The SRT Red Line in Thailand serves more than 300,000 passengers each day and extends the country’s commuter rail system into the suburban regions.
Aurecon played a key role on the Bang Sue – Rangsit section as the Track Alignment Designer, collaborating with MHSC consortium (Mitsubishi and Hitachi and Sumitomo) and the civil contractors Unique Engineering and Construction and Italian-Thai Development.
The development of the Rail Mass Transit System in Bangkok was identified as an effective measure for helping to address the congested traffic in the city, and its perimeters. The State Railway of Thailand (SRT) was the project owner of the Mass Transit System: Red Line, as the key connection between the central business district and the four compass points of suburban areas.
The 26.3 km Bang Sue-Rangsit section commenced construction in 2013 and was completed in 2020.
Aurecon designed the track alignment for five areas due to the sheer size of the project. Aurecon’s rail alignment designers produced more than 400 drawings for the project due to its size and complexity.
The best-for-project alignment design met the requirements from all stakeholders:
Aurecon worked closely with the operations team to ensure that the line speed was maximised to conform with rail operational requirements, but that a passenger’s comfort and safety was also catered for.
Aurecon’s best-fit alignment suited the constructed structures by the civil contractors, including the platform and viaduct. The horizontal and vertical deviations met the requirements and construction tolerance, to allow the track installation team to complete their work in an orderly approach.
Upon completion, the Bang Grand Station is now one of the biggest rail stations in Southeast Asia. It serves as the central hub for the Rail Mass Train System. It provides linkage to the existing northern, eastern, and southern railway routes as well as the future Red Line commuter trains and the Suvarnabhumi-Don Muang Airport electric railway line (Airport Rail Link), and the future high-speed rail project.
Traffic congestion at eight intersections where the railways cross the roads was reduced and this in turn reduced vehicle accident rates.

Auckland’s first underground railway system will reduce congestion, bring people closer to job and amenities, and unlock new development potential.
Aurecon's active transport design expertise supports TfNSW to create a seamless, unobtrusive, step-free ramp and cycleway across Sydney Harbour Bridge.
