Coomera to Helensvale Duplication Project

Services are now operating on the new duplicated section of the Gold Coast line, between Coomera and Helensvale stations.

The $163 million project completes the 'missing link' on the Gold Coast line and delivers improved reliability for Gold Coast customers, and increased capacity for the 2018 Commonwealth Games and for the future.

Queensland Rail would like to thank the local community for their cooperation and patience throughout works.

What is involved?

The Project involves duplication of the rail line between Coomera and Helensvale stations, including:

  • Construction of eight rail bridges across waterways and roads along the corridor
  • Construction of 8.2 kilometres of rail track, including overhead electrification system and signalling systems
  • Construction of a maintenance access road adjacent to the new rail line
  • Replacing approximately 3.8 kilometres of timber barrier fencing with concrete barriers
  • Replacing approximately 15 kilometres of chain wire fencing to secure the rail corridor.

Project benefits

The project will deliver a range of benefits for the Gold Coast and south-east Queensland, including:

  • Increasing rail capacity on the Gold Coast line to support the Gold Coast 2018 Commonwealth Games
  • Improving safety, efficiency and reliability of the network and a reduction in delays
  • Reducing transport-related impacts on the natural, cultural and built environments
  • Providing increased future capacity on the Gold Coast line, dependent on inner city capacity and rail corridor enhancements.

Project summary

Bridge works

Eight bridges (totalling 1.4 kilometres in length) were constructed as part of the project. The 860-metre long rail bridge across Coomera River, Hope Island Road and Saltwater Creek included a 220-metre section over the Coomera River and 33-metre through-girder bridge span across Hope Island Road.

Rail systems and track works

Rail systems and track works undertaken included installing ballast, sleepers, track and resurfacing, and overhead signalling and electrification systems.

Timber barrier and corridor fencing replacement

Existing timber barriers were replaced with concrete barriers between Saltwater Creek and the Gold Coast Highway. The project team consulted extensively with property owners along the western side of the corridor where the barriers were installed on property boundaries. Installation of the new concrete barriers was completed in July 2017.

Project works included the replacement of 15 kilometres of chain wire fencing between Coomera and Helensvale stations, completed in mid-2018. 

Corridor security

Security of the rail corridor is a key priority for Queensland Rail. The rail corridor is regularly patrolled by Queensland Police and rail security personnel.

Local community members and residents adjacent to the corridor are encouraged to report any suspicious activities to Policelink on 13 14 44 or Crime Stoppers on 1800 333 000. For emergencies call 000.

Should you identify any trespass activities inside the rail corridor please notify our Rail Management Centre on 1800 079 303.
