Abstract
A system includes an interface through which actual train operating data can be transferred from a recording medium, such as a magnetic tape, into a train simulator. The date contents of the magnetic tape are generated from real-time data obtained on-board an operating locomotive. For entering additional data, the interface switches a manual data entry terminal to the train simulator in response to a control signal provided by the train simulator. A method incorporating this system simulates train responses to the actual train operating data.
