The transportation industry has for a long time been engaged in the application of new lightweight materials for primary structural design in an effort to develop more energy efficient structures to meet low emissions targets without compromising public safety. This is also true for the rail industry, but the implementation of new lightweight materials has been slow mainly due to the lack of suitable certification procedures addressing the specific operational requirements of a railway vehicle. Such procedures are necessary so that rail vehicle manufacturers and operators can be confident that rolling stock made of a new material will perform as intended and will be at least as safe as a vehicle made out of the material it replaces. The REFRESCO project aims to achieve this goal by creating the regulatory framework for the use of new structural materials in rail car bodies. The existing certification procedures will be analysed, gaps identified and test and assessment methodologies for both isotropic and orthotropic materials will be developed. It is expected that the output from REFRESCO will accelerate the implementation of new materials in transport applications improve the competitiveness of transport industries, ensure sustainable, efficient and affordable transport services will be available and will create new skills and job opportunities through research and development in new material technologies.

EURAXLES is a 3 year R&D project uniting 23 partners across Europe including 6 axle manufacturers, 4 railway operators/IMs, 2 system integrators, 3 technology suppliers, 5 universities, 2 rail sector associations and 1 consulting firm. The consortium is well-positioned to provide a common R&D approach to axle design, protection, inspection and maintenance which will have an impact on standards, regulations and on the market. EURAXLES aims to develop innovative, safer solutions for railway wheelsets with improved reliability in a cost effective way. The research is summarized below. 1. A design approach will be developed, including a risk analysis method which could offer a simple design route by combining loads with difference occurrences including loading specificity of vehicles and service conditions together with the axles resistances, including new materials and methods in order to predict the failure probability. 2. New developments will also include (i) improved axle protection against corrosion, including protection of already corroded axles; (ii) improved adhesion of coatings with a study of the roughness influence (adhesion and fatigue behavior); and (iii) new, innovative coating solutions. The new solutions will also aim to fulfill environmental requirements to avoid or limit VOC emissions. 3. New/improved NDT inspection methods will allow the in-service inspection of axles in order to guarantee safe service conditions with a low impact on the vehicle availability. 4. A RAMS/LCC analysis of the solutions will be carried out. The railway transportation system requires a risk analysis of the safety components. Activities will improve design validation and inspection technologies of axles which will optimise costs, safety and environmental compliance to be shown with RAMS/LCC analyses. Results will be disseminated to the different stakeholders and the European standards/regulations for railway axles and wheelsets will be improved across Europe.

The ROLL2RAIL project aims to develop key technologies and to remove already identified blocking points for radical innovation in the field of railway vehicles, as part of a longer term strategy to revolutionise the rolling stock for the future. The high level objectives of the work are to pave the way to: Increase the capacity of the railway system and bring flexibility to adapt capacity to demand Increase availability, operational reliability and therefore punctuality of the vehicles Reduce the life cycle costs of the vehicle and the track Increase the energy efficiency of the system Improve passenger comfort and the attractiveness of rail transport Specific developments are proposed the scope of ROLL2RAIL: Basis of a radically new traction technology based on emerging electronic components leading towards more energy-efficient traction, which is lighter and more reliable while reducing the noise emitted New wireless technology applied to train control functionalities will allow more flexible coupling to increase line capacity Carbody solutions based on lightweight composite materials to reduce weight A way of quantifying the life-cycle cost impact of new technological solutions for running gear; Knowledge database of the variety of requirements in Europe for the braking systems to bring down barriers to step-change innovation in this area Standardised methodologies for assessing attractiveness and comfort from the passengers point of view Methodology for noise source separation techniques allowing implementation of novel and more efficient noise mitigation measures It is also the objective of ROLL2RAIL to serve as a preparation for a fast and smooth start up of the large scale initiative SHIFT2RAIL. All ROLL2RAIL results will ultimately lead to demonstration in real vehicles or relevant environments in SHIFT2RAIL.

A railway vehicle comprises a traction system including an asynchronous electric motor or a synchronous electric DC motor operable by an inverter electronic drive system. The vehicle further comprises an electronic control unit coupled to the traction system and configured to receive signals/data/commands indicative of operating conditions of the vehicle and of the traction system and to determine, based on the received signals/data/commands, the occurrence of a coasting condition of the vehicle and the occurrence of an exit condition from the coasting condition of the vehicle. If a coasting condition of the vehicle occurs, the electronic drive system is controlled to cause the electric motor to undergo magnetic flux changes. If an exit condition from the coasting condition occurs, and depending whether the electronic drive system is on or off, the electronic drive system is controlled to increase torque of the electric motor or to reduce magnetic flux reduction.

An energy-absorbing device, in particular for a rail-car, extends along an axis and has an attachment member, which can be connected to a fixed structure, an impact member, designed to withstand an impact, and an energy-absorbing member, constituted by a first tube and a second tube, which are coaxial and are made of composite material in order to collapse and hence absorb energy in the event of impact; the first tube is fixed to the attachment member, whereas the second tube is fixed to the impact member and is axially slidable, during impact, guided by the first tube; the radial thickness of the two tubes decreases along the axis, towards their free ends; in a non-collapsed resting condition, the axial gaps present between the two free ends and the attachment and impact members are substantially the same so that the two tubes start to collapse simultaneously in the event of impact.

A method for controlling the switching of an inverter, a bridge of which is adapted to chop a voltage from a direct voltage source for feeding a chopped voltage to a primary of a transformer; the inverter comprises a diode rectifier circuit receiving the input voltage from the secondary of the transformer in order to achieve a voltage fed to a chopper which feeds a load. The method comprises: a step in which the switches of the bridge are driven so that the power source is disconnected from the primary, the terminals of which are connected to each other by at least two of the electronic switches and recirculation diodes of the bridge itself, so that the voltage present on the secondary of said transformer is null; a step in which the switching of at least one electronic switch of a chopper branch is achieved when the voltage on the secondary is substantially null in order to minimize switching losses due to the opening/closing of the electronic switch of the chopper.
