Patent Images
1. ) An apparatus 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 apparatus comprising:
- a) a data processing device having a CPU, the data processing device being programmed with software for execution by the CPU to compute car switching solutions;
b) the data processing device iteratively computing with the software executed by the CPU a plurality of car switching solutions 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) an output in communication with the data processing device for outputting data conveying at least one of the computed switching solutions.

Abstract
A system for computing car switching solutions in a railway switch yard. The system is computer based and has an input for receiving data conveying information about one or more arrival trains arriving at the switch yard and data conveying information about departure trains to depart the switch yard. A processing entity processes the data and computes car switching solutions for the railcars.
