As you are probably aware this has been discussed on Tony Wright's thread too.
My feeling is that telegraph poles are an important feature but few people look closely at them. For example, a housing estate from the mid 20th century would have telephone poles dotted about because they were added after the state was built, but a 21st century estate wouldn't because they tend to be laid underground these days. However, does anyone really notice how many insulators there are on each pole?
A model of a steam age railway needs telegraph poles. A model of a modern railway needs lots of grey lineside boxes, steps handrails etc.
I think Tony calculated around £600 for his poles and concluded he could live with simplified versions. I agree with the reasoning behind this compromise. It seems the same logic we apply to, say, track where we accept generic flat bottom Peco on larger layouts simply to be able to complete a layout before we die, whereas the builder of a compact P4 layout might be able to justify a couple of perfectly detailed telegraph poles and perhaps even include the wires. Similarly, some people (not everyone) may be happy with a 50 wagon coal train of RTR wagons (with or without minor modifications) whereas a P4 BLT might only have a dozen perfectly modelled wagons built from brass kits.
If you are modelling the station in the photograph then it needs at least a couple whopping great telegraph poles with lots of insulators because I'd have thought they would have stuck in someone's mind if they visited the station. These could be cobbled together from Ratio kits or similar I'd have thought.
There we are. No doubt lots of people will disagree but you asked for opinions GN.
