National Railway Channel Forms File

The Shapefile format is intended for Geographic Information Systems (GIS). It contains all information related to the geometry of the objects described. It consists of three files with the same name, with the extensions SHP, DBF (attributes), SHX (geometry index) and PRJ (data projection system). The file contains all the tracks of the national railway network. A line section is a physically continuous part of a line, bounded by two end nodes (origin and end) of line section, and having a consistent tracking system. When there is discontinuity, the line is cut into several sections, with an increasing row. The accuracy of the track shapefile is metric: high-scale use (1/1000 to 1/5000) The values of the track type column are as follows: VPL = Main Lines; VPA = Main Paths Other; Vs = Service path This game publishes the database data at the end of 2018.
