To ensure the safety of train operation, signalling equipment is installed along railway lines. For the maintenance of this equipment, a dedicated train called an "electric testing car" has been used. But this train is operated on the individual sections only twice a year and requires skill to analyze the collected data. Furthermore, the organizations of maintenance and surrounding environment are increasingly becoming difficult for railway companies in recent years. So we have developed a compact maintenance system that can be mounted on a commercial train and analyze data easily. In this paper, we explain the method of measuring signalling equipment, function of this system, and the results of field test.
