Defining more panels
Because your railroads model can be large and contains a lot of separated stations there is possible to create more than one panel. To do this select from menu: 'Design' => 'Panels list'.
You can add new panels by clicking 'Add' button.
For each panel you can set:
Name: any panel name
Size of cells: size of cells on this panel (in pixels)
Draw H/V llines: switch off lines on panel
Additionally you can:
change then order of panels by pressing buttons 'Up' and 'Down'
delete panel (if is empty!) by pressing button 'Delete'
