- At 18:32 I dip the non-crust end of my pizza in the garlic dipping sauce. I wanted to confess that before anyone complains. It was a long day.
- I said that Cardiff has platforms 1 through 8 and actually there is no 5. I had no idea! I only realised watching Geoff’s video.
- Let me know if you spot anything else!

It really was x-ellent

Aaaaah.
was it accidental? Matt may have meant the pun :)
*Z* puns! They're kill me!
If they add new platform before zero, it is obviously going to be platform 255.
@Rich H (being even makes that obviously wrong) You mean 18446744073709551615
Anyway, in a few more years it will be platform 340282366920938463463374607431768211455
@Rich H a byte (char) will always be 1 byte long, so no, it's still 255

I love the irony of posing for a picture at platform 0 at Kings Cross, when everyone else turns up to pose at the equally odd 9 and 3/4 at the same station!
Neither are odd
@@Tom-u8q Underrated joke
Hence they're equally odd.
They were obviously too embarrassed to pose at the innumerate platform 9¾, in its location between 8 and 9. 😀
0 is even
They can't use 0 in oyster. It's reserved for 'unzoned' transport like the cable car, SE high speed and possibly the trams too. Stuff that doesn't get capped on Oyster.
Ohhh, neat.
trams use the same classification as the bus doesn't it?
You don't often see the cable car and transport in the same sentence...
The schematic diagram you saw with the coloured rectangles is called “CCF”. It is used nationally by railway controllers to see where each train is and its punctuality. I had the pleasure of designing and coding the much of the software for it!
David - proud of you! And mildly surprised it's visible to the public on so many stations.
I was so excited to see that Doncaster has a platform 0, since Doncaster in Australia is imfamous for having 0 railway stations.
I should probably be annoyed that this whole adventure adds up to nothing, but it's hard to be either positive or negative about it...
Glad to see two of my favourite hobbies (and channels) collaborating!!
“I watched one of your videos recently”
“Sorry about that”
Hilarious!
I love how instantaneous that was! Geoff was ready
Is it my imagination or did i just see an almost identical post on Geoff's channel
Interstellar💥 you would be correct! Well observed
I read this comment literally exactly as those words were spoken in the video!
"We will stop at nothing"
I see what you did there.
Bec: I've brought you onion rings, doughnuts and bagels
Matt: thanks for nothing
Matt getting up at five in the morning.
Matt's wife: Where are you going?
Matt: To visit all the 'platform zeroes' in twenty-four hours.
Matt's wife: Okay, have fun.
Relationship goals.
Strangely enough, the time I travelled all of Melbourne's railway lines in one day from 0450 to 0005, it was before I had a wife or even a girlfriend.
Parker trip. Going from point A to A in 18 hours, going literally nowhere achieving nothing.
Waiting for Parker
Parker displacement but certainly a noble journey!
"My train is 45 minutes late".
Meanwhile in Japan: "We're so sorry our train left 3 seconds early! We'd like to formally apologize to anyone who was inconvenienced by this, we've commenced an investigation to find the cause of the error and we are determined to prevent this from ever happening again."
(Train driver commits seppuku)
In 90's I travelled lots in Switserland and in Bern one usually checked ones clock by the train leaving not by the station clock. Swiss train paid your ticket money back if the train was late. So they were always on time even when the station clock did not agree.
“Zero, a great number to start counting from.”
Two minutes later: *starts counting at 1*
Apparently a Parker Array starts at 1.
Many numbers are great to start from
Ends the video by counting UP to zero.
slight indexing PTSD
@@ettpunktnoll I now start array indexes at pi + i. Rational indexes are so 2019. And with two dimensional arrays a complex index is clearly the only real* option.
* pun not intended
Following elevator conventions, the one below the "0" will be "00" if digits are used
I'm sorry for the programmer that will need to handle that
00 house wins... unless you’re using a European roulette wheel which only has 0 and not 00 too.
Man, US casinos cheat!
I’ve never seen that - maybe a US thing? In my experience the floor below 0 is usually labelled...-1! Or else B1.
It's more of a screw face type thing
If you put a platform next to Platform 0, it underflows to Platform 255.
15:55 "We will stop at nothing" underrated joke
What are you talking about? Nothing could be more underrated.
This is wonderful. It was pointless and time-consuming and I think the highlight of my day. I love how genuinely excited Matt is about math, and this channel has renewed my fascination with math.
My real question: how often does Geoff get stopped by random train staff for a chat?
69 likes
In France, negative platforms use letters.
Ah! Hexidecimal.
What a brilliant idea and non-mathematically: I can see where Sydney gets its rail heritage. The stations, architecture and signage, etc. are very much U.K. inspired from the 1850s to now.
"It's platform Zero,
I'm holding out for a zero in the morning light,
They've got to be tough, they gotta be strong,
There has to be a train I can alight.
I need a zero".
After 0 they'll probably go to 00 like in roulette and wire gauges.
0, 00 and 000 are also model railway scales (7mm, 4mm and 2mm respectively).
Just think, this video wouldn’t exist without ones and zero’s, that’s how important zero is!
Good sentiment, bad pluralisation of zero.
("Zeros" and "zeroes" are often both correct, consult your style guide.)
The use of 0 as zone number, may have been 'removed' for programming reasons, like meta-number or such.
I was thinking that too. There may be code embedded in the readers (or the tallying system) that takes zone=0 as a wildcard or a special flag or something, and now it's buried and it would be too hard to dig out (at least for the moment).
4 bits (with a total number space of 0 through 15) for a number that you plan to only have 6 conceivable possible valid combinations isn't actually that bad. When you set a format like that you generally try to at least have a factor of 2 margin, and they achieved that. But then someone got clever about zone codes and thought only in the short term, and then they ran out.
I'd guess it could be a private testing zone for debugging software, or an "uninitialized" value.
It's a Y2K-style problem, all over again.
I was thinking a lot simpler, bad coding resulting in a null error, or a staff/override code
Aye -- sometimes you need a special value for something.
15:23 I'm not sure if it was intentional, but the "Thank you for translating" got me.
"It wasn't on the body, the expensive bit" - *Videographers chuckle*
One of few videos I wouldn't mind the comments being turned off.

