Pantograph, which collects current from cartenary system, is one of the important parts of high-speed train. Kinematic analysis is one of the key technologies for pantograph design and includes joint trajectories, reaction forces, and the required moment of main shaft calculations. The kinematic analysis, however, is very complex and time-consuming process. In this study PC based pantograph kinematic analysis software using graphical user interface tool was developed for the easy evaluations of kinematic characteristics necessary in pantograph design process.

Pantograph, which collects current from cartenary system, is one of important parts of high-speed train. Kinematic analysis is basic component of pantograph design. But kinematic analysis is very complex and time-consuming. Therefore numerical calculation of pantograph kinematics is necessary. In this study, pantograph kinematic analysis software was developed and relationship between kinematic parameters and pantograph performance was investigated. The software and relationship between kinematic parameters and pantograph performance are helpful to pantograph designers

This paper studied technical investigation of effective operation and methodology for technical combination in south and north korea. For harmonious transportation on railroad system, the system of trans-korea railroad investigated on each part(system, Rolling stock, Cartenary ＆ Electricity, Signal and Track etc). Though it isn't show many difference on railroad system, we can show some difference on rolling stock, track and signaling system. For the effective and competitive operation on south and north korea, Many problem investigated and proposed alternative proposal for selecting of rolling stock(diesel or electric), track and signaling improving for speed-up and compatible system at AC and DC system.
