The monorail will be 34.5 km long with 30 stations. It will run in the northern part of the city from east Bangkok in Minburi , Bangkok along Ram Inthra Road to west Bangkok (Pak Kret District, Nonthaburi Province), Chaeng Watthana Road and Tiwanon Road ending at the Nonthaburi Civic Center. At the terminus there will be an interchange with MRT Purple Line and the proposed MRT Brown Line which is currently under evaluation. A short spur line to Impact, Muang Thong Thani from Si Rat station has also been proposed.
The line will also transfer with the SRT Dark Red Line which is under construction, the planned BTS Sukhumvit Line extension to Khu Khot (under construction), the planned BMA Grey Line in the future and interchange with the MRT Orange Line which is under construction. As such, it will be an important cross city link in the northern area of Bangkok & Nonthaburi linking 5 lines along a major transport corridor.
The Pink Line was originally intended to be a heavy rail line but this was changed to dual-track monorail in 2008 on the basis that construction costs would be cheaper. The director-general of the Office of Transport and Traffic Policy and Planning had previously stated said 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 Government Complex. A review in early 2012 was undertaken to consider the heavy rail option again. However, it was decided to proceed with the monorail plan on the basis that the overall cost would be cheaper than heavy rail. The review of the line also resulted in the addition of 6 extra stations. The environmental impact assessment for the Pink Line was finalised in late 2012. In late 2012, a request to extend the planned line east by 3.4 km from the Minburi terminus along Suwinthawongse Road to Nong Chok was submitted. However, this will was not be implemented. The expected cost of the line with the additional 6 extra stations is 55 billion baht.
The Pink line was then due to be tendered in the 3rd quarter of 2013 with construction due to commence in early 2014. However, delays in preparation of the tender in relation to the selection of monorail rolling stock and subsequent political protests resulting in a snap national election in early Feb 2014, further delayed the Pink Line tender. A subsequent coup in 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 project. The BSR also won the bid the Yellow Line project. 
On 16 June 2017, the Pink Line project contracts were signed with the BSR consortium by the Mass Rapid Transit Authority of Thailand with a scheduled operational date of 2022.  The BSR has established Northern Bangkok Monorail Company Limited to operate the monorail. The BSR proposed a 2.8km spur monorail route to link to Impact, Muang Thong Thani from Si Rat station which is waiting for approval from the government.
List of planned stations
Originally, the line was to have 24 stations, 4 of which will be transfer stations and 2 of which will be "park & ride" stations. However, 6 new stations were added in mid-2012 for a total of 30 stations.
The line will also have 2 additional service stations for train maintenance.
