Efficient Deployment of Dual Locomotives in Regional Freight Rail Transport

The present article focuses on the efficient deployment of dual locomotives in regional rail freight transport considering quantification traction energy and savings. In first part article, a categorization locomotives, according to their power output electric alternative (and ratio both outputs) is proposed. potential chosen Central European conditions (a sub-network Czech railway network around mainlines electrified with AC) verified by calculation consumption model train (with two examples locomotives). addition non-stop running through entire line, stop following acceleration) each intermediate station calculated, for particular direction. Then, appropriate paths passing passenger trains saving are results supplemented sensitivity analysis form variable numbers loaded wagons, help iPLAN/FBS timetabling software. limitations maximum length or gross mass train. Finally, conclusions obtained from computational evaluated recommendations planning targeted improvements infrastructure formulated.
