The **Red Line Mass Transit System Project** is a [commuter rail](/source/Commuter_rail) system serving the [Bangkok Metropolitan Region](/source/Bangkok_Metropolitan_Region) in Thailand. The system consists of two lines; the [Dark Red Line (Bangkok)](/source/Dark_Red_Line_(Bangkok)), running from [Thammasat University](/source/Thammasat_University)'s [Rangsit](/source/Rangsit%2C_Thailand) campus to [Maha Chai](/source/Maha_Chai) in Samut Sakhon Province, and the [Light Red Line (Bangkok)](/source/Light_Red_Line_(Bangkok)), running from [Salaya](/source/Salaya%2C_Thailand) in Nakhon Pathom Province to [Hua Mak](/source/Hua_Mak_Railway_Station) in Bangkok, with both passing through [Krung Thep Aphiwat Central Terminal](/source/Krung_Thep_Aphiwat_Central_Terminal), which connects to the [Blue Line](/source/Blue_Line_(Bangkok)). Financed through an aid grant from the [Japan International Cooperation Agency](/source/Japan_International_Cooperation_Agency) at a cost of [¥](/source/Japanese_yen)166.9 billion ([US$](/source/United_States_dollar)1.6 billion),[2] construction began in January 2009; free public trial operation began on 2 August 2021, the same day that Krung Thep Aphiwat Central Terminal opened; and full commercial service of the lines began in November 2021.[3] It is part of the [Mass Rapid Transit Master Plan in Bangkok Metropolitan Region](/source/Mass_Rapid_Transit_Master_Plan_in_Bangkok_Metropolitan_Region).

Most of the railway runs alongside existing national railroad tracks, eventually replacing them. Segments running through inner-city areas are elevated, and the system is electrified by [overhead lines](/source/Overhead_lines). The system was developed and is owned by the [State Railway of Thailand](/source/State_Railway_of_Thailand).[4][5] Since the Red Lines run roughly along the alignment of the failed [Hopewell Project](/source/Bangkok_Elevated_Road_and_Train_System), they have been described as a "Hopewell revival".[6]

"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."
