East Japan Railway Co. has developed a 100Mbps (Megabit per second) -Ethernet-based TCN (Train Communication Network), called the "INTEROS" (INtegrated Train communication networks for Evolvable Railway Operating System). The INTEROS is characterized by large capacity communications among railroad cars and between various on-board devices and ground systems. The INTEROS' main function is command transmission from a driver to on-board devices such as propulsion systems and brake control devices. In addition, the INTEROS deals with various assistance functions for drivers and crews, data transmission function for passenger services and remote maintenance using status data from on-board devices. In the system will send on-board bulk data to wayside systems at maintenance depots and operation centers by using general-purpose wireless communication such as Worldwide Interoperability for Microwave Access (the WiMAX). The INTEROS prototype was loaded on a test car for its functional checks. All the functions were successfully checked in the running tests. Development results were installed in E235 series railroad cars that will run on the Yamanote Line in Tokyo.
