A range of key rolling stock technologies oriented at achieving the overall S2R Master Plan objectives (high reliability, high capacity, low cost and improved performance) need to be developed to a point that enables the future development of the demonstrators foreseen in S2R. These high level objectives are influenced by many functional elements of the vehicle, so the fundamental challenge to be addressed is to define the specific solutions at sub-system level which will work together to produce the desired benefits at system level. The following individual challenges placed at the different rolling stock subsystems can contribute to these objectives:
Carbodyshell: The challenge is to develop lighter carbodyshells which make full use of the possibilities of composite materials including integration of functions. This is linked to identifying the specific design principles, materials and manufacturing processes that fulfil the requirements set in previous activities30, in terms of material properties, manufacturing cost and certification.
Running Gear: The challenge is to develop and combine adequately suitable technologies to produce light, low noise, track friendly, reliable, low LCC running gear.
Brakes: The challenge is to develop the future brake system concept based on complementary technologies and considering both adhesion-dependent and adhesion-independent approaches, leading to a full system approach with efficient brake force generation and reduced noise emissions.
Accessibility and Doors: The challenge is to provide seamless and flexible access to the train to persons with reduced mobility, while reducing the weight and the cost, improving the comfort features (noise, thermal, etc.), and adding functionalities of door and access systems.
Modular interiors: The challenge is to identify and define modular, flexible approaches for the design of train interiors including driver’s desk, taking into account new generation of driver´s simulators. This approach search to increase/adapt seating capacity, to improve/adapt passenger flow in and out the train and to increase passenger comfort.
30 FP7 Refresco project, H2020 Roll2Rail project
The completion of all these challenges, along with the activities already started in the areas of TCMS, Traction and Brakes as a result of the S2R JU 2016 calls for proposals, will contribute to the achievement of the objectives set out for IP1 in the S2R MAAP, as described here below.
Scope: In order to address the challenges described above, the proposals should address all the following work streams, in line with the S2R MAAP:
Carbody Study (TD1.3): Building on the work carried out towards the creation of a regulatory framework for the use of composite material in structural applications in trains and the activity carried out in the REFRESCO project, and on the definition of the technical specification of the prototypes to be built in S2R which is already being carried out in H2020 ROLL2RAIL project, the work should focus on the selection and benchmarking of material and manufacturing alternatives, the definition of material characterization and the certification process associated. The activity is expected to prepare conceptual design solutions up to TRL3.
Development of concepts & technologies towards future running gear (TD1.4): A multi-technology approach will have to address several functions of running gear (comfort, curving, structural function, rolling components, health monitoring, etc.). Proposals should address the following aspects: technical specification of future running gear; innovative sensors for condition monitoring; new or improved materials for bogie frames and wheelsets; methodologies for the prediction of running gear noise & vibration; concepts for noise reduction; and certification and safety methods/tools for active and passive control systems; and address possible certification issues for all such potential technologies developed. The Universal Cost Model methodology being developed in the Roll2Rail project will be used to evaluate the benefits of the proposed developments. The activities are expected to prepare specific conceptual design solutions up to TRL3.
Development of future noise-reduced brake system solutions (TD1.5): the work should focus on a full system approach with efficient brake force generation based on complementary technologies (innovative friction pair solutions, electro-mechanic solutions & adhesion independent frictionless low-noise brake system solution (e.g. next generation Eddy current brakes)), incl. the development of proposals for the technical standardisation of the assessment of brake system and virtual certification. The activities are expected to reach TRL3, including the development of specific conceptual design solutions.
Development of innovative concepts towards new generation of door system (TD1.6): The proposals are expected to address the following aspects:
Adaptable gap filler for easier and independent access for Persons with Reduced Mobility (PRM) compatible with the 2 standard European station platforms (550 mm and 760 mm) and vertical gaps up to 200/250 mm compatible with existing and future station platforms.
Integration and utilization of new technologies for door entry surveillance and passenger information.
