| Abstract |
The “Intelligent Railroad Alignment Design Program (ei-Rail) developed in 2013 has been adopted in the planning and the evaluation/validation of design results of oversea railroad construction projects. Target countries of Korean railroad industries requiresthe operating speed increase with alignment improvement and the double tracking of prevailing single track railroads as well as new railroad construction. This study is to develop an additional module for double tracking project of prevailing single track railroads in the ei-Rail. The developed method is based on the geometrics of prevailing railroad, and the definition of planned project determines the project cost based on the unit cost by work type, and provides the draft design of double track. The module was validated with aoversea case. It is then expected for oversea railroad double tracking project more efficiently in planning and the evaluation of design results. |
