What major technical challenges will railroad operators be facing Rail traffic will considerably increase In Germany for instance policy makers are targeting a 100 per cent increase in passenger and a 25 percent increase in cargo transportation It s expected that there will be no proportional growth in the num ber of rail vehicles so the existing trains will have to be used more intensively and longer Propulsive power will increase as well in order to achieve low er headways and higher loading capacities For us as a component manufacturer this means that we have to offer products delivering even longer ser vice life allowing for more intensive operation 3 questions for with even longer maintenance intervals plus fea turing more compact designs than before because more space for passengers or cargo is desired In view of this requirements profile a rolling bearing quickly turns into a high tech product How is Schaeffler planning to meet these growing requirements We intend to continue driving developments with our know know in materials forming and sur face finishing technologies even in areas where we already have a competitive advantage Here s an example For iron ore trains in Australia we deliv er rolling bearings enabling an axle load of 45 to 50 metric tons 50 to 55 short tons This is twice as much as is currently required in Europe But such dimensions are important in Australia as a prereq uisite for cost efficient operation of the trains Schaeffler is increasingly emphasizing mecha tronic and digital product offerings because you feel that the end of the rolling bearing is in sight No not at all Products like our condition monitor ing solutions and the axle box generator are val ue adding offerings for our customers which they favorably respond to But rolling bearings will con tinue to exist for as long as trains run on rails Even a Hyperloop train creates contact for track ing in its vacuum tube and therefore requires roll ing bearings Maybe they ll be hyperloop pods These high speed trains are supposed to chase through vacuum tubes at jet speed of up to 1 000 km h 621 mph The first crewed tests have begun but critics of the technology remain skeptical China and Japan on the other hand are pushing the magnetic levitation train system an innova tion that was born in Germany The JR Maglev is planned to connect Japan s capital Tokyo with Na goya starting in 2027 At an average speed of far above 500 km h 311 mph it will take the train 40 minutes to cover the 286 kilometer 178 mile distance The extension of the route to Osaka is planned to be completed by 2037 with a target travel time of 67 minutes half as much as the current Shinkansen Bon voyage The Hyperloop idea is picking up momentum The American company Virgin performed the first crewed test run over a 500 meter 0 3 mile distance this fall The Korea Railroad Research Institute first broke the 1 000 km h 621 mph record with a 1 17 scale model Dr Michael Holzapfel Senior Vice President Business Unit Rail at Schaeffler 71 Outlook
