Great post. Always love to find your writeups of bus routes that I myself am riding.
As I recall the 470 was originally due to be the S7 but this wasn't used due to potential confusion with the 57 at Colliers Wood. The 470 number harked back to a previous London Country route along the Sutton to Epsom corridor, so the original link to that numbering is now no more.

I wish that TfL would gradually phase out the prefixed lettered route, as they did with the suffix ones as they can be confusing/clumsy and for a time it seemed this was the agenda.

Maybe if you slow the shutter speed down to, I guess a 25th of a second or less (and hold your camera device steady) you'll get a better photo of the blind.
Do people know how to slow down shutter speeds these days? Is it even possible - especially in the case of taking the picture with a mobile phone?
There were originally three S-prefix routes in the Stratford area, all introduced c 1970. The S3 lasted until 1982, the S1 until 1989 and the S2 until 2008, by which time there were four S-prefix routes in the Sutton area, introduced between 1993 and 1998.
…is the second paragraph I decided not to write.
B2024: The S7 did exist for a short while, but was renumbered to 470 due to the confusion you mention. Proof from 2002 here.
Nice to see the bus well used on a Sunday, I hope this included the Sutton - Cheam - Ewell section,for which this is a brand new service on this day, as it seems is the included S4 section.

The four perfect shops in prime position in Cheam include a shuttered jewellers (retired nearly a year ago) and not an antiques shop (there is, however a charity shop next to the prime position kitchen showroom).

One new challenge facing the residents of the detached half-timbered villas is that last week the Council embarked on a consultation scheme to make this whole area a 20mph zone.

It's stated aim is to improve air quality (false) and reduce the risk and severity of accidents (hardly any historically). Unfortunately, the real aim (as cited by C100 for which our mayor is the Chairman), is to make driving unpleasant to discourage it, and as the consultation goes on to say, to make it easier for people to walk and cycle, if they wish. This will not sit well with the mainly elderly residents.

The average speed in these roads is above the threshold for a 20mph zone to be mandated, they are mostly wide and straight with good visibility - limited parking, and segregated pavements with grass verges. Not only will this slow the S2 it will make the residents feel they are going nowhere.

In reality most drivers will go at the natural speed and will all have been given free tickets for a reverse speed gun lottery, with the unwelcome prizes being yet another kind of ticket.

Would one of those phone cameras that take several rapid shots and combine it into one work for these blinds if there's no option to change the shutter speed?
(I've just found that my phone (an Android Nord 100) has a 'pro' setting on the camera that allows me to adjust the shutter speed, that I never previously knew was there.)

S7 - one of the few routes missing from the London Bus Route histories site, introduced 16th November 2002 between Colliers Wood and Cheam, renumbered 470 and extended to Epsom from 19th July 2003 - I think it replaced parts of something else (421?).

What makes this puzzling is that the page for the 470 says it replaced the S7 and part of the 408.

The S7 replaced part of the S4, which had itself been extended to replace the commercial 421 a few years earlier.

The renumbering from S7 to 470 took place when the route was extended to Epsom to replace a withdrawn section of the 408, which had provided the service between Sutton / Cheam and Epsom until then.

AI could be used to amend the bus photos to include a completed digital blind in a "productionised" (easily repeatable) way, rather than manually adding a complete blind to each photo.

It would need some experimentation to get the right set of prompts to update an uploaded photograph and limit other changes to ensure the photo is truthful to the intention, but then the process could be shared to other transport enthusiasts.

Similar problem with digital signage generally, e.g. fronts and sides of trains, trams, etc.

Leo - thanks - 421 (08/94 to 05/98), S4 (05/98 to 11/02), S7, 470.

Having checked LOTS newsletters there was an earlier S7 as well as a S6 which the S4 rerouted between Belmont and Sutton to replace in March 98.

The S6 and S7 were short-lived commercial routes operated by Epsom Buses.

Hong Kong introduced LED route display 12 years before London (mind you not the earliest -- Taipei was even earlier), and therefore I met your problem even before I read your blog. The solution is allegedly adjusting the shutter speed, but with mobile phones by default not having this option I usually don't bother.
At least the lack of an S7 does avoid potential confusion with the SL7 which now also runs through Sutton.
Back in an earlier life as an LT employee, I was asked several times at the old Stratford Bus station where the 51 bus (S1) stopped.

It seems that back then, many residents of east London, especially those with not so good eyesight thought the S routes were actually numbered 51,52 & 53. This only strengthened my long standing dislike of prefixed route numbers.

Apple used to give you the 'luxury' of having to pay for 3rd party apps to adjust your shutter speed on iPhones. Don't know if that's changed by now.

The good old Navaho homepage being displayed on the 'new' iBus is quite common too on the 360 -- where some buses from the initial batch of electrics from the 507 and 521 (from nearly a decade ago already!) have ended up. They sometimes work, but even when they do they don't tend to like the bumps accompanied by the hard suspension which make them flicker.

I do wonder if the new iBus (the driver facing part) replacement that TfL has contracted out will have a GPS interface for drivers. It's a thing in France -- not because drivers don't do route learning the 'old' way by riding along, but because it's always useful just in case.
It may be the case that lowering the shutter speed on your camera will enable you to photograph the sign on the front of the bus – if you find a speed lower than the refresh rate of the sign. Maybe 1/120th of a second, maybe 1/60th of a second; either way it should be possible even in daylight.
The "taking a photo of a flickering display" issue has got me thinking. Our modern phones are able to do a lot of clever stuff, so I'd guess it would be possible for a setting to be invented where it took a brief video and stitched together the appropriate frames to produce a picture where the whole display is showing.

Perhaps I should be posting this on a more techie blog, but I'm not following any of those.

Two things from the comments made above:

1. An iPhone 11 onwards (and maybe some earlier ones with software updates) can be configured to do time lapse and other ways of eliminating the refresh rate problem with the LED destination blinds.

2. The comments about Cheam 20mph are inappropriate.
The speeds through the centre of the village at the traffic lights are often less than 20mph anyway and the 20mph limit IS beneficial to cyclists and pedestrians crossing Ewell Road and to slow speeding cars. Many live within walking distance of the centre and there are numerous retired people also cycling in Cheam that benefits them for health reasons too. The lowering of speed limits throughout the capital is certainly beneficial.
