Conclusion
Obsolescence in the rail industry

This article illustrates obsolescence in the rail industry, particularly in electronic and mechanical parts. It describes the obsolescence problems encountered in maintaining rolling stock in working order for a service life of 40 years. This means maintaining the supply of parts, the underlying know-how, or successfully replacing parts while maintaining their conformity. To achieve these objectives, various methods can be implemented, such as the use of 3D printing.

The implementation of a circular economy is also an interesting solution. The circular economy encompasses a number of principles that enable a product's use to be extended, thereby delaying or anticipating the effects of obsolescence. It is still under development in the rail industry. Developing a circular economy strategy in this sector could help minimize the consequences of obsolescence, while...
