Australian mega-rail project geotechnical works begin

Geotechnical drilling work on a $2.5bn (£1.6bn) rail project in New South Wales has begun, paving the way for construction to begin on the country’s longest rail tunnels.

Drilling work at Old Northern Road in Castle Hill will help engineers determine the exact underground conditions for the 23km route and the 15.5km tunnel.

At least 150 boreholes with a diameter of up to 150mm will be drilled at various locations along the proposed alignment between Rouse Hill and Epping at depths of up to 75m to confirm underground geological profiles, rock types and site conditions.

When finished, the rail link will provide services between the North West of the state and greater Sydney.
