+- *Steel Railings, Catwalks, Catwalk-Stairs*: Railings can be placed on every block with
+  a solid side  and easily be removed by clicking again with a Railing in your hand. There
+  are two craftable versions of Catwalks, top-aligned ("raised") and bottom-aligned (it
+  depends on the situation which one is better). Railings can also be placed on bottom-aligned
+  Catwalks. Right-clicking on the top surface of a Catwalk while holding another Catwalk
+  in your hand places that block horizontally in the direction you are looking (not on top;
+  makes it easier to place raised walkways in your factory - without sneaking and trying to
+  click the rather thin side). Catwalk Stairs have the same feature, except that they are
+  placed one block up or down in front of you when clicking on the top surface while holding
+  another stair in your hand.
