What's the best way between King's Cross and Waterloo?
Переглядів 2,6 тис.2 місяці тому
Suppose you were on your way into Waterloo from the South West, and you need to get to King's Cross and/or St Pancras. You look at a tube map, but realise there is no one direct route. In fact a TfL WiFi pilot from 2018 discovered 18 unique routes passengers used to get between the two stations. And that got me thinking: which is best? So, I decided to find out!

Riding The Metropolitan Line North Curve
Переглядів 1054 місяці тому
On 13th and 14th of July 2024 TfL were carrying out engineering work on the Metropolitan line between Harrow-on-the-Hill and Aldgate; as such services from Watford were being diverted towards Chesham and Amersham via the North Curve - a rarely used piece of track. So, I decided to ride it!

Very interesting
Great video
Used to Work at Olymipa.wjen the shuttle was 7 days all week using train numbers 151 andb152. They would often be poached at Earl's Court to go down to Wimbledon or sometimes Ealing or Richmond is there werenproblems on the main service.
Every time I see you, I want to give you a hug - cool video again :)
The sightline all the way through the train is really useful when standing up and not holding the bars, you can see which way the train is turning so you can lean the right way just before your bit of the carriage turns! Also recently found out hat the Piccadilly line will be the first Deep Tube to have walk-through trains which is pretty cool!
*Roundel & Earls Court ; Acheived
But! How long if I'm riding a horse 🐎?
do you have snapchat/instagram?
I think you're very cute and adorable :)
North Cuuuuuurrve!!! aaahh, fabulous. hey, Goran!
one route missed walk to blackfriars or 1 stop to southwark stn on the jubliee then bus 63 up to kings cross
Nice video- but please next time test Waterloo - Green Park (Jubilee), then Green Park - King's Cross St. Pancras (Victoria). Tried this route recently and if you're a fast walker at Green Park I'm convinced it can be faster than the Bakerloo cross-platform method.
I love that you think there's going to be a next time! 😅
@@GoranNewsum considering it’s a very popular video of yours I don’t see why it would be a bad idea for a part 2!
Quite a fun idea! You say "okay" and "ya know" a lot :)
😅 That can be put down to nerves!
@@GoranNewsum that's normal, you have a lot of potential
Waterloo to Waterloo East. South Eastern to London Bridge. London Bridge to St Pancras by Thameslink
@@terrymoore9388 considering the proximity of Waterloo and Waterloo East that might actually be a viable route.
good route if you don't want to use the tube (also if you have an interrail pass) but takes easily 2x as long as most quick tube methods
The one thing I kept wondering was: "What about luggage?" If I were travelling into Waterloo from the West Country and then transferring to St Pancras for Eurostar, I would almost certainly have at least one suitcase...
@@andrewbutler7681 I think I do make this point in the conclusion.
8th option: uber Then you can compare time and cost and sensory stimulation across all 8. For time, your bars should probably be presented as a range (min time -> max time, depending on the limits for how long you might have to wait).
@@MostlyLoveOfMusic I had considered the taxi option, but I think that's too rich for my blood!
@@GoranNewsum what about helicopter ;)
or more realistically, one of those bicycles for hire?

The Oxford Circus cross platform change as being a blessing for many trips up from Waterloo to the Emirates
Victoria Line Kings Cross to Oxford Circus the Bakerloo line to Waterloo..... Can do it in 15 minutes
Excellent video! Many people will find this useful if they're not familiar with central London public transport. I am never sure which route to get - for speed and ease-of-connection I'd usually go Victorloo, but last time just for interest I went Waterloo - Tottenham Court Road - Farringdon - Kings Cross St Pancras, so I got to ride on a Northern Line Tube, Elizabeth Line and Thameslink train! I was pulling a wheely suitcase so appreciated the Elizabeth Line's step-free access. Maybe you could suggest a step-free option for those people who can't use stairs/escalators?
@@simon11235 I think Waterloo and King's Cross are both step free, with lifts to platform level, so should be fine for those with heavy luggage and/or people who can't walk far. I would recommend the Victor-loo route because it involves the least amount of walking.
@@GoranNewsum I looked it up on the step free tube guide and for those in wheelchairs the best route is jubilee line Waterloo to Green Park then Victoria line Green Park to Kings Cross St Pancras.
Walk to Blackfriars, maybe stop for a coffee and then Thameslink was my usual route. Waterloo East -> London Bridge (south Eastern) -> St Pancras (Thameslink) also a good route when it’s too wet for a long walk.
This is exactly why I included Thameslink. Like you say, if you want to grab a coffee and have a nice walk along the Thames it's perfect. I'm just glad I did it on a day it wasn't raining!
Northern Line to Euston, then walk down the Euston Road.
I considered that, but thought the extra walk was a bit too much. And if you're already at deep level, it'll take longer to go up to street level and walk, than it does to just change to the other Northern line platform.
But then you don't have the walk up to street level at KX, so that cancels out. The walk from Euston to KX is FAR less than the other walk you did. I think this would be quickest for me (a fast walker with no luggage). There's no right answer really - I would just do a different one each time. Another I've done is to walk from Waterloo across the river to Embankment and take the circle line. Not the quickest, I'm sure, but it avoids changing at least and you get a bit of a view of the Thames.
Really good thumbnail congrats on a new most viewed video
As some who regularly travels on south railway trains to Waterloo and need to get to kings Cross. I get of one stop early at Vauxhalll and get the the jubilee line to kings Cross
@@chhitijpahari1011 I realised this too, and absolutely should have said it in the video. But I think there are some services that don't stop at Vauxhall.
Think you mea the Victoria line? - although unfortunately a lot of mainline services don't stop at Vauxhall. 😢
ah yes, the jubilee line between vauxhall and kings cross, 100% not a case of 'the jubilee line doesnt serve either'
The walk to Blackfriars is usually quicker via the cut (I often did this to get the thameslink train home after work) Great video though!
@@okaykatieokay yeah, I had a look at the map again afterwards and saw I could have cut through the "city" (round the back of Waterloo East) but the walk along the Thames was worth it.
Sorry, this is rubbish. See what Samuelles20115 says ( below)
@@danielmoloney1158 see reply to Samuelles20115
different branches tsk tsk
thar comment said to get the northern lone between those two stations, which this guy did in the video by changing at euston
the journey from waterloo to st pancras cannot be completed by using one continuous northern line train
Northern Line from Kings Cross St. Pancras to Waterloo. Nice and easy, job done👍🏻
Kings Cross is on the Bank Branch. Waterloo is on the Charing Cross Branch.
@@katrinabryce exactly, which means there isn't a direct route between the two stations. Hence the video.
yeah he did that by changing at euston
wait sam is that u? if so its tom the guard lol fancy seeing u here
also hate to say it but thats not possible
I would do the Victorloo route, because of the easy cross-platform transfer. It is also worth mentioning that if you are arriving or departing on a train, then it might be cheaper to add tube onto your train ticket than to pay for a separate bus fare, or it might be included in your ticket anyway. If you are going for a Eurostar, then you can buy a ticket to "London International CIV" which can actually work out cheaper than a regular train ticket to London, includes tube travel to St Pancras, and guarantees your connection onto the next available Eurostar in the event that your journey to London is delayed.
@@katrinabryce this is precisely why I included the bus, I don't know how much adding the tube to a ticket is, but if you're not using the tube loads, the bus has got to work out cheaper.
@@GoranNewsum The cost depends on where you are coming from. From Feltham for example, a single would cost an extra £1.70 off peak or £1.80 peak. For a return, you are going to hit the daily cap whatever you do. For Feltham to Crews Hill, it is cheaper to do a single journey entirely by rail than to break it in the middle with a bus journey. From Basingstoke, it costs an extra £10.30 to add tube to your train ticket. Probably best not to do that, and pay for them separately.

