Since July 2015, WSP has provided design review and tender support services for the Red Line Commuter Rail works. Running a distance of 60 kilometres, the rail line extends from Rangsit to Thammasart and Ban Phachi. The works also include a rail link extension for the Suvarnbhubmi Airport Rail Link, extending 14 kilometres from Don Muang station to Bangsue station. 

Our team’s responsibilities include signalling, telecommunication systems, power supply, rolling stock, depot and workshop, railway system safety, and track-work.
