In this study, as a part of research which is to make 50kg NSI turnout of PC sleeper, the main objective of this study is the optimization of PC sleeper"s section, the number of PS tension wire. For this purpose, the finite element analysis was conducted to evaluate the serviceability and the safety of NSI PC sleeper developed. Analytical results showed that PC sleeper adapted in this study satisfied not only serviceability criterion but also safety criterion.

In this study, as a part of research which is to make 50㎏ NSI PC sleeper Turnout, the main objective of this study are the development of the PC sleeper and the applications H-type guard, 1/40 cant in the turnout, the same position of the switch, incident angle=0, the same skelton. we completed development and laid 50㎏ NSI PC sleeper turnout at the Shintanjin station. Now we are inspecting the turnout in site every weeks.

Since KHSL 2nd phase was adapted as a main track design, the interests of concrete slab track system have been gradually increased in the division of rail track engineering and many engineering companies have been trying to adapt a concrete slab track system at this moment. Advantages of this system proved in advanced country, japan and Germany etc. are excellent maintenance, track stability and increasing of buckling resistance This developed turnout is same with the KHSR 1st phase"s design and applications rules, components and signaling system since it observes KTX specification. Comparing it with the former turnout, High-elasticity pad, lubrication-free roller slide plate and Rheda2000 PC sleeper are only different. The purpose of this study is the development of high speed turnout on concrete slab track and its application on site. Now these studies are going to show the verification and confidence about the interface between ballast-track and concrete slab track by finding and solving the possible problems when it is installed on site and to make these turnouts applied perfectly and completely on concrete slab track. Its first trial construction in korea had been successfully completed at Sangju-station on July 20th ,2007 thanks to KORAIL and KR. Hereunder Sampyo E&C trys to introduce all of turnout technologies on concrete slab track system with Rheda 2000 sleeper.
