The air brake is the standard train brake used by railways all over the world. To test the braking system of single car a Rake test rig is used. It is based on the simple physical properties of compressed air. The Rake Test Rig performs the braking test at Twin Pipe Braking system of coaches. Rake Test Rig used has two pressure gauges that are Feed pipe gauge and Brake pipe gauge. The existing test rig used at workshop has number of conventional joints, complex construction and its weight. In this paper the improvement in rake test rig construction is implemented to overcome the existing problems and the brake testing procedure is also studied. The improved design and construction made the test rig more accurate than existing and problems were found to be completely resolved.

Testing procedure, Coach, Brake pipe, Feed pipe, Improved RTR.
