The invention provides a method for diagnosing the faults of a city rail train brake system. The method utilizing train speed signals in a train communication network (TCN), train load signals and force measuring coupling gears among carriages includes: building a dynamic model and a train braking force residual error model, acquiring the observation gain and weight matrix of the standard residual error signals of the brake system of a whole train so as to obtain the observation gain and weight matrix of each carriage, and allowing a residual error generator to diagnose the faults of brake sub-systems through a calibration threshold.
