Blackstar Rail Limited provide Design for Maintainability DFM services through the practical implementation of maintainability concepts in the design of a system. Maintainability is the ability of an item, under stated conditions of use, to be retained in, or restored to, a state in which it can perform its required functions when maintenance is performed under stated conditions and using prescribed procedures and resources.

The inherent availability of a device is the maximum reliability that can be achieved if the device is operated and maintained within the desired period. The inherent reliability of a device ultimately depends on the configuration and the robustness of the component from which it was built.

Blackstar Rail Limited support the early design of rolling stock projects to develop a cost-effective maintenance strategy in the line with Reliability Centred Maintenance (RCM) techniques.
