The TrackStar consortium also includes Aurecon, Aecom and Hassell, which will be responsible for design, while Golder Associates will carry out geotechnical work on the project.

The 12.6km double-track line from Petrie to Kipper-Ring will become part of Queensland Rail's Brisbane Citytrain network and is considered crucial to relieve road congestion in southeast Queensland. The project includes the construction of six new stations.

Construction began in July 2012 on the first phase, which involves modifications to the road network and construction of overbridges in Mango Hill. Major works are expected to begin later this year on the second phase, which encompasses construction of the alignment, track, and structures. Commercial services are expected to start at the end of 2016.

The Australian government is contributing $A 742m to the $A 1.15bn project, with additional funding coming from the Queensland government which will contribute $A 300m (plus land), and the Moreton Bay Regional Council which is providing $A 105m.
