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.
