The invention discloses a test device for simulating train communication cable faults. The test device comprises a control unit and a cable connection controller; the cable connection controller comprises a data conversion module, a main control module and a relay module; the data conversion module is used for realizing data conversion between the control unit and the main control module; and the main control module is used for performing on-off control on the relay module according to a control instruction of the control unit so as to simulate cable joint connection loosening or cable core connection loosening or cable core fracture. The invention also discloses a test method, which comprises the following steps that: S01, the control unit sends a control instruction to the data conversion module, and the data conversion module converts the control instruction into data which can be received by the main control module; and S02, the main control module controls on-off of each relay in the relay module accordi
