Union Pacific Greeley Subdivision - A Real-Time Dispatcher Type Display

Legend

• A white control point name indicates no data has been received going to or from the control point. A white line is a track that has not been cleared by the disptcher, or a section of track where a train has knocked down the green clear signal, but is not occupying that block as of yet.
• A green line is a track that has been cleared green by the dispatcher.

Note:This dispatcher display shows only "controls" sent from the dispatcher to the control points. Thus occupied blocks (red lines) indicating a train's location cannont be seen. But you can monitor the display and watch for green signals to get knocked down to red. This indicates a train has just passed that control point.
