A method is provided for operating a train or rail vehicle along a railway which is logically divided into segments, and includes at least one control point presenting at least two possible paths that are exclusive of each other, each path including one or more segments. The method includes: (a) controlling the rail vehicle as it travels along the railway by reference to a one-dimensional representation of the segments prior to the control point; (b) determining which segment located immediately past the control point is to be occupied by the rail vehicle; (c) after the rail vehicle has traveled past the at least one control point, verifying which segment was occupied; (d) interlocking the occupied segment; (e) passing segment information to the rail vehicle; and (f) controlling the rail vehicle as it travels along the railway in reference to a one-dimensional representation of the segments past the control point.
