I should love some proof. I'll bet you can't find any.
Bonding and beyond

I looked at the time and believe a phrase with a similar meaning was there.
However the simple crux of the matter is : no bonding - no power! so regardles of the precise wording, the work had to be done to get connected and a house without a box of magic volts had no retail value.
So - no one was willing to stand up and get the situation corrected.
Wood Lane tube station- the SS hand rail running up the centre of the stairs is earth bonded. Other than the light fittings, which are not less than 3m above, there is no obvious power source near the hand rail. That said, I am not being critical of them.

I suspect you are totally wrong.
I imagine there were complaints of electric shocks so the earth bond was added to ensure the static discharges really hurt

The steps are stone, no static electricity would result in a discharge. And from what I can see, the earth bonding has been there since they reopened the previously redundant station.
I see similar things over on railforums with regards to rail ticketing. You can complain all you like that rules are being misinterpreted, but either the company refuses to accept that they are misinterpreting the rules. Or they "accept" it in a reply but fail to actually effect any change to the behaviour of their frontline staff.
I'd understand a paranoid approach to bonding if there was 25kV OHLE around. It seems strange for a DC station though. Maybe someone grabbed the wrong standard.
All metal "hand rails" at Tram Stops in Melbourne, Australia are quite solidly (and obviously) "bonded" to the (Earthed) Tram Rail.
(I will try to remember to take a photo to post on this sight - next time that I am at one!)

The tape wrapped onto hand rails on buses was there to prevent ( reduce ) static electric shocks to passengers as they boarded the bus, Before tyres were made using conductive rubber a high level of static electricity could be built up as the bus moved through the air.
I am not sure but I think the tape may have been designed to create a high resistance path from passenger's hand to the metal rail.
Is it possible to generate static electricity when walking up stone/tile/concrete steps?
The handrail is 6 to 8m from the track, and set back from the platform by glass and steel.
Will take a photo when there next.
To expand on my earlier comment, my understanding is that the high voltage and large loop area of 25KV OHLE means that induced voltages in fences and similar are a real concern.
But I'm not aware of similar concerns for trains supplied with "low voltage" DC.
