Abstract
A train speed profiling system for use in connection with a train management system that can generate a virtual profile of a predetermined route having an estimated time of arrival at a destination based on data specific to the route and the actual train that will travel on the route. The virtual profile may be adjusted for any acceleration and any deceleration required by the train, and then optimized for reduced fuel consumption by reducing braking effort and improving coasting opportunities over the route if the estimated time of arrival is earlier than a desired time of arrival. The virtual profile may further be conformed so that the estimate time of arrival matches the desired time of arrival within a narrow threshold.
