The Brisbane to Gold Coast rail line connects Gold Coast City and Logan City with the Brisbane CBD and Brisbane Airport. The rail line moves approximately 20,000 passengers during the combined morning and afternoon peaks each day. The rail line is subject to 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 subject to a range of constraints including tight curves that limit line speeds, and level crossings. During peak periods, express services that travel from the Gold Coast into 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.
Infrastructure and operational constraints on the line have already resulted in overcrowding during peak periods. Failure to address these capacity constraints is likely to lead to more potential rail users choosing to use the already congested M1 Motorway instead. This will lead to additional travel times, with nationally significant impacts on productivity.
Additional capacity between Kuraby and Beenleigh would allow for the separation of express and all stops services, and increased frequency for Beenleigh and Gold Coast services in both directions, with associated travel-time savings and reliability improvements for passengers.
