  • System and method for computing rail car switching sequence in a switchyard
    Publication number: 20080119973
    Abstract: As embodied and broadly described herein the invention includes a system for computing a preferred sequence in which cars in a switching queue of a railway switchyard are to be sequentially switched to classification tracks. The system has a processing entity for determining within a given set of cars at least two possible sequences in which the cars in the set can be switched and applying logic rules for identifying among the sequences a preferred sequence. The system also has an output for releasing data describing the preferred sequence.
