We’re on the map!
Why GLRL?
• Provide sustainable development for the wider South West Growth Centre
• Provide direct transport link to/from the city • Improve services through congestion relief
and extra capacity for the south west region
• Minimise environmental impacts
What is GLRL?
• Rural location • 12 km track • Two stations • One stabling yard (20
trains) • 14 bridges plus culverts • Hume Highway • Deep cuttings • High embankments • Electrical substations
Project requirements
• Reference design • Environmental Assessment • Land purchases • Ministerial conditions • RailCorp standards and TPD Works Brief • Design and construction contract • Systems engineering and assurance
Key challenges
• Route is sinuous • Through open paddocks • Stakeholders • Safety in design • Drainage and flooding • Rail systems • Rail and NSW
experience • Design changes

Keys to Success
• Safety – starts in design – continues through integration of the design &
approvals – into construction, use and maintenance – Safety In Design monthly awards – JH National Group Award for 2012
• Systems Assurance – Through all stages of design, construction &
verification
Hume Highway Underpass
• RMS requirements • Two x four lane highway with 15m median • 79.5m in length • RailCorp requirements • Two tracks, walkway and refuges • Geology • Design and construction
