Office Equipment
In the office where dispatch and control is performed, a system provides a visual indication of the current status of communications with all locomotives as well as a close approximation of where each locomotive is currently located along the track.
In the event that maintenance is needed along any section of the track, before a work crew is dispatched or before a work crew is granted authority to proceed, a temporary speed restriction (TSR) is created in the office computer systems. After a series of verifications and procedures, the TSR is presented to the ACSES office system.
When a locomotive issues a query for TSRs for a given region, the WCM conveys the request for information to the office system via TCP/IP and the response is conveyed back to the locomotive which updates its local database with any restrictions.
