1. A method for computing car switching solutions in a railway switch yard having a plurality of classification tracks, a switch and a switching queue containing a plurality of cars to be sequentially switched by the switch to respective ones of the classification tracks, said method comprising:

  • a) providing a data processing apparatus having an output, the data processing apparatus being programmed with software to compute car switching solutions;

    b) iteratively computing with the software executed by the data processing apparatus a plurality of car switching solution for at least one car in the switching queue as the car progresses through the switching queue toward the switch, the computation of a car switching solution including a selection of a classification track among the plurality of the classification tracks in which the car is to be switched;

    c) releasing at the output of the data processing apparatus data conveying at least one of the computed switching solutions.
