Patent ID: 8311688

Claim:
A method comprising: developing a first change set of intended modifications to domain data of a train dispatching system, wherein the domain data defines physical assets and devices that make up a rail network over which plural trains travel; developing a second change set of intended modifications to the domain data which reverses the modifications made by the first change set; implementing the first change set to a domain data baseline in real-time while the dispatching system remains online and operational to users of the dispatching system during implementation of the modification to the domain data, including: determining the domain data to be modified by the first change set; preventing the implementation of the first change set if the domain data to be modified is currently being accessed by the dispatching system; and notifying a user if the implementation of the first change set is prevented; evaluating the operational implementation of the first change set in real time against a predetermined criterion; and implementing the second change set in real time if the evaluation of the first change set does not satisfy the predetermined criterion to return the domain data to the domain data baseline.
