The following definition of point clip is from wikipedia.
"To clip and scotch a set of railway points uses two pieces of equipment to temporarily lock a set of points into a particular position. The point clip clamps the end of a moving rail of a set of points to its associated stock rail, and the scotch is a timber wedge used to ensure that the other moving rail is kept away from its associated stock rail. In this way the points are fixed in either the 'straight through' or 'divert' positions and cannot be moved by the usual setting mechanisms. For infrequently used points, this guards against mechanical failure of the points leaving them in a condition to derail trains. The 'clip and scotch' method can also be used to positively deny access to the turnout or mainline."
Couldn't resist the temptation, so a wet Monday afternoon produced the following.
