One of the largest railway networks in the world with super-dense crush load on their EMU and MEMU stock running on suburban networks across various cities of India run on Sona Comstar's manufactured systems for their braking, coupling and suspension requirements. We have been manufacturing Electro-Pneumatic Brake Systems for more than three decades. These Brake Systems are in use on EMUs, MEMUs, and DEMUs in Indian Railways. Sona Comstar's EP Brake System has two distinct modes of operation. The primary mode of operation is electro-pneumatic application of the brakes throughout the train and the second mode of operation is the application of back-up brakes in case of electrical power failure in the system.
