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.
Not entirely decorative, I think, although each railway had its own
distinctive design. Barge boards serve a practical purpose wherever
they are found, perhaps on your house. On my house, they are of
plastic and very plain. I suggest a practical reason for the pointed
design and vertical alignment of the grain of the wood was to guide
rain to many points to drip on to platforms and passengers rather than
having a mini-torrent at some unpredictable spot.
Thank you. That I had not understood.
A new canopy has been constructed in recent years at my local station
which is equipped with traditional barge board.
Did the new barge board fit with traditional existing GW GC station
features? I have found some of the platform rebuilds on your route
disappointing.
Yes, a good match.
