Condition-based maintenance: the clue to reducing maintenance costs
In Europe alone, railway infrastructure and rolling-stock maintenance are expected to cost over €25 billion in 2022, and the cost keeps rising every year. The biggest cost drivers are tracks, wheelsets and pantographs. But there is good news too: by replacing reactive fault detection with proactive evidence-based approaches, a significant cost reduction can be made…
According to global management consultant McKinsey & Company, data-driven condition-based maintenance can lead to an overall reduction of at least 10 to 15% in maintenance costs.
From reactive to proactive repair
This is possible because condition-based maintenance entails innovative, cost-efficient methods of data collection – such as using in-service trains rather than dedicated measurement vehicles, allowing real-time monitoring of track.
Also, asset-condition intelligence can be provided directly to your maintenance teams, through customized dashboards featuring location maps, diagnostic readings and identification of the required spares.
You may recognize this: at present, some components (e.g., wheel bearings) are often replaced or refurbished before they are fully exploited. While the train is out of service for repairs, a lot of other parts are also replaced too early.
The whole idea of condition-based maintenance is to avoid such situations and to evolve towards data-driven replacements, in which every component of the train is used to its full extent – ensuring maximal efficiency and minimal costs.
Research on ROI
Rail operators should start by conducting an analysis of condition-based maintenance programs before tackling technology evaluation or even implementation. These are the elements to focus on:
the overall intent of the project analyzing the potential impact of improvements
specific costs tied to component failure and the subsequent associated expenses
a Pareto analysis of known failures together with the financial ranking of critical assets enabling the areas of priority
documentation of the projected labour costs of reductions in out-of-service time by a factor of 25%
costs associated with balancing refurbishment against replacement
