I haven’t done a proper drawing of the lay-out, as it stands at the moment. Since all tracks are down there is no real purpose for a drawing, so I’ll give you a photo of the control panel instead.

Wombat Creek Tramways’ control panel

Obviously the black lines are the tracks. The reason for three tracks going right to the left edge is the tramways will eventually be extended depending on time and room. The necessary points and crossing are in storage.
The red push buttons control the points. Three points are still not connected and one points is unfortunately very unsteady.
The black push buttons control the power to the tram-stops. The tracks are under constant power and the trams will come to a stop, unless the black buttons are activated.
The slide switches are normally one, but they make it possible to stop a tram between stops.
