Running train induces vibrations in railway tracks. If the track vibration could be minimized, the vibration level of base structure holding the track can be minimized. Thus we report an analysis to use viscoelastic damping material to reduce the vibration. We have derived the expression for the Figure of Merit (FOM) to minimize the transverse displacement of railway track considering as response variable. Also we have reported numeric to support the results.

The following major steps are involved in the reduction in vibration level of rail track,

Identification of source and characterization Specification of level for reduction in vibration Selection of appropriate method for reduction of vibration Preparation for analytical solution and design Practical Realization or hardware mechanization

In the the following report we have discussed the first four steps. The last step i.e. practical realization has not been done.
