MTM – XT2 Rollingstock Integration

Challenge

Metro Trains Melbourne (MTM) and the Victorian Department of Transport planned to introduce a new passenger train onto the Melbourne electrified network. Differences in the driver cabin design and carriage door configuration required signal sighting and platform boarding zones to be reassessed.

Any changes to network infrastructure required to accommodate the new train needed to be carefully planned to minimise services disruption and cost. Choosing the most suitable remediation strategy was a network integration challenge that needed accurate information sourced from a digital workflow rather than requiring persons to enter the corridor to simulate the new train driver experience.

Solution

Agonics translated a CAD model of the new train cabin into the same coordinate system as an existing MTM LiDAR dataset captured during a previous network survey and hosted within the XERRA® platform.

Using the XERRA® Signal Sighting module, driver windscreen extents, seating positions and head movement parameters were reconstructed from the CAD model. Signal visibility could then be assessed at hundreds of locations across the network.

The LiDAR dataset was also used to evaluate boarding ramp deployment at expected carriage door positions and identify locations where mitigation strategies may be required.

Outcomes

• Signal sighting assessments completed using a fully digital workflow.
• Existing MTM LiDAR and imagery datasets reused for rolling stock integration.
• Signal sighting and ramp reports delivered with XERRA location tags for validation.
• Ramp analysis identified locations where gap filler systems may be required.
