Braking is a very complex process in overall railway assembly, braking system has a great importance and contribution towards the safety. During braking a number of phenomenon occurred like mechanical, thermal, electrical etc. which led to the high forces act on the brake blocks of railway results in thermal cracks, reduced life of blocks. It is estimated that a minimum of 60 brake shoes or brake blocks are used in the railway wagons which have to be changed within a month. In our study, author investigated and analyzed the braking tribology characteristics i.e. to determine the wear rate and coefficient of friction at a constant frequency at different temperature by keeping the stroke length constant. The experiment reveals the rate of wear and coefficient of friction varying at ambient and in summers during to continuous exposure of brake block for a fixed distance moved. The experiment is performed on the liner reciprocating tribometer by using stainless steel pin without any aid of lubricating material.
