- Use the arrow keys to move the camera to the end of the siding. You can pan the camera around by right-clicking and dragging the viewport.

The blue pole marks the "End Node" in the track database for this track.

- Once you've clicked, the signal should appear in outline:

Fig. 6: Newly placed signal, in outline mode because it is selected.
The signal should be facing off the end of the track. The red track marker should be pointing towards the blue pole.
- This signal needs to be here so the route doesn't freeze, but it isn't to be used by any trains, and so it should be buried.
Because it's already selected, it's ready to be manipulated.
You can use the down-arrow key on the number pad to lower it all the way into the ground.
OR
You can open its Properites window by pressing F6. Then enter "-9" for the "Y" coordinate:

and then press OK.
The red track marker will still be on the track but the signal itself should now be under the terrain.
- Now to save the changes you've made. You'll want to find a less-populated area to save in.
