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.

Famous quotes containing the words office and/or equipment:
“I leave the governor’s office next week, and with it public life ... [which] has been on the whole a pleasant one. But for ten years and over my salaries have not equalled my expenses, and there has been a feeling of responsibility, a lack of independence, and a necessary neglect of my family and personal interests and comfort, which make the prospect of a change comfortable to think of.”
—Rutherford Birchard Hayes (1822–1893)
“Pop artists deal with the lowly trivia of possessions and equipment that the present generation is lugging along with it on its safari into the future.”
—J.G. (James Graham)
