Abstract: Braking system is an essential feature for halting and stopping the railway vehicle within the minimum time. This paper offers a discussion on the various braking systems used in railroad vehicles. This paper also looks at electrodynamics and electromagnetic train braking, which is especially important in high-speed trains. A train that moves requires energy, known as kinetic energy that needs to be removed from the train to cause it to stop. The simplest way to do that is to turn the kinetic energy into heat energy. Normally the conversion is achieved by adding a contact substance on the spinning wheels or on the disks connected to the axles. The substance creates friction and the kinetic energy is converted into heat energy. The wheels slow down and the train ends up halting. The material used to brake is usually in block or pad shape. The vast majority of trains around the world are fitted with braking systems that use compressed air as the force to drive the blocks on to wheels or pads to discs.
