When you spot the Easter Egg ... this is the thread to say you've seen it! ;-)

The lift and escalator going at the same speed is actually brilliant because if you've got a group of people and one of them needs to use the lift, no-one has to wait for each other.

I tricked my wife into a weekend in London solely for the purpose of riding the EL. I was absolutely blown away by it, the design and engineering is star trek like , unreal.

the lizzie line is different level 😍

We all know Geoff's attention to detail is fantastic, but let's not overlook how this filters through to his shooting style and video editing too - you can see how he's thinking ahead to a seamless finished product right from the start. Thanks Geoff! Plus I think some of these new stations look like they could be great locations for street photography. Looking forward to visiting the Elizabeth Line!

The advert surround effect is due to the totems being exactly in the centre of the walkway tunnel. That means that the distance from the viewer to the advertising panels, both directly viewed and as a reflection, is exactly the same and therefore, by default, they have no option but to align. Physics. Great, isn’t it?!

Ever since finding this series I’ve always pointed out the elephant in the room at Waterloo to non-Londoners coming to visit and they find it hilarious. Thanks Geoff!

That secret way in and out on the westbound platform at Barbican is always a favourite of mine

Wooooo!! Welcome back Geoff! Hope you're doing as well as you can be. Thank you so much for being such an inspiration for so many people and we are all immensely proud of you.

The most awaited addition to the series!

I just knew it was coming. But when Geoff tried to keep saying 'If I was doing Secrets of the Elizabeth Line which I'm not' I knew at some point he would but what I didn't expect was for it to be out so soon. Soo happy you made this video Geoff I will sure looks out for all this when I'm next on it, keep it up mate 👍 #purpletrain

Spent 5 years working on the project and was awesome! I noticed something once at Farringdon. The signs for TCR do not show a connection to the central line. They show the northern line black strip but the red strip is omitted. We thought we had found an error but when asking about it, it was said that a computer simulation predicting the flow of people around the tube network had designed it that way. They didn't want to direct people from the EL to the Central Line from Farringdon to TCR. To apparently ease congestion. Sorry if that's a bit confusing but hope it makes sense. Just another little thing we noticed at Farringdon. You'll notice it now lol

Would be fun if the Corporation of London could install a little boundary dragon at Farringdon, at the point the station crosses into the City!

After all these years, the series that made this channel is back!

Literally just finished binge watching all the others yesterday - was in London last week for the first time ever and rode on the tube loads! Impeccable timing!!!

Writing Elizabeth Line instead of Elizabeth line. Absolute madlad. Fight the system.

The posh new front entrance to Ilford is still a building site, so isn't ready yet. When it is (eventually) finished, it will include step free access. The new ticket hall at Romford is very nearly complete.

As we're staying in the vicinity of Barbican Station on our upcoming visit, the Barbican "secret" access is something we're planning on taking advantage of!

If only all trains and stations in the UK were so efficient and modern

I still haven’t been on the Elizabeth line yet, really need to get on that!

The man has gone and done it! Can't wait to see this.

I just had my first ride on the Elizabeth Line today and was very impressed with it. The stations look incredible and it's so quick as well. When it opens all the way through from Reading to Shenfield/Abbey Wood it will be even better! With the numbered stations there is Sevenoaks, Four Oaks, Seven Sisters, Three Bridges, Three Oaks, Five Ways and Nine Elms on the Northern line.

Another secret of Slough is if you look where Geoff was standing, there is some uneven tarmac on the platform. This is where a train pulling into the now dissused platform 6, lost traction and carried on through the buffers.

Geoff, you can always lift up a down day with your ebullience and sheer joy sharing what makes you so happy.

Oh wow! This was certainly unexpected, especially after the Farringdon video!

Geoff needs to do an abandoned video of the old Moorgate branch that ran between Moorgate and Barbican on Thameslink

I love that Hayes and Harlington was so unremarkable there wasn't a 'secret' for it but for Heathrow!

Geoff, your videos are amazing! Your channel is where I go whenever I need some trains in my day. Thank you for creating videos, and sharing them with us. We love you Geoff!

It's absolutely surreal to hear Geoff say "Ilford" and see him standing outside Manor Park. If I'd gotten the right day I'd have simply bumped into him by chance! (Also Wanstead Park is a weird station because it's in Forest Gate rather than Wanstead and is further away from the actual Wanstead Park than Manor Park station is)

That advertising light lines which perfectly match must be a nice coincident.

