A train communication system is provided for enabling communications between wayside hubs and trains operating on a track. Each wayside hub includes a block processor and at least one hub radio, with the block processor and hub radio connected via a first network. The wayside hubs are interconnected through a second network. Each train includes a train radio connected to a train control system. The block processor transmits information to the train control systems via the hub radio. If a hub includes more than one hub radio, one is selected to act as a master hub to coordinate reception and transmission of messages between the block processor and the train radios within radio range of the hub radios. Synchronization information is exchanged between an upcoming hub and a current hub for a train upon determination that the train is approaching a boundary between the hubs.
A train communication system for providing communications to one or more trains operating on a track, the system comprising:
A method for providing synchronization information for a train approaching a boundary between two hubs, each hub comprising a block processor and a hub radio interconnected via a first network, the hubs interconnected to one another via a second network, the train being disposed on a track for movement thereon and comprising a train radio connected to a train control system, each block processor within radio range of the train radio being configured to transmit information to the train control system, the method comprising:
A method for obtaining synchronization information for a train approaching a boundary between two hubs, each hub comprising a block processor and a hub radio interconnected via a first network, the hubs interconnected to one another via a second network, the train being disposed on a track for movement thereon and comprising a train radio connected to a train control system, each block processor within radio range of the train radio being configured to transmit information to the train control system, the method comprising:
