<h1>JMRI Dispatcher: AutoTrains</h1>
|
|
|
|
<h2>Introduction</h2>
|
|
|
|
<p>The <strong>AutoTrains</strong> pane allows the dispatcher to take control of an Auto
|
|
Active Train (an automatically running Active Train) from the <em>virtual dispatcher</em>
|
|
when required to solve a problem, and to restore automatic operation after the problem is
|
|
solved. Example problems requiring the dispatcher to intervene are derailment of the train,
|
|
or unexpected uncoupling of cars in a train. This window is also used to restart automatic
|
|
operation after suspending it for a human engineer to switch train cars or perform other
|
|
work.</p>
|
|
|
|
<p>When the first Auto Active Train is created in <strong><a href=
|
|
"Dispatcher.shtml">Dispatcher</a></strong>, an <strong>AutoTrains</strong> pane is opened
|
|
immediately to the right of the Dispatcher window. The pane may be moved to another location
|
|
if desired. An entry is added for each additional Auto Active Train as it is created. When an
|
|
Auto Active Train is terminated, its entry is removed from the <strong>AutoTrains</strong>
|
|
pane.</p>
|
|
|
|
<h2>Using the AutoTrains Window</h2>
|
|
|
|
<p>Below is an <strong>AutoTrains</strong> pane showing two Auto Active Trains, Amtrak 139
|
|
and GTW 6418. Entries are separated by a horizontal line.</p>
|
|
<img src="images/AutoTrainsA.png" alt="Auto train status" width="337" height="177">
|
|
<p>Each entry has a <strong>Stop</strong> button and a <strong>To Manual</strong> button. If
|
|
the dispatcher presses the <strong>Stop</strong> button, the Auto Active Train is immediately
|
|
stopped. The stopping is an emergency stop--no gradual reduction of speed. Clicking the
|
|
<strong>Stop All AutoTrains</strong> button at the bottom of the pane will issue an emergency
|
|
stop to all Auto Active Trains shown in the <strong>AutoTrains</strong> pane.
|
|
<strong>Stop</strong> buttons change to <strong>Resume</strong> buttons when trains are
|
|
stopped. Each stopped train must be restarted individually by clicking its
|
|
<strong>Resume</strong> button.</p>
|
|
|
|
<p>Once an AutoTrain has completed its run, the <strong>Stop</strong> button changes to
|
|
<strong>Restart</strong>. Pressing this causes the AutoTrain to begin running again.</p>
|
|
|
|
<p>If the dispatcher clicks the <strong>To Manual</strong> button for Amtrak 139, its line in
|
|
the pane changes to:</p>
|
|
<img src="images/AutoTrainsB.png" width="576" height="176" alt="Auto train manual mode">
|
|
<p>The <strong>Fw</strong> (Forward) and <strong>Rev</strong> (Reverse) radio buttons control
|
|
the train direction and the slider controls the train speed. The dispatcher can use these
|
|
controls to run the train and fix whatever problem is present. When the problem is remedied,
|
|
clicking the <strong>To Auto</strong> button will restore automatic operation of the
|
|
train.<br>
|
|
Note: Prior to clicking its <strong>To Auto</strong> button, the dispatcher should run the
|
|
train to the same location where it was when <strong>To Manual</strong> was clicked. This
|
|
assures smooth resumption of automatic operation.</p>
|
|
|
|
<h3>AutoTrains - Go to Manual Mode Action</h3>
|
|
|
|
<p>One of the user-selectable Transit <a href=
|
|
"../beantable/ViewSpecialActions.shtml">Actions</a> is <strong>Go to Manual
|
|
Mode</strong>.<br>
|
|
This Action supports running an Auto Active Train automatically to a work site, where a human
|
|
engineer takes over to perform operations (perhaps switching cars), after which automatic
|
|
running is continued following the same Transit. When the <strong>Go to Manual Mode</strong>
|
|
action is initiated, the <strong>Stop</strong> and <strong>To Manual</strong> buttons are
|
|
replaced by one <strong>Resume Auto Running</strong> button, and the computer throttle being
|
|
used by the <em>virtual engineer</em> is released. A human engineer can then plug in a manual
|
|
throttle and acquire the train for manual running. After the human engineer has completed
|
|
his/her work, the human engineer releases the manual throttle, and informs the dispatcher
|
|
that automatic operation may be resumed. The dispatcher resumes automatic operation by
|
|
clicking the <strong>Resume Auto Running</strong> button. Prior to releasing the manual
|
|
throttle, the human engineer should run the train to the same position it was in when manual
|
|
mode operation was initiated. This ensures smooth resumption of automatic operation.</p>
