It 18 per cent of the track length passes through tunnels (more than 90km) and about 21 per cent through viaducts. The trains travel at an average speed of 300-350 km/hr.

Coordination and supervision of site investigations along the high-speed train line. Geodata proposed, developed and applied a web-based geographical information system (GDMS) to monitor the progress of site investigations and for sharing data obtained in real time. After completing the site investigations, Geodata performed a risk analysis (RA) of the entire alignment based on the results obtained as well as the geological mapping and studies. The RA allowed Geodata to recommend the client alignment modifications and improvements.
