  • Patent number: 6931995
    Abstract: An automation system for train maintenance that performs operations related to train maintenance without human intervention is provided. The automation system for train maintenance comprises a refuse reservoir (10), a sewage tank (20), a water tank (30), and expanders (41, 42, 51, 61). In this automation system, when a railway vehicle is parked, the expanders (41, 42, 51, 61) are expanded to lift connectors (45, 54, 64) toward the railway vehicle for connection to the refuse reservoir (10), sewage tank (20), and water tank (30). In this automation system, discharge of refuse, removal of sewage, and feeding of water are automatically performed. Upon completion of these operations, the expanders (41, 42, 51, 61) are contracted so that the connectors (44, 45, 54, 55, 64, 65) are stored in waiting locations (48, 58). Therefore, use of this automation system for train maintenance allows automatic train maintenance without human intervention.
