Abstract
A method of locating train events on a railway network is provided. The method includes the steps of: providing a reference point database which specifies locations of reference points on the network, the reference points being of different types, and the reference point database further specifying the respective type of each reference point; providing a relationship database which relates different train events to respective reference point types, for each combination of a train event and a related reference point type, the relationship database specifying a distance threshold criterion for the reference point type relative to a location of the event, and a reference point adjustment vector which specifies a distance from a reference point in a given direction on the network; receiving an event report for a train operated on the network, the report identifying a train event and imputing a location of the event on the network; comparing the event report with the reference point database and the relationship database to identify a reference point on the network which is of a type related in the relationship database to the train event of the event report, and which has a location on the network relative to the imputed location which satisfies the respective distance threshold criterion; and specifying the location of the train event of the event report to be the location of the identified reference point adjusted by the respective reference point adjustment vector.
