ExpectedOutcome:
DESTINATION 4 – A sustainable and green rail system
In order to improve the existing sustainability performances of railway systems, new innovative products and services need to be developed, tested and deployed. On the basis of leading-edge technologies to minimize the overall energy and resource consumption and environmental impact of the railway system, the aim of this destination is to accomplish a more attractive and climate resilient mode of transport. With the cooperation of the whole European rail value chain, the target is to optimise performances, stimulate the modal shift and improve passenger experience. Given the level of investments needed towards decarbonation of the overall rail system, the R&I activities will contribute to the objective of a Climate Neutral Europe for 2050. This means:
- Innovative solutions to minimise environmental footprint of the overall rail system., including less resource-intensive materials (infrastructure, rolling stock and operational).
- Holistic approach towards generation, storage and optimal use of energy in the infrastructure connected to the European energy network.
- Innovative approaches to design and use, focused on increased capacity and modularity of solutions (tools, manufacturing processes and efficient use of resources)
- Systems improvement including electro-mechanical components for low consumption, low emissions, low noise and low vibration levels.
- Healthier and safer subsystems such as air-filtration, disinfection systems and eco-friendly HVAC technologies.
- New designs of rolling-stock especially modular interiors for a more adaptative, attractive and economically sustainable railway transport for passengers and supported by industrial standards.
The selected proposal for funding under this Destination will be a Flagship Project of Europe’s Rail with significant expected impacts, which require an integrated sector systemic approach. Proposals, should therefore set out a credible pathway (including an exploitation plan) to contributing to all of the following expected impacts as described in the Master Plan.
|
Meeting evolving customer requirements
|
Improved EU rail supply industry competitiveness
|
Reduced costs
|
More sustainable and resilient transport
|
Improved performance and capacity

These can be further detailed with specific impacts of this destination, as:
- Reducing energy consumption. The continuous technologies evolution leads to significant decrease of energy consumption. Acceleration towards a zero CO2e emission rail system.
- Bosting alternatives to the use of fossil fuels are unavoidable for the overall European rail system. Every potential solution, mainly energy storage system and hydrogen (H2) have to be considered.
- Defining the industrial standards that will support the need to demonstrate and prove rail as the greenest mode of transport, easing the transformation of the rail system in a circular economy model while ensuring resilience to external risks, such as climate change.
- Regarding the attractiveness of the vehicles, shared concepts and the relevant industrial standards will ease quicker and greener transformation of the European rail vehicles.

Interaction with the System Pillar
The System Pillar aims to guide, support and secure the work of the Innovation Pillar (i.e. to ensure that research is targeted on commonly agreed and shared customer requirements and operational needs, compatible and aligned to the system architecture), and the Innovation Pillar will impact the scope of the System Pillar where new technologies or processes mean that innovations can drive a change in approach, as well as delivering detailed specifications and requirements.
In this respect, the necessary resources would have to be dedicated to areas linked to System Pillar conceptual and architecture works – particularly addressing specification development (the interaction is illustrated in the System Pillar – Innovation Pillar interaction note (Annex VI of this Work Programme). The alignment of the activities will primarily take place during the Grant Preparation Phase and ramp up phase of the awarded proposal, and there will be continued interaction through the life of the project.
