Abstract
Abstract A method of optimizing train operation includes determining conditions of location, track profile and train forces of the train. Next, a set of preliminary train restraint operating parameters are determined from the determined conditions. Also, at least one of a set of preliminary train optimizable operating parameters to minimize train forces, to maximize fuel efficiency and to minimize time to destination is determined. The determined set of preliminary train operating parameters are weighted and combined. Optimized train operating parameters are determined from the weighted and combined preliminary train operating parameters. Engineering train and access is also performed.
