TRAIN MAINTENANCE AUTOMATING SYSTEM

Document Type and Number:

WIPO Patent Application WO/2002/034602

Kind Code:

A1

Abstract:

A train maintenance automating system which performs the work on train maintenance without human intervention. The train maintenance automating system comprises a refuse reservoir (10), a sewage tank (20), a water tank (30), and expanders (41, 42, 51, 61). With this automating system, when the train stops, the expanders (41, 42, 51, 61) are extended to raise connectors (45, 54, 64) toward the vehicle body for connection to the refuse reservoir (10), sewage tank (20), and water tank (30). In this automating system, discharge of refuse, withdrawal of sewage, and feeding of water are automatically effected. And upon completion of these operations, the expanders (41, 42, 51, 61) are contracted to store connectors (44, 45, 54, 55, 64, 65) in standby locations (48, 58). Therefore, use of this train maintenance automating system allows train maintenance to be effected automatically without human intervention.
