State Railway of Thailand (SRT) Red Line


The Red Line Mass Transit System Project is a commuter rail system serving the Bangkok Metropolitan Region in Thailand. The construction began in January 2009 and free public trial operation began on 2 August 2021, with full commercial service to begin in November 2021 when Bang Sue Grand Station opens. It is a part of the Mass Rapid Transit Master Plan in the Bangkok Metropolitan Region.

The system consists 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.
