Retaining Walls hold back debris along railway rights-of-way. They can be used individually and in groups and can be modified to create stepped wing walls or curved walls.
Retaining Walls can be joined together in groups as pictured or used individually.
By mitering the adjoining corners, walls can be made to fit around a curve.
Trim off varoius lengths from the bottom of the pieces to form stepped wing walls at the sides of tunnel portals.
