The Victorian tram and train networks operate on a Franchise Model that includes both the operation and maintenance of the networks’ assets, with the contracts managed by Public Transport Victoria (PTV). PTV identified that to better manage investment decisions and to prepare for the next franchise contract, it needed a more comprehensive understanding of the long-term condition of its assets whose lifespan far exceeds rail franchise contract terms. This paper outlines the steps PTV undertook to kick-start the journey of enhanced asset knowledge through the delivery of Phase 1 of the Asset Condition Assessment Program (ACAP).
During Phase 1, a suite of asset condition assessment guidelines was developed and baseline asset condition assessments for every asset type within the metro rail and tram infrastructure, rolling stock and OCMS asset classes were undertaken. The team developed a data rich framework which represents a paradigm shift to the transport sector’s view of asset condition by understanding the life ending dominant failure modes of assets and identifying metrics to repeatedly measure the lead indicators of failure.
Phase 1 of ACAP is due for completion by July 2019 and is expected to demonstrate the following outcomes that will be presented to the audience:
• A repeatable and scalable method to define and track long term failure modes
• A data driven approach to identifying optimum representative samples of assets to monitor
• Visualisation techniques for aggregating asset remaining useful life to asset class and network health
• Lessons from data collection in a brown field environment and how we intend to tackle these for Phase 2 and beyond.
