ABSTRACT:
A method of testing electrical continuity and so forth of distributing cables which are rigged in a plurality of mutually coupled vehicles of an electric, diesel or steam railroad train for electrically connecting monitored apparatus in the vehicles to monitors installed for watching and checking such monitored apparatus. The method comprises a first step of connecting at least one display means in common to the monitors installed in the train vehicles, a second step of disconnecting a connector from each distributing cable adjacent to the monitored apparatus and connecting the connector to a tester, a third step of feeding from the tester to each of the monitors a testing signal electrically equivalent to the output signal of the monitored apparatus, and a fourth step of displaying the information, which corresponds to the state of the distributing cable, on the display means via the monitor, thereby testing the cable with respect to the presence or absence of any abnormality such as breaking or deterioration.
