Abstract

A train network management system for a train having a locomotive and railcars, including a node computer on the railcar and communicating with a high-speed network device for receiving and transmitting data over a high-speed network, and a locomotive computer on the locomotive and communicating with a high-speed network device for receiving and transmitting data over the high-speed network, where a communication path is generated between at least two high-speed network devices of the railcars and the high-speed network device of the locomotive, such that high-speed data communication is provided between the high-speed network devices of the railcars and the locomotive. A railcar network unit is also disclosed.

First claim
