a 290-day extension to the construction contract period. In November 2021, the MRTA Board approved a new phased opening of the line starting from August 2022. On 9 December 2021, daily testing conducted at a maximum speed of 25 km/h (16 mph) began on a short 4 km (2.5 mi) section of the line between the depot at Min Buri and Bang Chan station. After a period of 3 months, testing was conducted at higher speeds and along a longer section of track.
In April 2022, the acting Director-General of the Department of Rail Transport stated that the line would not begin full testing until September 2022 and that the first stage would not open until late December 2022. In May 2023, a further 345-day extension was announced by the MRTA, delaying the start of trial operations for the initial section and later the final opening of the full line to June 2024. However, after the opening of the MRT Yellow line the BSR announced that the first section of the line would open in November 2023.
The line opened for free public trial operation on 21 November 2023 and officially launched on 18 December 2023. Revenue service was initially scheduled to begin on 3 January 2024, but an incident involving conductor rails resulted in a delay to 7 January, with a 15 percent discount for travels between Royal Irrigation Department and Min Buri, and the first four stations will be free of charge, running only in one direction on rails unaffected by the incident as a shuttle service, while the affected rails are being repaired.
On 20 May 2025, Muang Thong Thani Line, a branch line from the main Pink Line, began free trial operations between Muang Thong Thani and Lake Muang Thong Thani stations. Full commercial operation will begin on 17 June 2025.
The line begins at Nonthaburi Civic Center near Khae Rai Junction, Nonthaburi Province, in the northwest of Greater Bangkok. The line then heads north along Tiwanon Road to Pak Kret Intersection, Pak Kret District, before turning east to run along Chaeng Watthana road. It interchanges with the SRT Dark Red Line at Lak Si Station and passes over Vibhavadi Rangsit Road running east through the Ram Intra intersection and the Lak Si Monument in Bang Khen District, where it crosses under the BTS Sukhumvit Line and interchanges with Wat Phra Sri Mahathat. The line then continues farther east along Ram Inthra Road to the northeast of Bangkok before terminating at Min Buri station where it will interchange with the MRT Orange Line once the line open.
The Pink Line was first proposed in 2005 by the Office of Transport and Traffic Policy and Planning as a heavy rail underground line. It was changed to a monorail line in 2008 to reduce construction costs. The director-general of the Office of Transport and Traffic Policy and Planning had previously stated in an interview that the Pink Line was considered a priority scheme to be completed by 2017–18, as it ran past the then recently opened Bangkok Government Complex. A review was undertaken in early 2012 to reconsider the heavy rail option, but cost restraints prevailed and the Office decided to continue with the monorail plan. The review of the line did result, however, in the addition of 6 new stations. The environmental impact assessment for the Pink Line was finalized in late 2012. In October 2012, members of the new government requested to extend the planned line east by 3.4 km (2.1 mi) beyond the Min Buri terminus to Nong Chok. However, this extension of the line was not approved. The expected cost of the line in 2012 with the additional 6 extra stations was 55 billion baht.
