Abstract: Crash buffers are widely used in railway coaches to ensure that during sudden acceleration or deceleration they provide sufficient reduction in vibration and shock absorption. During exigencies like accidents crash buffers helps in minimizing the physical damage to coaches and human life by absorbing the shock energy. In the present work, experimental and Finite Element Analysis [FEA] had been performed on the standard railway side (crash) buffers by using the deformation element as a single component along with various design modifications in buffer casing. The four proposed modifications of conventional buffer casing were termed as S1, S2, S3 and S4. In the planned deformation of the modified buffer casings (deformation travel), it has been observed that there is around 10-20% rise in energy absorption than the conventional buffers with standard spring action. Out of four design modifications the S4 buffer has shown the maximum load and crash energy bearing ability. Energy absorption for S4 buffer increased by twice as compare to S1 samples. Results obtained exhibits the effectiveness of prototype crash buffer with modified geometry over the conventional buffers useful in minimizing the damage to railway coaches in case of accidents to a greater extent
