  • Publication number: 20030063111
    Abstract: A method and system for computing demurrage charges for a private railway site is provided. Information is delivered to a user for prompting him to enter demurrage charge computation parameters. The user enters the demurrage charge computation parameters via a computer interface. In response to the user providing the demurrage charge computation parameters, a database of railcar events is searched based on the demurrage charge computation parameters to derive a set of railcar entries. A charge policy is applied to the set of railcar entries to generate at least one data element indicative of a demurrage charge. The demurrage charge is then displayed to the user.
