Horsham station, what's the wire for?

[Robsignals]

Horsham, West Sussex, 2 Island 4 Platform junction station on the Mid Sussex/Arun Valley Line. Built in 1930's Southern style and recently refurbished to a high standard, from the footbridge can see on top of the ridged platform roofs a single steel wire held by insulator like fixings (nothing visible below) along both sides and looping round by the bridge. It's not electrical, think I know what it is but does anyone know for sure or want to guess?

An interesting feature is it's one end of the High Weald Landscape Trail with signs on the bridge but not clearly marked, other end seems to be at Rye station which is also Southern. Any other stations have footpath signs on them?

Is it just on the roof? If so, then it might be a wire to attach a harness to for workers on the roof.

Also short lengths on the outside of the lift shaft with what may be a tensioning unit. Yes, that's what I thought especially for cleaning top of the glass(?) platform Awnings. Not seen anything like it before and it's not clear how to get on the roof, possibly a ladder at the far ends - will look next time.

There was a thread about this last year but I can't find it and I can't remember what the answer was exactly, but I think it is indeed for maintenance staff working on the roof to clip themselves on to.

It sounds like a safety line for working at height harness to clip to
