These compact slope piers are more compact than Plarail's mini piers and sloped curved rails. They are very simple and sized to not protrude from the rail width. They are gray piers, similar to the rail color of Real Class and elevated lines. They can also be used with double-track rails, making it easy to create three-dimensional double-track layouts, figure-eight double-track layouts, and more. Slopes can be created on both curves and straight lines.
