Abstract: A mini-computer based information system with on-line optimal route planning capability was developed to assist dispatchers on the complex northern portion of Southern Railway's Alabama Division. The routing plan is revised automatically as conditions change. Since implementation in September 1980, train delay has been more than 15 percent lower, reflecting annual savings of $316,000.The dispatching support system is now being expanded to all other Southern Railway operating divisions with $3,000,000 annual savings expected from reduced train delay.