Selection of metallic, plastic or composite materials, material characterization, architecture and integration of new metallic and composite technologies of the leaves for weight, comfort and energy optimization.
The activities are expected to reach TRL3, incl. development of specific conceptual design solutions.
Development of concepts towards new generation of interiors modularity (TD1.7): Activities are expected to start with an analysis of the state of art of technical possibilities for a modular design interior including for example seats, tables, interiors ambiances, screens and driver’s desk from different transport modes (railway, aircraft interiors, etc.).
Both for new generation of drivers’ cab and ultra-light seats, this topic call will feed specifications to the complementary topic S2R-OC-IP1-01-2017 in September 2018 at the latest. As a result, the opportunities of Modularity In Use will be identified and will lead to the development of a range of specific conceptual ideas. The activities are expected to reach TRL 3 or 4, including the development of conceptual design solutions.
The new concepts resulting from any of the proposed activities will be supported by cost-benefit analyses that will be used as the basis to justify higher TRL developments. The activities will consider, when applicable, suitable works to prepare for future technical standardisation related to the proposed innovations.
The implementation of this action requires close collaboration with ROLL2Rail project (‘lighthouse’ project resulting from H2020 call MG2.3-2014) 31.
31 However, as the EC Work Programme 2014-2015 does not contain sufficiently detailed requirements, the provisions on complementary grants in the S2R MGA are not mandatory for the beneficiaries of Roll2Rail project , who may accept them on a voluntary basis, subject to their explicit agreement.
The action that is expected to be funded under this topic will be complementary to the actions that are expected to be funded under the following topics:
S2R-OC-IP1-01-2017: Innovative materials & modular design for rolling stock applications
S2R-OC-IP1-02-2017: Tools, methodologies and technological development of the next generation of Running Gear
S2R-OC-IP3-01-2017: Future stations and accessibility
S2R-CFM-IP3-01-2017: Smart system energy management solutions and future station solutions
S2R-CFM-IP5-01-2017: Real-time information applications and energy efficient solutions for rail freight
The action stemming from this topic will also be complementary to actions carried out within the following topics:
S2R-CFM-IP1-01-2016: Development of concepts towards the next generation of traction systems and management of wheel/rail adhesion
S2R-CFM-IP1-02-2016: Development of new technological concepts, standard specifications and architectures for train control and monitoring, with specific applications in train-to-ground communications and high safety electronic control of brakes
S2R-CFM-CCA-02-2015: Energy and sustainability, including noise and vibrations baselines assessment
As specified in section 2.3.1 of S2R AWP for 2017, in order to facilitate the contribution to the achievement of S2R objectives, the options regarding 'complementary grants' of the S2R Model Grant Agreement and the provisions therein, including with regard to additional access rights to background and results for the purposes of the complementary grant(s), will be enabled in the corresponding S2R Grant Agreements.
The S2R JU will only fund one proposal under this topic.
Expected Impact: The most significant benefits expected from these actions, once the technologies developed are fully implemented and deployed, are:
Significant weight reductions in major sub-systems of railway vehicles, such as car-bogies, running gear, doors and train interiors. This weight reduction will have several side effects such as:
Reduction of the energy consumption of the vehicle
Increased track friendliness
Additional freedom for vehicle design
Reduction of the Life Cycle Cost of the vehicle and the whole railway system, reduction of track damage and improved health monitoring
Increase in passenger comfort, improved access systems and insulation, reduction in noise emission and transmission in running gear and brakes and additional flexibility for the interiors
Increase in components reliability
Improved passenger experience and accessibility.
Increase in passenger capacity by new kinds of comfort seat for high density train and by innovative compact and flexible driver’s desks.
Specific metrics and methods to measure and achieve impacts should be included in the proposals, with the objective to achieve by the end of the S2R Programme the “Specific Achievements” quantitatively and qualitatively defined in the S2R MAAP related to TD1.3, TD1.4, TD1.5, TD1.6 and TD1.7 in line with the relative Planning and Budget.
