Rail-Scout
(This concept was originally
developed
in 2001 by H.Ben Brown and Gregg
Podnar)
Whitepaper from 2005 (most recent)
Description from 2002
Initial description from November 2001:
In light of recent acts of terrorism, the railroads and trains
must be viewed as a target for low-effort / high-impact attacks.
We propose to apply current technologies to produce a system which
addresses three key areas:
1. Derailment
2. Positive train separation / collision avoidance
3. Grade crossings
RailScout is a small vehicle which runs ahead of the train, remotely
driven by the motorman. Adjusting the front-running distance to
exceed the current stopping distance of the train allows the train to
stop before encountering a hazardous situation.
RailScout provides a means for the motorman to see the track ahead and
monitor a number of aspects of track geometry. Automatic obstacle
detection enhances collision avoidance. At grade crossings, RailScout
can provide additional audible and visual warning signals, and occupy
the crossing until the train approaches.
By combining current sensors, telecommunication, and robotics
technology, the safety of personnel, passengers, and other vehicles
can be greatly improved.
