To remain competitive in the competition on the cargo market, railway undertakings need to execute operations with high efficiency. IT systems can contribute to determine the actual boundaries of the use of available production resources and operate optimally close to these bounds. Mathematical optimization and automation are key factors to realize this, e.g. in the field of Locomotive rotation planning. This contribution describes different approaches that have been implemented in the Locomotive Optimization System LOOP which has been developed by DXC Technology in close cooperation with Green Cargo – the largest rail cargo operator in Sweden.
