Securing of transport reliability is one of the important missions of the railway company. We have enforced a countermeasure from both sides of hardware and software till now. But, we must have to plan for the stability improvement of the transport from the various points of view to get more trust from the customers. So, we developed the system that other devices mutual backup the device which broke down. JR east is developing the Advanced Commuter Train ("AC Train") with the aim of achieving concepts for the commuter and suburban trains of the 21st century. One of development concepts of the AC train is "improvement of transport reliability". It feature mutual backup of control equipment including safety equipment (ATS-P : Automatic Train Stop with pattern), door operating unit and brake demand operating device. It is the device that gives great transportation influence when these devices cause trouble. In addition, it is plural carried devices in a train. Information technology is required, but a recent vehicle is equipped with control information system in order to develop a backup system. JR east develops TIMS (Train Information Management System) as a vehicle information control unit already, and a newer system is equipped AC Train. We call a vehicle information control unit of AC Train AIMS (Advanced train Information Management System), and there is high-speed inside of car LAN (Local Area Network) than TIMS. ATS-P used LAN of AIMS and did it with the system that a device of front and back of a train backed up mutually. A door is equipped with a lot by a train, but AIMS understand it which door device broke down by monitoring information and can send order information to a door device to back up. Brake control unit makes control to be different every device every vehicle in order to be different in load. Because load is different, we establish a control unit every chassis every chassis in AC Train adopting articulated system in particular. In this way, as the system that the device, which was different in movement, backed up mutually, we developed a backup system of brakes demand operating device. In development of this time, the basic function of each backup system by practical use of an information transmission device was able to confirm that we worked by a conventional examination well. We are to do examination about confirmation of the durability by run examinations or miniaturization of a device in future.
