Abstract:
1. In a train dispatching system for controlling the movement of plural trains over plural track resources, the plural track resources being defined by domain data, a method of modifying the domain data comprising: (a) developing a first change set of intended modifications to the domain data, wherein the domain data defines the physical assets and devices that make up the rail network over which the plural trains travel, (b) developing a second change set of intended modifications to the domain data which reverses the modifications made by the first change set, (c) implementing the first change set to a domain data baseline in real-time while the dispatch system remains online and operational to users of the dispatching system during implementation of the modification to the domain data, including (d) evaluating the operational implementation of the first change set in real-time against a predetermined criteria; and (e) implementing the second change set in real time if the evaluation of the first change set does not satisfy the predetermined criteria to return the domain data to the domain data baseline.
