6. Overview of Korea’s High Speed Rail development Korea Rail Network Authority

7.  April. 2004. - The 1 st phase of 300km/h Gyeongbu high speed rail (Seoul ~ Dongdaegu)  Nov. 2010. - The 2 nd phase of 300km/h Gyeongbu high speed rail (Dongdaegu ~ Busan)  Dec. 2014. - Two additional high speed rail network (350km/h) (Honam & Seoul metropolitan high speed rail) Overview of Korea’s High Speed Rail development Korea Rail Network Authority

8.  World’s high speed railway market : 300km/h → 350km/h → 400km/h → ???km/h  To improve the speed : rolling stock & catenary system  400km/h Next-Generation high speed train (HEMU-430X) : KRNA ↔ KRRI(Korea Railroad Research Institute) Background of Development TGV ICE HEMU-430X Korea Rail Network Authority

10. Target Definition of development targets Overlap sectionNeutral section The Design Criteria The Design Program to build the system - basic design on the system - catenary system specification and the detail design Design Program to design 400km/h Catenary system - DeCATS400(Detail design of high speed catenary system 400km/h) Korea Rail Network Authority

11. Target Definition of development targets HEMU-430X Pantograph modeling 400km/h Catenary system requires : - tension increasing → contact wire & messenger wire change Core component should be developed - tensioning device, fitting, movable bracket, dropper and steady arm. etc. Interface with the rolling stock - allowable uplift force should be increased - system height, static and dynamic characteristic of steady arm. etc. Korea Rail Network Authority

12. Target Definition of development targets Mast and bracket Performance of core components and parts of 400km/h catenary system - identify the durability - configure the data base on electrical properties Evaluating measured values Verifying through the simulation Applying to the other projects Korea Rail Network Authority fitting

13. Target Definition of development targets → Test bed in KRRI Actual car test is the best method for final performance assessment of the developed catenary system - install separate test bed - upgrade existing high speed rail to 400km/h level Test bed for static and dynamic test in KRRI Plan to install a 56km-long test bed on Honam high speed rail Test run for speed increase (on the 2 nd phase of Gyeongbu high speed rail) - verify the rolling stock performance and dynamic characteristics Korea Rail Network Authority

15. DeCATS400 Major accomplishment of development KRNA succeeded in independently developing a DeCATS400 - applicable, convenient and appropriate to 400km/h Catenary parameter Check point - the plural number of designers to perform effective, rapid and precise design. Korea Rail Network Authority

16. Key point Major accomplishment of development Enhanced strength, conductivity and Easily manufactured Durable to withstand the design load and Convenient for fabrication Test at independent international test agent - ILAC (International Laboratory Accreditation Cooperation) - KOLAS (Korea Laboratory Accreditation Scheme). etc. Korea Rail Network Authority

17. Alloy melting Process of Contact wire (trial manufacture) Major accomplishment of development Korea Rail Network Authority Raw materials Adding element (Cr, Zr, Mg, FeP.etc.) 1250 ℃ Molten material treatment castingBillet Extrudable material (28mmΦ) Wire drawing (150mm 2 ) Cu-Mg-Fe-P trial manufacture Tension test

18. Key point Major accomplishment of development Test equipment to prove and verify the core parts independently was developed. Performance tests of trial manufactured core parts. Korea Rail Network Authority Wt.% Mg 0.0 83 0.6 49 Tensile Strength (MPa) Conductivity (IACS %) Conducti vity Tensile Strength 0.40~0.45 wt.% Mg

19. 3 step of test Major accomplishment of development Test track has been installed at KRRI. - verify the static & dynamic characteristics of catenary system & rolling stock Korea Rail Network Authority The speed increase test on 2 nd phase of Gyeongbu high speed rail. - 2 days per week for a month from Nov 29 till Feb 3, 2013 A test bed installation on Honam high speed rail.

20. Speed increase test Major accomplishment of development Increasing the speed from 350km/h to 400km/h by 10km/h interval. The max and min contact force (UIC code). Video monitoring. Korea Rail Network Authority

22. Conclusion Korea Rail Network Authority Full scale performance test - Verify the system stability and dynamic characteristics of developed material - From March 2014 on Honam high speed rail The data on R&D to be integrated in database Enhance the competitiveness with core components so as to introduce our state-of- the-art catenary system to the global market. Establishing the design & construction guideline for 400km/h catenary system Providing a milestone in independently developing a 400km/h catenary system.
