It is well known that the railway network and infrastructure is sensitive to disturbances caused by climate changes. Hot days can cause rail buckling, thunder storm causes signalling failures, cold can lead to rail breakage, snow and wind can cause disruption of services and train delays. In short climate has considerable impact on the reliability and availability of railway system. The result from the study shows that occurrences and types of failures can be systematically linked and related to prevalent weather conditions, geographical location (near water, up in the mountain) of infrastructures, etc
