Smart System to Prevent Axle Seizure in Rolling Stocks (Trains)

Axle seizure is one of the major problems faced by the railways. The two main factors leading to axle seizure are bearing overheating and brake binding. This study, mainly concentrates on determining the exact location of the fault (i. e. bearing overheating or brake binding (Air brakes). A system is devised to detect and rectify the above mentioned faults. It consists of temperature sensors, pressure switches, GPS unit and solenoid valve to overcome the problem of detention of trains which results in loss of punctuality and to prevent damage to the profile and the wheels.
