Okay, in theory, but I don’t think that we have that culture of diverting one bus a day via a hospital and one via a school etc in the UK. There are some examples, of course, but often where it does happen you’ll see the “and then at these minutes past each hour” column have a letter at the top of the “47” departure (e.g. “C”) with an explanation at the bottom of the leaflet explaining something like “C - please note that the 14:47 additionally serves King Charles I Academy at 15:35” and runs five minutes later between Midpoint Avenue and Terminus Grove” - it doesn’t get a whole other number, and we don’t tend to do it on a huge number of services, certainly in urban areas
I think that a separate suffix was used when Mainline/ First diverted a couple of journeys a day via Lindholme Prison (a long diversion from the main road in quite a remote place, let’s face it you probably don’t want to build new prisons particularly close to main roads/people!) but when I checked if this was still standard practice I found that it’s now a bi-hourly terminus with a suffix (
https://bustimes.org/services/84a-doncaster-lindholme?date=2022-11-04&service=45328&service=44967 ) - but these are rare examples, we tend to keep service patterns as simple as possible, certainly in anywhere large, often at school journeys are while other rites with whole other operators
Mind you, if I was a regular passenger and knew that the “14:47” would be flooded with school kids I’d quickly learn to avoid that particular journey where at all possible, it wouldn’t need a separate suffix to make me wait for the next departure and have a less stressful journey!
Maybe there’s some research that shows that an occasional school diversion of up to five minutes it’s okay for regular passengers but if the bus is going to be delayed any more than that then they’d want a separate number to be used, i don’t know?
As I said about Lothian, where there are Multiple ways of getting to the sage ultimate terminus, they would use something to identify them, like the 5/51 example that I quoted (not “5a” though) - there was 17 used for journeys on the 16 corridor that ran through central Leith rather than down to Bernard Street (again, not “16a”), same with the 9/10 in Leith, just like loops and circles where there are multiple ways of getting to the same terminus have separate numbers
Edinburgh had a few “true” circulars like the 1/6 and 19/39 (generally withdrawn over twenty years ago) but doesn’t have the tradition that other cities have of corridors with suburban circles/ loops and yet the same final terminus - the 28/29 is the only one that jumps to mind right now
However, services where the destination was enough to convey which way they went didn’t necessarily get a separate number (11s that served Fairmilehead rather than Gracemount were just 11s, I think that 8s which extended beyond the traditional Gilmerton terminus into Midlothian were just 8s, certainly the 50% off 26s terminating at Eastfield were just 26s and the many journeys on many routes that have terminated at Elm Row or diverted slightly/terminated at Kings Road or for Longstone used the regular service number - people look at the destination screen, they with these things out
Doesn’t sound ambitious enough, I think we need to include both versions of Gaelic and probably Ulster Scots too, plus maybe a few alternative languages that are actually widely spoken in the UK like Polish/ Urdu/ Mandarin?
Admittedly the destination screen would now take up 95% of the front of the vehicle, with the driver only afforded a little port hole to peek out of, but if we’re going to start being as inclusive add you want then we might as well keep going
In all seriousness, you do sound a bit too keen to rip up simple routes and complicated them for ordinary passengers so much that they need to carry round a notebook to remind them which services to Terminus Grove they can or can’t use (because, let’s face it, if you’re going to have the two routes mentioned above, there’ll be times in the day/week when you’ll want to run ACEFH and times when you want to run ADEGH because of the lower frequencies at certain hours or whatever, or because we need to balance other times because one route takes slightly longer, so we’ll need four suffixes now even if a couple of them are only used on Sunday evenings or whatever)
Thirty five years ago we had more of the kind of routes that you seem to adore, I remember two Wybourn journeys each evening in Sheffield were diverted via Gala Bingo, minibuses allowed diversions into housing estates that “big” buses couldn’t serve, but the culture post 1998 (the year of the Glasgow Overground) has been to focus on full sized vehicles providing simple frequent routes along main roads, and if the council want to pay for school services then they often use a specialist operator (often a coach tour company) who have a fleet of double deckers
Similarly, train serves in the UK have been settling down as clockface hourly (or better) paterns rather than the culture of “one a day” trains from “Yarmouth to Barmouth”. We seem to understand public transport better when you don’t need to pass a maths test or carry a notebook to work out which particular journey is most appropriate
Having so many variations just makes things off putting, and there’s the question of whether a “one a day” journey is good enough for passengers to rely upon it, it’s fine for school pupils who board the waiting bus when the bell goes at the end of the day but would you hang about outside the hospital for long at the end of Visiting hours for a specific bus when you could board one of the regular buses from the hospital to the city centre and change there

Sorry I messed up the quoting on my phone but
@DunsBus said:
I remember the LRT 81, the predecessor of today's service 37, having five variants of which three used suffixes.
I think that these would probably all have suffixes if they still ran today (since it’s important to know which of the multiple routes a vehicle with Deanburn on the front has taken), although the relative simplification after the millennium removed a lot of occasional diversions across the network
However I was thinking of the 81 when I made my earlier post (but didn’t mention it in the end) because the service pattern off peak was generally every ten minutes from Muirhouse AFAICR but only half hourly south of the city, yet the frequent “shorts” were just 81s as far as I remember, rather than needing a whole other service number to explain that they terminated in the city centre, same with the competing CitySprinter C1 where the five minute frequency became five from Muirhouse into the city centre but every ten to Oxgangs, with the new C11 beefing up the combined City - Oxgangs frequency to every five - yet Eastern/SMT just used C1 for the short journeys. Maybe the difference is that Edinburgh people learn to read the destination screen and have more intelligence than those of other cities, who knows!
