Abstract
A distributed control system for a track network includes a local controller connected to a plurality of switch machines and a central office. The local controller receives from each switch machine a switch position signal and outputs to at least one switch machine a switch control signal related to a desired state of a track switch associated with the at least one switch machine in one of a plurality of positions. The local controller further outputs to the central office a first communication signal including switch position data corresponding to the switch position signal output by the at least one switch machine and receives from the central office, as a function of the first communication signal and a desired movement of one or more vehicles on the track network, a second communication signal which includes switch control data corresponding to the switch control data output to the at least one switch machine.
