Abstract
A wireless train control network is adapted for forwarding data between a remote radio in an EOT unit and remote radio at the head of train using the base stations of the wireless train control network. A base station's current table of base station radios and remote radios that it hears or has a connection is distributed to neighboring base stations by a routing information exchange application. Tables are sent to and received from the application using a messaging service of the wireless train control network. A base station builds from the tables of neighboring base stations a route to a remote radio to which it is not connected, and forwards wireless data packets received for it by transmitting it to another base station radio.
