As well as not knowing or having ever heard of Campbell Brodie*1, Telegraphpoleologist, Disco Dave (#526) regularly travels the countryside looking at telegraph poles for a living. He told me that as well as “C” & “D” poles there could also be found poles that were marked “H” or “Z”.
Oh, how I scoffed as I quaffed my creme-de-menthe down at the club that evening. Little did I know that I would be the one with advocaat on my face. For here it is, proof positive of the rarely sighted “Z” pole.
He tells me…
…these poles basically mean there is a hazard next to the pole i.e. the spiked fence, but the engineer can position his ladders in such a way as to reduce the hazard rendering it safe to climb.
Well I never.And there we are, the spikes are there too. Thank you for that Disco. But “H” poles, really ?
By the way, an answer soon to come on the long awaited question of “Depthing Tubes”. Also courtesy of Disco Dave.
