clearance

I'm looking for information about clearance signs.

Sometimes you have special signs at the point where the two tracks come together (at the turnouts), where clearance ends.

How do these signs look at the different railroads? Have they changed over the time?
Any pictures would be helpful.

. it has various railroad traffic signage among others.
