Ensure safe retrofit and upgrade of your existing rail fleet
The challenges associated with renewing and upgrading railway systems – in particular rolling stock – have increased significantly in recent years. Hardware and software lifecycles are shrinking in comparison with the decades-long lifecycles of the electro-mechanical systems that they interact with. Meanwhile, operational stress is on the rise due to higher performance requirements and busier schedules. Handling the process of upgrading and system modernisation can be further complicated, as certain parts will have to be renewed due to wear and tear, while other parts are simply no longer available from the original supplier. Operating companies are also facing additional pressure from higher safety requirements and increased passenger demands. Extending the lifespan of rolling stock through retrofit or upgrade work is often economically more efficient than buying new rolling stock.