The ‘Sesame Street’ reference had no business cracking me up so much 😂 (Normalise bike racks that spell out the name of a building)

Hope your well Geoff, keep smiling.

He said he won't make it but it's here, arguably Geoff's greatest series

Tom Scott: "I've made a big mistake. I went to Slough."

I'm still blown away at just how fast this bloody thing was back in May when I travelled to MCM at London Excel. One whole stop to Custom House from Canary Wharf. A lovely journey!

My local station (Harold Wood) finally immortalised on video! A couple of extra Harold Wood 'secrets', though strictly not Lizzie Line related. The original 'Great Eastern Railway' station building still exists, on Platform 1, though the street entrance has been lost behind a housing development. The building now houses a takeaway kitchen. Until fairly recently the old LNER barrier still exited inside, with the gates to close off the station and the benches on the platforms had cast LNER ironwork.

My favourite secret is that if you're transferring from the Elizabeth Line to the southbound overground at Whitechapel it can be much faster to take the lift which goes straight to the platform then to go up the escalator and down the stairs.

Just scrolling through, thought KZfaq had thrown up the old algorithm again for a previous "Secrets of..." Episode... BUT HANG ON, GEOFF'S DONE IT AGAIN!!!

Your enthusiasm, and eye for detail, reflected in your bubbling commentary, intrigues me Geoffrey. I guess that's why, although living on the other side of the planet in Queensland, Australia, I keep tuning in. Thank you for very interesting railway oriented videos. I've been a train buff all the days of my life. (toot toot)

Finally!! Great video Geoff. Just a side note, the series is called secrets of the underground but this not being an tube line is some renaming in order!

Absolute legend. The amount of work, research and scripting that clearly went into this one video is extrordinary! Awesome result!

I used the Elizabeth line to get to Heathrow last week. Saved about 12 pounds vs Heathrow express. Time from Paddington was only about 30 minutes. Plenty of room for luggage. Beautiful and comfy trains !

The totem advertisement reflections was super cool to see!

I was in London (Farringdon area) a few days ago. I was so excited to ride the funicular lift at Liverpool, thanks to your videos! Also, the free transport between Terminals at Heathrow is a blessing.

Geoff’s face in the b-roll as he first mentions Slough is an accurate depiction of how we all feel about Slough! 😂😂

Excellent to see a new "secrets of" video. Brilliantly done (as usual) and so informative. Thank you, Geoff.

Oooh you missed one of my favourite Elizabeth Line secrets - that the lighting in the platform edge doors subtly changes from warm white to cool white when they open for a train

It's nice to see you working with a cameraman, rather than having to hold a selfie 🤳 😄. Great video 📹 👍 👏

Now there's two. Also the captions first letter read out Crossrail

The series is finally back, thank you Geoff!

2 weeks ago I went to the elizabeth line. was a lot of fun! So I think this will be a fun video too! greetings from the Netherlands

I’ve still not had the chance to ride the Elizabeth line but my goodness it is a work of art! Amazing video Geoff!

Awesome video, great to meet you last week. 😀

As always, thank you. What an amazing degree of consideration, thought and creativity has been put into every aspect of the EL. And anyone who saw the series of documentaries on its construction will have an ever deeper appreciation. That said, it is amazing that the wall panels behind the benches on the platforms show the dirt from seated passengers leaning against them. Hopefully a remedy will be found.

He actually made the video I can't believe it! Great job Geoff it's really good

Did you know Freedom passes for disabled passengers (And probably older person freedom passes as well) can go all the way to Reading on the Lizzie line.

6:24 This is for the crowd control when it's extremely busy. Passengers getting out always have the priority to make more space in crowded area.

That's a lovely bit of timing at 1:19 with the LNER on the sign appearing as you say it out loud 🤌🏽

Glad you’re feeling better, Geoff xx

In Singapore, we have platform screen door numbers for all our MRT stations, including the overground/ground ones. Though mostly it's the contracted surveyors and maybe transport enthusiasts who take note of these numbers.

Another interesting thing to note is since Wargrave, Shiplake and Henley-On-Thames have been added to the contactless network, it is way cheaper to reach these stations by tapp your contactless card than to buy a train ticket, even when using a railcard.

Good evening, notification just popped up!