45 minutes late in Britain.
Always on time in Japan.
But in the U.S.?
Can't be late if you don't provide service.
amtrak be like "well actually" and proceeds to constantly be late on the like 6 routes it does offer
I took Amtrak from New York to North Carolina and arrived 5 hours late.
They redefined late here in Sydney, and then said 'look! Trains are running closer to the timetable now, yay!''
@@caffeineau I think we can give them a pass for "the track and surrounding area is currently on fire".
Seeing fellow enthusiasts hang out together makes me so damn happy, the joy and energy shared between all of you is electric.
Keep up the amazing work
The train service provided by Northern Rail is purely imaginary. ..
So only GWR is real?
They're kinda irrational.
Northern* They haven't been northern rail since 2016. Wasn't Northern Rail's fault. It was the EU's fault, specifically Spain, which still never delivered the new trains it ordered years ago.
@@carbon1255 Good chip-in. There's the story behind it.
In The Netherlands, the platforms aren't numbered, but rather the tracks they're on. Especially on larger stations, it's not unusual to see some numbers being skipped, since they correspond to platformless tracks. An example is Weesp (www.ns.nl/stationsinformatie/wp/weesp), that has platforms for tracks 1 and 2, and for 5 and 6. Tracks 3 and 4 are used for passing express trains.
I’m sure Gary Brannan would enjoy this video! It’s got trains in it!
Me - a german - sees a "DB" (Deutsche Bundesbahn) train, and Matt immediately points at it: "That's the train that broke down."
Why am i not surprised.
Well actualy it was a DB locomotive pulling a London North Eastern Railway Train, which is owned by the british government.
I think it is only called Deutsche Bahn :)
Bundesbahn gibt's in der Schweiz
@@mandelbrot91 It used to be Bundesbahn until the fusion with the east German Reichsbahn in 94.
@@kedrak90 ahh okay. I was Born in '91 - that will explain
It was a DB Cargo locomotive. And I assume it was used to pull the broken down train.
1:47 Two practical reasons for not renumbering the rest of the platforms:
0: all the station signage needs to be changed
1: the signaling software needs to be re-written to update the platform numbers on the screens in the signal boxes, on the platforms, and the illuminated numbers over some signals
2: the "diagrams" showing what train goes where all need to be changed
Given those reasons, it's more straightforward to slip in a platform zero.
Trains late, trains cancelled, packed trains...
This is what i call a Parker Trip.
"Zero is a perfectly good number and if you ignore that you're peril"
*"The problem is that it's a dangerous number and a lot of things can go horribly wrong with zero"*
Mmmm, classic Numberphile reference
It's all fun and games until someone divides by a black hole.
one day they will need platform -1.
a small town near mine has a small train station that beats it all. when you come in from the east, you're directly on platform 2, which goes north. you can go down a tunnel to platforms 1 and 3, which share an "island" and both go south. and here's the really weird one: there's a branch from the northbound track a bit further south that has the number 6. it gets used maybe once a month for passengers (if an out-of schedule freight train needs to pass). there are also a couple of extra storage tracks, which seem rather unused.
overall, a train enthusiast's dream.
I know I am a late commentator but it has to be said 09:00 when Geoff presents the early Christmas gift shirt, Matts response is everything! The sheer gratitude. Love it!
"I have no idea why anyone would be a train youtuber"
Jay Foreman shade
It wasn't Jay shade but foreshadowing to Geoff.
I love how at the same time, you ended up visiting all three capitals of mainland Britain: Cardiff, London and finally Edinburgh.
Hi Matt yesterday I received humble pi as Christmas gift and Im really enjoying it, it's awesome 💯
I love how you start out at Cardiff and tell me something I never knew about my nearest big station.
want to know a really shocking fact:
in the Netherlands the is a town called Nijmegen the trainstation there counts the rails in a bit of a weird order.
it starts with 35 then 1 3 and then 4
What??? The maniacs! They shouldn't be allowed to get away with that kind of thing.
"Can you have minus numbers in software code?"
"Yeah!"
... Matt confidently says about code that was probably last touched in ca. 1994. 😆
"thanks for nothing" is such a good response lmao
Rotterdam Central Station had a "Platform 0" from the late '80s to the early '90s, but it wasn't an actual platform, rather an area outside the station (next to platform 1) where junkies gathered. Methadone and clean needles were distributed there, but the concentration of customers attracted dealers too, as well as junkies from other cities, even from outside of The Netherlands.
nl.wikipedia.org/wiki/Perron_Nul
'Naughty' of the train companies to possibly delay the venture.
You just know that if they introduce a "Platform -1", some piece of software is going to interpret it as Platform "true" and cause a horrific accident. Someone should write a book about stuff like that.
Dom but platforms 1and up are also « true » in a Boolean test
I think the most likely thing is them using an unsigned int so it will underflow to - 1
That might cause an issue if for some reason the software uses different sized ints in different places. There's basically no chance of anything going wrong unless an underflow happens in that case (no station will have thousands of platforms) so that sort of bug may exist, whereas other bugs would have been caught and fixed long ago.
"Platform -1" sounds like the title of Matt's next book
@Blan Morrison That's a great name. Surprised nobody has thought of that already!
20:04 "We could be zeros just for one day."
Best joke in the video. :D
this has such a wealth of sleep-deprived comedy
17:08
"I watched one of your videos recently"
"sorry about that"
The content I didn't know I needed.
Cannot believe Hooton Station gets mentioned 😂 the only other time I've ever seen my local(ish) Station mentioned is by Bill Bryson when he said "Hooton offered the world not only a mildly ridiculous name, but the dumpiest British Rail station I ever hope to sneeze in."
"We're going to stop at nothing!"
I've dropped the exact same lens, and it wasn't too hard to fix it. Just take out a few screws on the back, pop the innards back into their tracks, put it back together, and it's served me a couple more years with no issues.
I never realised this was weird. I'm from Redhill and just never thought about it.
Leon Freeman - I’m in Reigate and still awaiting the need to use platform 0!
@@MrGreatplumreally I've ended up at platform 0 quite a lot from reigate
Leon Freeman - I think I need to get the train more!
Gravesend Platform zero was previously platform one, and was renumbered after another platform was introduced in the middle and became to new platform one.
"Happy zero day!" Usually a zero day isn't happy. XD
"We will stop at nothing!"

