First time I've seen this....

Wigan North Western, Platform 4 London End.

There is a banner repeater at the London End of the platform as the next signal is round a right hand bend. However when that signal has a green aspect, the background of the repeater changes to green instead of the usual white.

Are there any other examples appearing on the network?

Yes, I think they are now standard for new banners. The idea is so drivers in particular know they have a green so they don't need to start braking. This is particularly important for freight trains as a brake application can lose quite a bit of time.

Very common now. On the west coast they are at Norton Bridge UF, Wolverton UF, Bletchley DS, Watford UF. They are at many other other locations too.

Also useful for if you get checked right down from a single yellow as if it turns green when you still quite far away you know you can open up as it can be difficult to tell the difference between white and diagonal and white and horizontal untill you are fairly close.

Plenty on the MML for the linespeed improvements, eg DF on approach to St Albans.

That was a host of swift replies - thanks. Been around since 2007, that does surprise me. You can see where the money is spent then, here in East Anglia we have only just stopped using paraffin (haven't we? :) )

Is that a serious question? (It is late!!) if it is, they are also used when the signal can't be seen for X amount of times due to tunnels/bridges etc

Why weren't they called 'bend repeaters' ?

'Banner' simply refers to the original mechanical style of that type of signal; to differentiate it from a more usual semaphore arm. If you follow the link to railsigns a few posts above the text also refers back to 'banner' type running signals (sect. 2.68).

Indeed so. The first banner signals functioned as shunting signals (see 3.31) and some of them were 'three-state' banners (see 6.20). That was in 1898.

I noticed some new ones today on the stretch of the WCML slow lines between Norton Bridge and Crewe, where the line speed has just been raised from 75mph to 100mph.
They seem to be larger displays than usual and are mounted on odd-shaped angled posts which lean in towards the track (on the Down Slow anyway).
