What is the name of the design feature often found on canopy edges,
whereby vertical planks of wood are separated by notches which have a
circular hole at the top of the notch? You can see it in the picture
below, which is of Borough Green & Wrotham station. Does it have a
functional significance, for instance does it reduce the turbulence
caused by 100 mph vehicles going past in some way, or was it just a
fashion which for some reason was copied to an astonishing extent on
railways but nowhere else?
AFIK, purely decorative. There were some beautiful examples on the
Barnet Branch of the TfL Northern Line. It has been thirty years
since I was last there, so they may have gone.
