Williams Controls Subsidiary and Nestor Traffic Systems to Provide Advanced Warning Alert System at Rail Crossings

    PORTLAND, Ore., Aug. 31 Williams Controls, Inc.
announced that its wholly owned subsidiary, GeoFocus, Inc., and
Nestor Traffic Systems, Inc., an affiliate of Nestor, Inc.
(OTC Bulletin Board: NEST) have signed a teaming agreement to provide an
advanced railroad grade crossing warning system for enhanced rail and traffic
safety.  Nestor Traffic Systems is an emerging leader in providing innovative,
video-based monitoring systems and services for traffic management and safety,
and GeoFocus is a rail industry leader in train vehicle location and
information management systems.
    The agreement combines each company's unique products into an innovative
rail crossing safety enhancement system called the Advanced Warning Alert for
Railroad Engineers (AWARE).  The system will utilize Nestor's video image
recognition and analysis technology, Rail CrossingGuard, installed at the
grade crossing, and GeoFocus' on-train Global Positioning System (GPS) based
train information management system, called TrainTrac(R), to detect a wide
variety of track obstructions and crossing gate failures and send warnings
directly to train operators as they approach the affected crossing.
    "We are pleased to partner with GeoFocus in the creation of AWARE," stated
David Fox, President and CEO of Nestor Traffic Systems.  "Combining our video-
based vehicle detection and their communications capabilities is a natural
fit.  Being able to alert an approaching train to a vehicle on the tracks is a
monumental advancement in rail crossing safety."
    "This teaming agreement with Nestor represents an important new initiative
for the diversification of our products while capitalizing on our leadership
in GPS-based products for the rail and transportation industries," stated
Williams Controls Chairman and CEO Thomas W. Itin.  "The overlay of the Nestor
technology is a natural extension of our TrainTrac product's ability to know
where a train is in relationship to grade crossings and to effectively use
Nestor's technology to greatly improve the awareness of the train operator and
safety of the train in relation to vehicles at the installed crossing.  The
relationship with Nestor is a marriage of industry product leaders and
represents a very strong commitment to rail safety that we believe is a win-
win situation for all concerned."
