Rolling Stock Maintainer and Overhauler

Efficiently Maximizing Rolling Stock Uptime

Rolling stock needs to be cost effective. It also needs to be operational and available. The last thing a freight and train operator needs is unavailable rolling stock.

As someone involved in the maintenance, repair and overhaul of trains, you also face the challenge of having to deliver in ever shortening timescales and at lower cost.


The supply chain has a major impact on the cost base of maintainers and overhaulers. It also affects their ability to meet operator demands and deliver in time. Whilst a weak supply chain threatens efficiency, an effective supply chain offers a whole number opportunities:

Challenges such as how to:

  • Ensuring parts are safe and adhere to the required standards and legislation
  • Managing a disparate and diverse supply chain
  • Ensuring the right parts are where they need to be when they are needed
  • Improving depot operations that minimise downtime
  • Making the best use of condition monitoring to add real value and bring new efficiencies to train maintenance

Increasing demands on train availability and utilisation and ever shrinking maintenance windows necessitate fresh approaches to maintenance and the provision of parts.

Supply Chain Time Savings

The supply chain has a significant impact on a freight fleet operator’s ability to meet these challenges. It does though present challenges of its own:

  • Ensuring parts availability across multiple suppliers and that parts adhere to the required quality, safety, regulatory standards.
  • Efficient maintenance and depot operations that minimise downtime.
  • Understanding and managing parts performance and its impact on overall train performance.
  • Delivering new innovation to bring new efficiencies to improve customer experience.
