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.
What role does rolling stock play?
Rolling stock is an essential part of a railway system. As a moving system, it is subject to external influences from the environment and static loads. Rolling stock must also bear the stress of dynamic loads and wear (by friction), particularly on the load-bearing mechanical parts, such as the car body and bogie.
Why is refurbishment important for your business?
While new rolling stock is designed for a certain projected use (in terms of operating conditions, passenger needs,etc.) and a defined lifespan, it is financially preferable for rail operators to operate these valuable assets for as long as possible. Some subsystems may need to be replaced or rebuilt on a scheduled or unscheduled basis for various reasons. This includes meeting rising passenger expectations (comfort, communication, safety), enabling more frequent use and increasing passenger capacity while ensuring safe and reliable operations until the end of the planned lifespan. Extending the lifespan of rolling stock through retrofit or upgrade work is often economically more efficient than buying new rolling stock.
