especially for the traction in its daily operation. To implement energy saving programs and to studyrneconomical operation strategies, an energy estimated model is required. The models can be furtherrnextended to develop models and simulation for estimating power demand of train operation andrnminimizing energy consumption through different driving strategies.rnIn order to make analysis for train energy consumption and regenerative energy, this thesis workrnfocuses only Ayat to Torhiloch (East Wast) line of Addis Ababa Light Rail transit (AALRT).rnThe main targets of this research work is to analyze the effects of train overloading in energyrnconsumption of AALRT by comparing with different load conditions such as normal andrnmaximum load. During peak hour the number of passengers are high, overloading affects energyrnconsumption because it takes more energy to accelerate the train.rnMathematical modeling and simulation based analysis are presented to analyze the effects ofrnoverloading on train energy consumption. The models are formulated using train dynamics, trainrntractive effort and driving resistance which includes aerodynamic, gradient and rolling resistance.rnThe methodology to evaluate energy consumption is based on power and time.rnIn this research work Matlab/Simulink software is developed to analyze train energy consumptionrnand regenerative energy. The method that used to create the simulation of energy analysis atrndifferent track position such as level, uphill and downhill position.rnFinally, the Simulink result shows that, there is 11.05 % additional energy consumption is usedrnduring overloading when it is compared to normal train loading, 6.22 % used when it is comparedrnto maximum train loading condition. The result shows that during overloading the train needs highrnamount of energy consumption to accelerate.
