1. A method of operating a railway having a plurality of trains for movement along predetermined track layout, the method comprising:

  • (a) determining a movement plan by which the trains move along the layout using a constraint based analysis based upon strategic schedule constraints and an optimization of the costs of the movement plan, said determining comprising an evaluation of the effects of physical track parameters on the movement of the trains, including(i) determining a schedule using statistical data relating to train movement; and

    (ii) refining the schedule using simulation of the motion of the trains by advancing the time and position of the trains along the track layout as a function of the track parameters;

    (b) communicating the determined movement plan to the trains;

    (c) determining train throttle and brake settings of a respective train for implementing the plan; and

    (d) controlling said trains to move along the layout in accordance with said determined movement plan with said settings.
