3.3 The Main Screen

When running the simulator the main CTC screen will look like this:


  1. Title Bar – shows the file name of the territory currently loaded
  2. Weekday and Time (in 24-hour military time format) of the simulation clock
  3. Start/Stop button (asynchronous mode only)
  4. Simulation Clock Status (Time factor, “sync”, “dead”, etc)
  5. Change of Time Factor button (“FF”, “Slow” – asynchronous mode only)
  6. Telephone button (black if on-hook, red if off-hook, flashes if ringing)
  7. Alarm button to view outstanding alarms (red if new alarms not yet acknowledged)
  8. Special Commands button (e.g. to cancel route etc)
  9. Lock Symbol (if present stops accidental dragging with the mouse. Press <Ctrl>+L to toggle)
  10. Info/Error Line (example shown below)
  11. Route Info (example shown below)


When the mouse hovers over a particular object, the info line (10) displays some information about this object or objects, and a small popup label shows up displaying some short info. If the right button is clicked a popup menu will appear to allow you to get some more information, or to perform some action on this object. Also, this picture shows some route information (11)
