The invention relates to a portable railway fault diagnosis device and a diagnosis method thereof, and belongs to the technical field of rail transit. The device comprises a protection box, and an analog load module, an acquisition test module, a CPU processor module and a diagnosis output module which are arranged in the protection box, the analog load module comprises a change-over switch and six branch circuits corresponding to the change-over switch, so that six simulation load circuits are formed. The six branch circuits comprise resistors R1-R6, capacitors C1-C2 and inductance coils L1-L2; and the device is suitable for processing and analysis of a railway electric service field work area under the condition that signal equipment faults occur, and fault properties are judged rapidly and accurately, the fault range is narrowed, and fault time delay is compressed by testing the simulation load at the signal machine room distribution board. The device can complete fault diagnosis and parameter test of 25Hz phase-sensitive track circuits and annunciator circuits of different systems.
