Excited to announce that TRAIN PhD student Diwen “Steven” Shi and Prof. Dick have recently published a new research paper in the Transportation Research Record academic journal! This paper examines how the diesel fuel saved by adding a Battery Electric Locomotive (BEL) to a freight train consist varies according to route topography, train weight, train resistance, battery storage capacity, and the efficiency of the traction battery system. The paper also examines the relative costs and benefits of different BEL implementation strategies to identify pareto-optimum combinations of BEL battery size and charging rate across each study corridor. To maximize return on BEL investment, it is critical to size BEL battery capacity to the unique energy characteristics of each route, and implement an appropriate terminal charging strategy to complement regenerative braking energy captured along the route. The paper was completed in collaboration with Mike Copley, who started this research when he was one of Prof. Dick’s MS students at UIUC.
