BACKGROUND OF INVENTION: As we all know electricity is an important driver for industrial as well as agricultural growth of any country. We are also aware that it is a scarce resource in India. The rate of increase in demand is going up with each passing year. Therefore there is an urgent need to find newer and better ways for conservation of utilized energy. The present invention is an effort to aid in overcoming this problem. The present invention relates to an electric power generation system using rotational energy from moving train and converting it to electrical energy. In the present scenario, electricity is required for running a train. Consumption of electric power is very high. This system can be used in trains which run on diesel engine. When a train is in motion, the otherwise wasted rotational energy can be tapped by means of gears and shafts and converted into electric energy for industrial and domestic use.
