Reorganizing display of a railway timetable diagram

An apparatus for reorganizing display of a railway timetable diagram, the apparatus comprising:

• a memory storage device;
• a hardware processor operatively connected to said memory device and configured to:
• generate a relational graph by using a plurality of stations in the railway timetable diagram and correlations between the plurality of stations, a correlation between two stations existing when the two stations follow in succession along a path, the path comprising at least one of a train leg and a locomotive path;
• wherein to generate a relational graph, said hardware processor is further configured to:
• assign a higher value to correlation between two successive stations along a train leg;
• and assigning a lower value to correlation between two successive stations along a locomotive path;
• form sub-graphs based on paths in the railway timetable diagram;
• and consolidate the sub-graphs to form the relational graph, wherein said consolidating comprises:
• accumulating correlations between the same stations to obtain an overall impact of each path on correlations between stations;
• partition the relational graph according to a partition rule, wherein the partition rule reduces lines crossing at least one page and/or crossing at least one section in at least one page in a reorganized railway timetable diagram, wherein the lines represent associations between respective stations along a path in the reorganized railway timetable diagram;
• and
• display on an associated display device a reorganized railway timetable diagram based on a result of the partitioning.
