Another quintessential DG post.
Much use of a different font - that’s unusual dg. The bus stop quirks - that’s classic dg
🙂
I think that I must be mistaken, or have misunderstood the inclusion criteria, but doesn't PLUMSTEAD COMMON THE SHIP (291, 51, 658) also add up to 1,000?

Excellent stuff, I was never going to get that connection!
How do all those routes share bus stop QQ?
Nerdiest. Post. Ever.
Is there a stop adding up to 666?

In the unlikely event of becoming Mayor of London, I will start erecting 'DG Fact Plaques', the only downside being the space required for the small print (excludes non-TfL routes, temporary routes, buses on diversion, school buses, the last remaining Mobility Bus, letter prefix routes and night buses - 24 hour routes are only counted once) as well as 'correct at time of installation'.
I would never have guessed that in a million years ;)
I guessed they added up the same but didn’t bother to check so didn’t realise it was 1000.
My mind has been truly boggled.!
1. That you even thought of the question in the first place
2. That you had the information to hand
3. The sheer scale of the task not knowing that it would even produce anything interesting at the end!

It must have been like reading the mathematical equivalent of the telephone directory!
Makes me wonder how many jaunts into data never get a blog-worthy result now!
How many stops with four numbers or more are all prime?
In my experience a lot of clickbait doesn't even mention the bait it used to draw you in. Twitter is the worst offender.

(and you could add E2 if the numbers were hexadecimal. As bus route numbers aren't quantities you could anyway view them as not usable for arithmetic purposes; in a sense the route "number" is just an easily recognisable symbol. Posibly overthinking this, but with some justification I'd say.)
I did get the answer before it was revealed. Numerology is the main interest at bus stops in places DG has visited so we don't have to.
Alex4D - Even including schoolbuses, I don't reckon that there are any bus stops with 4 or more route numbers all prime.

Excluding schoolbuses, I reckon that there are six bus stops with 3 route numbers all prime: four all have route numbers 191, 313, 491; one has route numbers 353, 359, 433; one has route numbers 107, 263, 307, 606, 634.

Bus stop QQ (Western Road, Romford) is an interesting one. Only six of the buses calling there (165, 193, 294, 365, 370 & 496) are actually listed on the bus stop itself. However, the bus stop does include the notice 'Alighting point for buses terminating at Romford station' - which effectively covers the other seven. As Romford station is the next stop, the clear intention seems to be to discourage passengers from boarding any of the seven unlisted services at stop QQ.
A truly fascinating result.

The cleverness is at the beginning and the end, though. At the beginning, coming up with the idea and getting the database resource, and at the end, presenting the results in an entertaining and intriguing narrative.

The middle bit is a comparatively uninteresting bit of excel bashing, which could have been achieved by any moderately competent spreadsheet wrangler.
