These are compact slope piers for Plarail, smaller than the mini bridge piers and sloped curve rails. They are very simple and do not protrude from the rail width. The piers are gray, similar to the real-class or elevated rail colors. They can be used with double-track rails, making it easy to create three-dimensional double-track layouts and figure-eight layouts. Slopes can be created on both curves and straight sections.
