Research: Management of Electronics Maintenance

Maintaining the electronics that support rolling stock fleets entails both repairing technology and managing obsolescence issues.  Metros’ strategy choices for electronics maintenance and repair include using in-house resources, outsourced, or a mix of both approaches. The study provided an overview of the key drivers and emerging issues related to electronics maintenance strategy. A balanced analysis considering costs of establishing and maintaining in-house staff and facilities, as well as the danger of over-reliance on outsourcing and losing the ability to remain an ‘Intelligent Customer’ should be taken into account.

A key role played by in-house teams is in the acquisition of spare parts, as obsolescence or supplier choices and finances lead to shrinking stock. Several approaches were discovered, from contractual agreements to a continuity of supply of spares, the use of alternative components and reverse engineering of parts.

As the lifecycles of electronics components are generally considerably shorter than the expected life of a train and its key subsystems, spares and supply management are essential to support the continued availability of electronics components. Regardless of the approach taken to ensuring sufficient supply of spares, developing strong relationships with key suppliers as well as leverage to maintain a strategic position appear to be a major success factor in managing electronics maintenance.
