The use of train performance simulations in the development of locomotive concepts

The design specification for the procurement of a locomotive has transitioned over the last 15 years from being a highly specific document detailing engine power, tractive effort and other performance measures to typically being a performance specification detailing the train size or the tonnage to be hauled per year and the route over which the train is to be operated. A performance specification provides the locomotive supplier with the freedom to offer a concept best suited to the operations based on their knowledge of the latest product developments. The development of a locomotive concept to meet a performance specification requires the consideration of the available components or building blocks (such as engines, alternators and traction motors), required trailing loads, route profiles and mandated sectional running times. Train Performance Simulations can be used as an effective tool to analyse the performance specification and translate it into a detailed requirements list including horsepower, tractive effort and fuel capacity while providing the engineer with a tool to examine various locomotive and train configurations available. This paper will review United Group Rail’s use of simulation techniques in the development of locomotive concepts, considering the process used, the benefits of the information developed, both to the locomotive concept and to the potential customer through maintenance and life cycle costing models, and examine the limitations of the method.
