From_Wayside_Equipment

This data flow represents information received by HRI from railroad maintained and operated wayside interface equipment (track circuits, gate controllers, local connections to centralized sites via railroad communications networks, etc.). This is assumed to be a real-time, or near real-time interface capable of providing direct communications with (or otherwise detecting) approaching trains. This data flow consists of the following data items each of which is defined in its own DDE:

fwe-approaching_train_announcement
+ fwe-train_data
+ fwe-wayside_equipment_status
