This shows the angle from level 2 to level 3.

This is a viaduct curving above a river and embankments.  It is on an incline from level 2 to level 3.  The viaduct is handmade, originally cardboard but strengthening it with plastic. Some legs of the viaduct need lengthening to fit the layout.  The board,  top left,  is level 3.

This photo shows you level 3 board on the left and incline bridge going up to level 3 from level 2 on the right.  Next to the bridge will be scenery including a hill.
