In this era of expanding energy costs and decreasing supplies of non-renewable energy sources, it has become
necessary to set up renewable energy based local power sources. This paper describes the use of piezoelectric materials in order
to harvest energy from vibrations of railway track for generating and accumulating the energy. Railway locomotive and coaches
produce high vibration due to heavy load during running time. The vibration is captured by using piezoelectric crystals. This
idea is also applicable to some large vibration sources which can find from nature. The energy so produced is stored in a battery
which is further used for other applications
