Saction of line

Section of line made up of one or more running tracks (see A.I-01.1) between two adjacent operational points (see A.I-13). The length of a section of line is measured in the middle of the section, from centre to centre of operational points at the start and end of the section of line. If the boundary of the rail network falls in open track, the length of the section is measured up to that point. The section situated between a station approach and the join to the main line of two or more lines, which is used by all trains in either direction over these lines, is only counted once. However, if for one or more of these lines, tracks are normally allocated, the length of these lines is counted separately.