Nice to see a recent tube challenge video. Ive attempt a few minor ones myself but never recorded anything. I did the all the DLR stops and all the Croydon tram stops ones... though technically not tube lines I also attempted the A to Z one where you visit tube stations in alphabetical order excluding a few letters as simply there are no stations begininng with j x y or z....i made good progress but the day i attempted it i was unaware that Icklenham the only station starting with I was out of action 😢 I may attempt it again one day...im also interested in doing The Snake
@@skyblazeeterno I'd love to do the Overground challenge one day too, and the big tube challenge. But they take the whole day and at the moment I don't have the time (or energy) to do that!
@@GoranNewsum yes the A to Z one takes around 5 hours. As I do these things on a more casual basis that would be about 7 hours for me. The Snake takes around 6 hours when done quick so probably 8 hours for me.
Maybe because "Gladiators" TV show had "Travelators...
It's good exercise!
*Mousedrawing 👍
Very interesting video! Just a quick question, what is $\mathscr{H}$ representing in Theorem 1.1? Is it just an arbitrary hyper plane (line of reflection) or am I missing something? (edit : Nevermind I rewatched the section! set of all hyperplanes!)
Good attempt I tried this challenge last year but starting at North Greenwich and finishing Kew Gardens can’t remember what time I did it in as I emailed my time to the explorer ticket email address with all the times of changes I did and never got back and never got updated on to the leaderboard which was a shame . This is the first south London challenge I’ve seen on UA-cam so it was very enjoyable hope to see more of the unofficial tube challenges 👍
@@philipdemicoli7409 I've got some more ideas in the pipeline (or should that be tube line!)
@@GoranNewsum look forward to seeing them I might try the South London challenge again but doing the way you did
wooowww !!!! Amazing
appreciate the zero indexing!! 😄
Under an hour, nice 👍
funnily enough when I attempted it i did a very similar route save for taking northern at waterloo, district at embankment then jubilee to green park and picc to picc circ and bakerloo to oxford circus instead to use the cross platform to victoria. absolutely belted through Liverpool street and just caught the train you missed. got a 41:06
Nice video - thoroughly enjoyed, and nice to see the all lines challenge is gaining popularity again! Not a bad time at all considering how unlucky you were with your connections. To cut out the long walk at Waterloo, I often find it's quicker to tick off Bakerloo and Northern lines to Embankment first, then the District line and Jubilee line before continuing with the rest of the lines.
But doesn't that mean you have to repeat track?
@@GoranNewsum My mistake, meant to say just Northern to Embankment. The Bakerloo line can be ticked off later on (the connection between the Northern and Bakerloo lines at Charing Cross is really quite nasty!) by doing District to Westminster, Jubilee to Green Park, Victoria to Oxford Circus, Bakerloo to Piccadilly Circus then Piccadilly line to finish. Westminster is a little bit annoying to change at but it's nowhere near as long as the W&C to Jubilee connection at Waterloo, which has taken me more than 3 minutes to run before.
@@ItsAllAboutTheJourney aha! I get it now. And yes, I think the connection at Waterloo took me almost five minutes, so that would have been a much better route!
Escalators aren't working? Can they not be used as stairs?
I expect it was a health and safety thing.
There's a chance they runaway afaik
thats really cool thanks for showing the nitty gritty math! Edit: I can't believe Euler shows up here too... he literally did everything
Hey Goran, are you by any chance interested in machine learning algorithms? There might be a new approach to it involving abstract mathematics in order to get out of the alegorical playground of mimicking and just being based off of data for models.
you mean category theory?
@@youtubepooppismo5284 yes i was referring to that paper!
Sounds fun and funny. 😂
