The major objective of this study is to proposal of measuring method and design for the testing curved railway in which the tilting train runs. In order to the speed-up of conventional lines that have many curve lines, there needs a improvement construction of substructure such as the straight or double track work and so on. But in this case, it needs to have a plenty of the cost and the period. Therefore, the tilting train which provides the high-speed service effectively in curve tracks was developed. Besides, the efficiency prediction and the linear synthesis of the existing conventional line for a tiling train service were examined on the preceding studies. So, in this paper we propose the measuring plan and the design of the improvement sections in the testing curved track which was decided as a results of material analysis and field research concerning the extension possibility of transition curves and the bearing of track due to the new developed train traveling. And we look forward to playing a decisive role as reference data on the improvement construction project for the commercial service of the tilting train.

The major objective of this study is to investigate the effective maintenance system for the infrastructure on the conventional lines in which the tilting train runs. In order to the speed-up of conventional lines that have many curve lines, there needs a improvement construction of substructure such as the straight or double track work and so on. But in this case, it needs to have a plenty of the cost and the period. Therefore, the tilting train which provides the high-speed service effectively in curve tracks was developed. Besides, the efficiency prediction and the linear fitness of the existing conventional lines for a tiling train service were examined on the preceding study which was the development of track system innovation technology for speed-up of them. So, in this paper we propose the more effective maintenance method than the existing it in order to securing the high reliability and safety classified by the infrastructure, in analyzing foreign materials and the maintenance as well as the inspection cycle concerning domestic infrastructures of the track and the catenary etc. on the railway. And we look forward to playing a decisive role as reference material for the effective improvement of the existing maintenance about the infra on the conventional lines for the commercial service of the tilting train.

In Gyeongbu high speed line, information transmission from wayside to rolling stocks are carried out via UM71 AF track circuits. And with the use of various frequencies, JES(Electrical Separation Joint) are used to conduct interference and blocking for adjacent track circuits. For such a non-insulated track circuit failures mainly occur in trackside, especially failures which are impossible to identify causes often occur. In this paper we analyze on turning unit BA of track circuits on which the failures occurred. For a relevant review, with the use of design values and measured values in the failure sites, we apply the maintenance method which SNCF has used

Locking sheet is to display the contents of interlocking equipment for safe train drive in stations. It is being used as a basic information for interlocking equipment and for route control condition and the discussion for train operation between related parties. In spite of importance of this, there was no other way except depending on the work by hands from each stage(drawing, examination, discussion, approval) due to non-existing any tool. It is written it takes 30days from drawing to approval by procedures. However, it is required over the days in real time due to argument of each party. Furthermore on drawing of locking sheet, special conditions applied in accordance with situations of each station occasionally are different depending on the person in charge. Therefore, it is urgent to make up Logic Tree to accept special conditions of all stations. Automation Program for Drawing and Examination of Locking Sheet is to improve inefficient interlocking operation which was operated by hands in accordance with custom as automated system. The target of this program is to minimize the processing time and potential errors by personal work and set up standards for Logic Tree of special condition.

The major objective of this study is to investigate the effective improvement plan for the curve sections in the conventional lines which the tilting train runs on. In order to the speed-up of conventional lines that have many curve lines, there needs a improvement construction of substructure such as the straight or double track work and so on. But in this case, it needs to have a plenty of the cost and the period. Therefore, the tilting train which provides the high-speed service effectively in curve tracks and is operating at abroad, was been studying to be suited to natural features. So, in this paper we investigate the improvement method at the sections only where need the extension of the transition curves, and the present status of them for the effective tiling train service using results which were examined on the preceding study which was the development of track system innovation technology for speed-up of them. And we look forward to playing a decisive role as reference material for the decision of the linear fitness in order to operate effectively on the conventional lines for the commercial service of the tilting train, on the basis of checking out the sufficient condition concerned in the track alignment and the velocity which are required in the railway construction rules and the design criteria.
