Innovative trains
these design concepts for future customer convenience.
The train is fitted with newly- developed advanced test facilities including monitoring cameras, while measurement data is recorded in the main test room in the M2 car during trial running. Test runs at up to 370km/h are currently being carried out between Ulsan and Shinkyungju on the Kyungbu high-speed line to examine the characteristics of an ultra high-speed train. The main fundamental interfaces - wheel-rail, pantograph-catenary, and others needed to achieve the ultra-high- speed record - will be carefully verified at every speed-up stage to fulfill the safety guidelines for the ultra-high- speed train. A newly-developed bogie, which was successfully proven through simulation of vehicle dynamics and by roller rig test, will be tested. Modification of the active suspension to achieve stable running and a high- quality ride index might be carried out if it is required during test running. During the design stage, the
aerodynamic and aero-acoustic characteristics of the train were estimated by using commercial simulation tools in a wind tunnel test

facility. The estimated parameters will be verified during each increase in speed. Hemu430X will be rigorously tested and driven for at least 100,000km on main lines until 2015, while production trains are expected to enter commercial service in 2017. The future commercial trains based on Hemu430X will have a maximum
operating speed of between 350 and 370km/h depending on track conditions. This would enable passengers to reach any of Korea’s major cities within 90 minutes. As a result, the next generation of high-speed trains could greatly increase the attractiveness of domestic travel and promote maximum use of the high-speed network. IRJ
