WP22 is aiming to propose solutions to enhance the efficiency of Rail Freight transport. At the beginning a large forwarder operating long distance combined trains across Europe and a Car carrier operating a fleet of more than 3500 wagons involved in multimodal logistics across Europe and being also an ECM for other wagon operators have expressed their most urgent needs to increase their efficiency by reducing their operating costs while improving the quality of service. The tools that this work package wanted to develop was to increase the usable length of a standard train with new wagon designs having a lower LCC. At the same time improving the asset rotation with synchronous braking of all wagons could have reduced the wear and tear of the new composite brake blocks aiming at reducing noise. Several designs have been studied for car carrier wagons reaching 5 bodies with 6 axels for an overall length of around 62m. For container traffics two ideas have been studied. The first one was to introduce in a standard train composed of wagons capable to carry 40’ containers or 40’ plus 20’ containers a partial flexibility to transport a third container type of 45’ without lengthening the trains and with minimal changes on the wagons. The second idea studied was a new design of a 5 bodies wagon with 6 bogies for an overall length of around 72m. This solution was aiming to reduce the number of bogies and hence the maintenance cost. A third idea was to develop the same concept for transport of crane-able semitrailers with a 4 bodies wagon with 6 bogies for an overall length of around 67M. Each of these solutions were studied successfully in term of stability with the mathematical programs of KTH. The cost of these new designs were estimated by NTnetAB and the operational efficiencies calculated when possible or estimated according to expert experience. The impact in terms of temperature reduction with synchronous braking showed a significant decrease on the test benches of Knorr Bremse. Unfortunately new braking methodologies by applying successively strong braking followed by a release have reduced the temperature reached by the blocks and the wheel treads in a zone where the impact of the synchronous braking would not bring significant maintenance cost reduction and damage reduction. For the new wagon designs the cost benefit analysis show interesting progress for the car carrier wagon and the container wagon but not for the pocket wagons. The flexibility of putting a third of the number of container with a length of 45’ without lengthening the train may be very promising. Finally an extremely promising field is to significantly reduce the preparation time before the departure of the train with the introduction of an EOT (End of Train) device. This intermediate deliverable will be completed in the next issue with the introduction of these new designs on the Network and with a possible roadmap to mobilize investors to create these new wagons.
