Overview ofKorea’s High Speed Rail development
Korea Rail Network Authority
April. 2004.
- The 1st phase of 300km/h Gyeongbu high speed
rail (Seoul ~ Dongdaegu)
Nov. 2010.
- The 2nd 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 ofKorea’s High Speed Rail development
Korea Rail Network Authority
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)

Pantograph modeling
400km/h Catenary system requires : - tension increasing → contact wire & messenger wire changeCore 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.

→ 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 levelTest 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 2nd phase of Gyeongbu high speed rail)
- verify the rolling stock performance and dynamic characteristics
