Recently remote sensing technology is applied for construction planning and design areas by use of remote sensed satellite images according to engineering application technology in the various experimental tasks. In this study, it was applied for 3 dimensional terrain analysis and basic design by comparing with present railway and newly expanded double-tract railway route of forest sites on the new construction site of 15km at national railway lines, and then showed 3-D perspective images and fly simulation images to examine possibility of various application as terrain analysis modeling and running simulation at the corresponding course. As a result of its application, it gained the results not only improvement of present methods but also real various application possibilities.

The induced voltage on the telecommunication cable generated by nearby electric railway system may bring about telecommunication errors and safety accidents. In order to reduce the induced voltage and to achieve communication reliability, the effect of the shield cables and the recent double-track railway systems on the inductive interference should be investigated. This paper analyzes the parameters which seriously influence the induced voltage on the telecommunication cables which run parallel with a AT-fed electric railway line, and provides a simulation-based approach to estimate the amount of the induced voltage. Simulation results indicate that the induced noise voltage generated by a double-track railway decreases by 18 % compared to that generated by a single-track railway, showing the screening effect by nearby track. The induced noise voltages on the 50%-shielded cable and 15%-shielded cable decrease to 1/8 and 1/15 of the induced voltage on the non-shielded cable, respectively. A meaningful shield effect is achieved and the induced voltage is minimized by the double-track railway and the shielded cable.

The curved line in construction of railroad is inevitable. Also it needs a transition curve when the straight line connects to curved line. In this research, by establishing the reciprocal relations of inner, center and outer track, we will present the calculation method of construction-center line in normal double-track railroad which uses cubic parabolic type as a transition curve.
