The Light Blue Line (Din Daeng – Sathon) was a planned monorail line to be built in Bangkok, Thailand. Its path runs along a north–south axis. This line is planned to link the Din Daeng housing community areas, Bangkok City Hall 2, Makkasan Station (for the Suvarnabhumi Airport Link), and business area along Sathon Road.

The total distance of the route is approximately 9.5 km and is expected to service 319,000 passengers per day. The line is tentatively planned to be completed by 2029.


The Yingluck Shinawatra led Phua Thai government elected in July 2011 decided not to pursue plans to continue the Grey Line and the Light Blue Line, citing that the lines are not feasible within their 4-year, 10 lines priority plan. The Bangkok Metropolitan Administration was invited to could both projects but the BMA would have to fund them.[1] As of 2013, BMA has taken on the Grey Line project.

As of the middle of 2014, there are no plans to implement the Light Blue line by the BMA. Given the delays in 2013 and 2014 with tendering other priority mass transit lines related to the political crisis in Thailand, it is highly unlikely that the Light Blue line will be considered by either the BMA or the MRTA for many years.


The route has a total of 9 planned stations.
