Abstract—There are different types of coaches which are used in Indian Railways. Some of the Coaches are used for carrying passengers over long distances. In order to have smooth journey these coaches are fitted with Air Spring Bellows which absorbs the shocks and jerks which are created due to undulation of track and many other reasons. Since Air spring bellows are filled with compressed air some mechanism is required to detect and apply the brakes in the train in case of any such failure. There are many such designs of FIBA which detects the Failure of Air Spring and apply the Brakes. Most of these designs involve a large number of parts and are comparatively bulkier in size. These reasons have made it a very expensive device. In order to make it more affordable there is need of doing further research on it so that it can be made economical with out compromising on its functionality and can be used on all kind of passenger trains. This research paper is an attempt in this direction.