"Available now, via a convoluted RSS feed" 😆
I love me some convoluted RSS feeds!
This is the perfect video. Math UA-cam and train UA-cam combined = greatness.
15:54 "We will stop at _nothing_"
I see what you did there ;)
Damn, beaten to it by the video :( 19:48
Whenever you have a storage location in a computer it always has a value. The problem using zero in an automated system is that when things go wrong, values are not initialized properly, devices fail, storage locations sometimes improperly go to zero. That could be a reason for avoiding zeros as being a valid number to use. Of course with 4 bits 15 is also a potential problem. Great video.
Singing - "Zero my hero, how wonderful you are" Schoolhouse Rock taught me to appreciate zero 30 years ago!
like ten years ago I discovered the magic of math youtubers
and now I'm discovering the magic of train youtubers
"You gotta dump that hero, and get yourself a zero!"
There are indeed many unsung Zeros out there...
if you're going to eat pizza on a voyage to find zero, you should have had a none pizza with left beef
I feel like UK youtubers have been collabing a lot more lately and I feel like we're in the endgame now
It’s good you didn’t choose to visit all platforms with the smallest prime number
Why does this feel like a Geoff Marshall video...
Geoff Marshall shows up
I'd like to ask, was there hamiltonian path between all platform zeros?
Geoff marshall is a legend
One of my uni professors said the first day of class "if you consider zero a natural number please leave"
I would have left very proudly
In Belgium 0 is a natural number. You can count 0.
The train station in Zurich is a bit funny with the platform numbering. The platforms in the main hall go from 3 to 18. There are no platforms 1 or 2. They used to exist, and in a way they still exist, they've just been renamed to 21 and 22, because they're underground. The reason they were named 1 and 2 is that originally all the platforms were named by position south to north, regardless of elevation. But that changed when later they added more platforms.
Also, until recently they had four additional overground platforms next to 3, but they were named 51-54 for some reason.
I need a zero! I'm holding out for a zero until the end of the day.
Just FYI: Hamburg public transport uses a three digit system for its zones, first digit is the "oyster level", so increasing the further you get from the center, the other two digits are the rays. And the central zone, where e. g. the Town Hall or the Alster Lake are situated, is "000".
Leeds actually has an unfinished platform 0.
It would be really satisfying for stations to use complex numbers for platforms on different levels
Amount of Fares given by group of people:
Us - 1%
Math youtuber - 99%
Another interesting fact about Cardiff Central is that, although there is a sign for platform 5, it not longer exists as it was a platform for terminating trains only and sat between platforms 3 and 4 I believe. At some point, they decided they didn't need it anymore and so filled it in but left all the signs for it.
I would assume that zone 0 is considered invalid or unset and that's why it's not used
Absolutely, zero is used as an initialiser and signifies empty or unset. Also known as null, and the binary representation of false, it's a good value to reserve as an obvious error or invalid state. And while I understand the embedded system restrictions of oyster and commend the data saving efforts of TFL with using 4 bits for zones (I've bitpacked many structures in the past and still need to now!), it doesn't seem forward thinking..
At one time, Leeds station had platforms W, X and Y, but they were renumbered 1, 2 and 3 when the station was rebuilt in the late-1990s/early-2000s. Platform W was divided into platform Wa and Wb, but (unfortunately from the comedy point of view), no platform Wc.
Rail traffic at Leeds is still growing, so soon it will have a platform 0.
"We need to build one next to one, but the other way."
"Let's call it 0."
But what if you need to build even further the other way? What'd you call that? Platform -1??
platform 255
I'd like platform 0a, 0b then eventually 0o
Luke Ryan oh, I like your idea, but you could call it 11111111
Platform 65535!

