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

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

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

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

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

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

Definition of development targets Target l 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 400 km/h level l Test bed for static and dynamic test in KRRI l Plan to install a 56 km-long test bed on Honam high speed rail l Test run for speed increase (on the 2 nd phase of Gyeongbu high speed rail) - verify the rolling stock performance and dynamic characteristics → Test bed in KRRI Korea Rail Network Authority

Major accomplishment of development De. CATS 400 l KRNA succeeded in independently developing a De. CATS 400 - applicable, convenient and appropriate to 400 km/h Catenary parameter l Check point - the plural number of designers to perform effective, rapid and precise design. <System Structure> <De. CATS 400 Mounting diagram on screen> <Data base Structure> Korea Rail Network Authority

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

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

Major accomplishment of development Key point l Test equipment to prove and verify the core parts independently was developed. l Performance tests of trial manufactured core parts. Conductivity (IACS %) Tensile Strength 0. 40~0. 45 wt. % Mg 0. 0 83 Wt. % Mg Conduct ivity 0. 6 49 Tensile Strength (MPa) <Fabrication of test equipment> <Various test results (Creep, Strength, Conductivity etc) > Korea Rail Network Authority

Major accomplishment of development 3 step of test l Test track has been installed at KRRI. - verify the static & dynamic characteristics of catenary system & rolling stock l 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 l. A test bed installation on Honam high speed rail. Korea Rail Network Authority

Major accomplishment of development Speed increase test l Increasing the speed from 350 km/h to 400 km/h by 10 km/h interval. l The max and min contact force (UIC code). l Video monitoring. <20 Hz Low pass Filter at 380 km/h> <Variation of mean contact force><Speed and current graph at 401㎞/h > <381 km/h Monitor screen> Korea Rail Network Authority

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