Work starts for design of high speed rail tunnels
Work has started locally to determine the best route for a proposed high-speed rail link connecting the region to Sydney.
Two drilling rigs have started work on the Hawkesbury River at Brooklyn and in Brisbane Water as part of geotechnical investigations to determine the optimum route alignment, according to Member for Robertson Dr Gordon Reid.
"Assembling the two barges took three days.
"They will drill six boreholes, some to a depth of 140 metres, in locations within Brisbane Water and the Hawkesbury River, with the barge on the Hawkesbury River to operate for about two months.
"The rock and sediment samples will be analysed, with the results helping inform construction methods and key details such as the design and depth of potential rail tunnels.
"The geotechnical work - which involves about 27 boreholes in key areas between Newcastle and Sydney - helps with planning for rail tunnel depths, recognising the geological complexities of traversing the escarpment into the Central Coast and on to Sydney and Newcastle."
Dr Reid said the Federal Government was planning for a future high-speed rail network to connect Brisbane, Sydney, Canberra, Melbourne and regional communities across the east coast of Australia.
"The first stage connects Newcastle to Sydney via the Central Coast with a fast, reliable and regular link between the two largest cities in NSW."
He said the line would connect the region to Sydney "in just 30 minutes".
The work was being coordinated by the Australian Government's High Speed Rail Authority as part of the business case being developed for the first stage connecting Newcastle to Sydney, he said.
He said the Government had committed $500 million for the planning and corridor protection of the Newcastle to Sydney section, and established the Authority to conduct the work.
The business case for the Newcastle to Sydney stage was due to be presented to the Government by the end of the year.
