A group of people responsible for identifying which trains should move through which corridors, and at what speed, as well as what trains must move to a siding to let another pass. The dispatchers control an extensive system of electronic signals that act as stoplights to further insure operating safety.

Optional background processes, present only when a multi-threaded server configuration is used. At least one dispatcher process is created for every communication protocol in use (D000, . . ., Dnnn). Each dispatcher process is responsible for routing requests from connected user processes to available shared server processes and returning the responses back to the appropriate user processes.
