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 thank those who were good enough to say something pleasant about the incoming administration, for I am glad to get it now. I heard of the man who went into office with a majority and went out with unanimity.”
—William Howard Taft (1857–1930)
“Biological possibility and desire are not the same as biological need. Women have childbearing equipment. For them to choose not to use the equipment is no more blocking what is instinctive than it is for a man who, muscles or no, chooses not to be a weightlifter.”
—Betty Rollin (b. 1936)