My old Maths teacher always said: "0 is not nothing!"
"Zero, a great number to start counting from"
Me: *laughing in zero-indexed arrays*
and then there's lua arrays
Languages that number arrays from numbers other than 0 have always felt strange to me.
@@nomadMik I constantly have to rethink everything. While programming, I have to remember to zero index. While talking to others, I have to 1-index, else people think i'm crazy. It's so strange to flip-flop between the two in day to day life
@@andreyrumming6842 depending on your memory constraints, you can 1-index your arrays with few issues. Or, if your language allows it, you can overload the [ ] operator so that you can use it in a way that is intuitive to you.
I had a really cute encounter about the number zero with a little boy in the US 3 years ago I just remembered when I saw the end of this video.
I visited Pennsylvania State Railroad Museum & Strasburg Railroad and was sitting in the restaurant, waiting for my food, the boy (11 or 12 probably) with his father also at the next table. I meanwhile checked something on my phone and my lock screen is a digital clock full size. So the boy noticed it and was really puzzled about this:
"Excuse me, Sir. Why does your clock say 13:52?"
"I'm from Europe. That's how we have digital clocks over there. At noon they continue 13, 14 and so on. And at midnight they go from 23:59 to zero."
The boy's eyes grew wide: "You have zero o'clock in Europe? Cool!"

@@standupmaths I was reading your book in class when my teacher came up and asked about what I was reading.

You missed a sponsorship trick by not having a Dire Straits soundtrack; and it would have covered your lunch costs.
Yes, that's right: Money for nothing and your chips for free.
Every array should start at zero, makes sense to extend it to train platforms
I just came here from Geoff's channel after waving at Matt's camera on that video, to wave at Geoff's camera on this video.
A platform 0 is normally built due to congestion!
5:37 says 0 is a perfectly fine counting number yet still start counting from 1 🙄
He said nothing as he counted up :)
He was using the ordinals however platforms clearly use cardinals as evidenced by platform 9 and 3/4.
He also did this when he referred to platform 1 as the second platform.
Forget platform zero. Bec Hill is a platform hero.
