Performance comparison between disc brakes and tread brakes for railway wagons
Background
Tread brakes is most commonly used braking system on wagons. Further, a variety of brake block materials can be used on these wagons depending on the operating conditions. These material are: cast iron, organic composite and sinter material. In heavy haul or high-speed freight trains, use of wagons with disc brakes is increasing. In addition, winter conditions might reduce the life of wheels in tread braking even further. There are trainsets that use wagons with tread brakes and wagons with disc brakes. Such trainsets can be utilized to make a direct comparison on performance between tread brakes and disc brakes.
Problem description, tasks, and goals
Life cycle costs for wagons are influenced by wheels and brake discs. This study can provide strong basis for deciding the utilization of wagons with optimal braking system to be used in trainsets. Goals: 1) To compare the wear data for wheels and discs 2) To study the types of damage that reduces the life of wheels and discs.
