Computer-aided model construction and database design of railway yard information

Railway yard is the basic composition unit of railways, therefore, the efficiency and quality of railway yard design have a crucial effect on the construction and operation of railways. Plane design is the basis and core of railway yard design, consequently, it is significant to research plane design of railway yard. In this study, through analysis and summary of the research status as well as integrated application of computer technology and railway yard plane design methods, we researched and developed railway yard plane design system based on AutoCAD platform. According to the characteristics of railway yard plane design, we constructed the information model based on which we established specialized database, with the information data organized and managed efficiently; moreover, we put forward methods of constructing geometric models of the plane equipment, meanwhile, we did a focused research on associated design of yard equipment and preliminarily realized linkage design of planar yards.
