Metro systems worldwide face a growing challenge from ageing infrastructure. Without clear end-of-life management strategies for metro assets, operators face significant operational and financial risks, including in-service failures, service disruptions, and costly emergency replacements.
End-of-life management is an ongoing process that assesses whether assets should be replaced, refurbished, or have their service life extended. This evaluation considers multiple factors, including design life, technical condition, operational performance, economic viability, regulatory compliance, and component obsolescence.
The study benchmarks global best practices for managing ageing metro assets. Drawing on data from 32 metro systems with experience across the full asset lifecycle, it provides recommendations for effective end-of-life asset management.
