The Red Line Mass Transit System Project is a planned commuter rail system to serve the Bangkok Metropolitan Region. The construction began in January 2009 and will be completed by the end of 2020. It is a part of the Mass Rapid Transit Master Plan in Bangkok Metropolitan Region.

The system will consist of two lines, one (also referred to as the SRT Dark Red Line) running from Thammasat University's Rangsit campus to Maha Chai in Samut Sakhon Province, and the other (SRT Light Red Line) running from Salaya in Nakhon Pathom Province to Hua Mak in Bangkok, with both passing through Bang Sue which will act as a connecting hub to the MRT system.

As of 2018, the Bang Sue – Taling Chan segment of the Light Red Line is completed, and the Bang Sue – Rangsit segment of the Dark Red Line is under construction. Most of the railway will run alongside existing national railway tracks, eventually replacing them. Segments running through inner-city areas will be elevated, and the system will be electrified by overhead lines. The system is to be owned and is being developed by the State Railway of Thailand.[1][2] Since the Red Lines run roughly along the alignment of the failed Hopewell Project, they have been described as a "Hopewell revival".[3]

"This Northern Commuter has to connect with the Airport Link which is not even at the design stage. At the minimum, the detailed design for the Airport Link must be done by July 2004. The Hopewell revival will be an elevated single floor--either shared tracks or separated tracks for High Speed Rail, DMU/Diesel Tracks, and Red Line Commuter which all have to be done in six years. The elevated section will end at Don Muang and then it will be at grade with separated tracks."
