Abstract

Devices, systems and methods are provided for updating one or more components of a transit system. A wireless communications connection is established between each train in a transit system with at least one master control station. Each car in a train is communicatively connected using a train'"'"'s consists and/or a local area network, which may include a wireless network. Positional information regarding each train may be communicated to the master control station and packages of information responsive to present or future scheduling, messaging, operating or other needs may be communicated to system components. Such packages may include, for example, scheduling updates and updated public address messages and may be designated for one or more terminals in one or more train cars, or otherwise. A master terminal may be configured to control intra-train communications and inter-train communications and positional reporting of a train to the master control station.
