The invention relates to the technical field of rail equipment, in particular to a train fault comprehensive diagnosis instrument and a diagnosis system. The train fault comprehensive diagnostic instrument comprises a shell, and a rotating speed processing board, a derailment monitoring analog board, a derailment monitoring digital board, an alarm cascade board, an analog board, a digital board, a bottom board and a power board which are arranged in the shell, the rotating speed processing board converts a vehicle rotating speed signal into a rotating speed pulse signal; the derailment monitoring analog board is connected with a composite sensor at the position of a vehicle axle box, and the derailment monitoring digital board processes a composite sensor signal and a rotating speed pulse signal after resonance demodulation to realize derailment monitoring diagnosis of a vehicle; the alarm cascade plate is used for transmission and interaction of extension derailment alarm signals; the analog board is connected with a vibration signal acquisition assembly at the position of a vehicle gearbox, and the digital board is used for derailment monitoring of signals processed by operational amplification of the analog board, signals of the acquisition assembly after resonance demodulation and processing of rotating speed pulse signals, so that monitoring and diagnosis of walking faults of a vehicle are achieved.
