This dataset provides an indicator of historic rail occupancy for individual rail services from July 2019.

Data included in ROAM - Rail Opal Assignment Model - includes Sydney Trains (T1 - T9) and Metro (Metro North West line) services.

Note: With the introduction of the new City and Southwest Metro line, Transport is moving to a new Opal Allocation Model to handle the complexity that these new services will bring. The legacy Rail Opal Allocation Model (ROAM) data will be replaced with a new Near Real Time (NRT) ROAM from May 2024.
