Rail Underpass tunnel pushes below passenger line
Great things have happened at North Strathfield, as the North Strathfield Rail Underpass Alliance pushes a tunnel for freight trains under the existing passenger rail. The tunnel will allow freight to move more easily from the main North Line at North Strathfield, westward towards Flemington.
The North Strathfield Rail Underpass Alliance is constructing the rail underpass under the Main North Lines at North Strathfield, removing the need for freight trains to cross over the existing tracks before they continue their journey towards Flemington.
The project forms part of the Northern Sydney Freight Corridor Program, a joint initiative of the Australian and NSW governments to improve the capacity and reliability for freight services between North Strathfield and Newcastle.
The project has been designed for Transport for NSW by NSRU Design Joint Venture (SKM & PB) and Mott Macdonald.
The key features of the project include:
• a new rail underpass for freight trains at North Strathfield
• new track to connect to the existing relief goods loop at North Strathfield
• 2.4 km of new track and upgrade of 850 m of existing track
• a new aerial concourse and the installation of four new lifts at Concord West station.
• relocation of an existing RailCorp depot at North Strathfield Station
• associated civil and structural works
• provision of new rail systems, including overhead wire, high voltage, low voltage, communications and signalling
The project is being delivered by Transport for NSW, John Holland Group and Bouygues Travaux Publics Australia.
A road header is excavating the tunnel underpass and 12d Field software is being utilised for all set out and conformance on the project. A Beta version of 12d Model 11 is allowing the project surveyors to use the new tunnel set out tools and the trimesh for conformance checking. In the early stages of construction, Mick Gunter, 12d Solutions Senior Programmer, visited the site and collaborated with the alliance survey team to provide valuable feedback which was incorporated into the 12d Field tunnelling module.
Dave Mares (Alliance Survey Manager) said that “12d Field exceeded their expectations on this project, and its features surpassed the overseas software traditionally used for this type of project”. Dave will be presenting at the 12d Model International User Conference about the use of 12d Field on the North Strathfield Rail Underpass project.
