Labor has promised $2.2 billion for Brisbane’s cross-river rail project if they win the next election.

The Queensland government had committed to fully funding the $5.4 billion project after failing to secure money from the Turnbull government.

The project is a 10km line to run between Dutton Park and Bowen Hills, with four new underground stations at Boggo Road, Woolloongabba, Albert Street and Roma Street.
