The Brisbane to Gold Coast rail line connects Gold Coast City and Logan City with the Brisbane CBD.
The rail line moves approximately 20,000 passengers during the combined morning and afternoon peaks each day. The rail line has seen strong growth in passenger demand, driven by population growth in the Brisbane to Gold Coast corridor.
The existing rail line is two tracks south of Kuraby station and three tracks to its north. This line is subject to a range of constraints, including tight curves that limit line speeds, and level crossings and station infrastructure that limit additional tracks.
Express services between the Gold Coast and Brisbane must share a single track with ‘all stops trains’ between Kuraby and Beenleigh. This limits the number of services that can be provided to support growth in travel demand between the cities of Brisbane, Logan and the Gold Coast. These infrastructure and operational constraints are resulting in overcrowding during peak periods.
Failure to address these capacity constraints could lead to potential rail users choosing to use the already congested M1 Motorway. This would result in additional travel times, with nationally significant impacts on productivity.
Options for this initiative could include:
- rail line and station improvements between Kuraby and Beenleigh to allow for the separation of express and all stops services
- increased frequency for Beenleigh and Gold Coast services in both directions
