Martinus Inland Rail

Challenge

Inland Rail will improve freight capacity between Melbourne and Brisbane by upgrading track for double stacked container movements. As the project is on an operational corridor, Martinus needed to demonstrate construction completion and clearance compliance following each section of track upgrade to confirm that double stacked freight trains could operate on the network.

Solution

An original clearance register has been established for Martinus based on MLS data previously recorded by Agonics and this needed to be updated as construction had progressed. To record new datasets Agonics mobilised its MLS system onto a hyrail vehicle and captured the Albury to Parkes corridor.

The Agonics XERRA® software was configured to recognise adjacent rail track gauge points to support Kinematic Envelope (KE) to KE minimum airgap assessments through complex track arrangements and with correct curvature and cant parameters.

Turnouts where tracks interfaced with the new Inland Rail alignment were carefully modelled to ensure that the end-throw of entering and exiting trains would not encroach into the clearance space required for Inland Rail traffic.

Incursion reports were automatically generated in XERRA with unique profile IDs provided to Martinus for easy review and validation in the XERRA platform.

Outcomes

• The MLS campaign recorded zero OHS incidents with full data coverage achieved.
• Comprehensive clearance assessments were completed using authoritative LiDAR point clouds.
• Inland Rail and Martinus project teams are able to share clearance results and bookmark work site observations using the XERRA® platform.
