Design & Delivery

AERA1 is the private concessionaire for this railway project which aims at creating a new High Speed Rail system in Thailand connecting Don Muang, Suvarnabhumi and U-Tapao airports whilst upgrading and extending Airport Rail Link (ARL) commuter rail services to Bangkok city center.  It covers a route of 220 km standard gauge double-track line, with 15 stations (Makkasan, main station, will be developed on 24ha) and 2 depots / maintenance bases to operate 250kph high-speed services.

The design services will involve different Group entities in France, India, Korea and Singapore, as well as the mobilization of an on-site team for the PMC support.