Geoff, I just found a secret way how to go to the Elizabeth Line platforms if you're getting off from the Central Line at Tottenham Court Road. I noticed that if you're following the Elizabeth Line signage when you get off from the Central Line train, it will lead you to the gates where you have to tap out and tap in again but it'll cost your journey cuz you tapped out of the gates. But I found a secret way to the Elizabeth Line without touching out. From Central Line, just simply follow the signage of the Northern Line, go through the platforms to follow the Elizabeth Line platforms where you can see stairs in front of you on the other end of the Northern Line platforms and then just simply follow directions of the Elizabeth Line until you arrived without touching out.

I loved this video, Thank you Geoff. Slough Station was customer friendly with plenty of history on display.

I’ve never clicked on a video so quickly. Always enjoy your videos Geoff as said many times before. Keep up the good work :)

I’m glad the beautiful lizline opened in Her Majesty’s presence and she got to see a train line in her very Own name😭💔 Love you Queen, You are irreplaceable

Great video, I love all the little design touches that have been used throughout Crossrail, Elizabeth Line, Purple Train.

I also appreciate Matt the cameraman's work on this, it's giving you options you didn't have filming yourself.

Might as well call the country Elizabethland

I really enjoy your work Geoff very professional

Great video! And I'm not surprised you spelled "CROSSRAIL" with the first letter in each caption.

That matching elevator-escalator is so fun!

He's only gone and done it! :D

Hey Geoff! Just saw you recently visited the US. Noticed you really didn’t go on any major transit systems while there. So I thought. Next time you come to the US (which hopefully is soon), you can come visit Chicago and ride the L! If to make matters better, I live in Chicago, and I’m not saying you have to, you do whatever since you are the mastermind here anyways, I could maybe show you around! Or at least make a video on the L. Either way, Chicago has a lot to offer, especially transit wise, and it would be cool to have you visit and record about the CTA/Metra!

Another awesome video thanks Geoff. Keep smiling. You are doing what you love and you do it so well!

6:03 - I'm pretty sure that's not "by design" but just "the inevitable result of ads equidistant from the poster, one left, one right".

Of course it’s not a secrets video without spelling out something with the captions 😂

One of the few channels I'd immediately click on the pop-up video.

Got so excited about the Manor Park feature! It’s my Aunt’s local station and in essence my station whenever I visit from Toronto. Your “Secrets” videos are the best (My favourite at least)

Excellent video, Geoff. The secrets that you feature in these videos seem usually to be associated with stations of slightly older vintage, so to see that some of the most modern stations on the network still have their secrets and quirks was definitely very enlightening. I note the caption towards the end that states that Twyford is the least-used station on the Elizabeth Line system. Assuming that I am using the correct statistics (which isn't a very reasonable assumption by any means, as I'm not very observant), I believe that Iver is the least used station, recording around 91,000 passengers last year, with Taplow a close second on 94,000, and Twyford welcoming roughly 200,000. Speaking of Taplow, an interesting historical fact: it was the first terminus of the GWR line from Paddington, from opening in 1838 to the extension to Twyford in 1839 (though the station was re-sited and rebuilt at a later date) and that the new station was built with large and ornate station buildings, certainly for such an inconvenient station (roughly two miles south of the village it purports to serve) - the reason (at least partially) being that it was the local station for several major GWR shareholders!

Another Geoff video done to perfection 💜🚈

Some people have Marvel movies, we have ‘Secrets of the Elizabeth Line’.

0:12 the faint “I’ll probably-“ 😂

I rode the Liz Line last weekend it was glorious! Loving the channel Geoff!

YAY. FINALLY! Well done Geoff

8:27 Southall and Whitechapel have beautiful signage in Punjabi and Bengali respectively.

We Stan the Purple Shirt for this video! You look very cool, Geoff!

Hello Geoff! My son, who has just turned 4, is absolutely fanatical about trains and found your channel after watching your Elizabeth Line videos on repeat. He loves all of them - yesterday before nursery he was calling me: 'Mummy! Come and watch this Geoff Marshall video with me!'. He has also asked when we're going to meet you. So I wanted to say thank you for providing engaging content for train fanatics of all ages. I also wanted to ask, if you or other commenters should feel inclined to reply, for suggestions about what to do to nurture his love of trains. He loves to visit train stations and level crossings and travel by train, of course. We go to miniature railways when we get an opportunity, he has a tube map that he likes to study and he spends several hours a day making a Brio train track. So for those of you who have grown up as train lovers - do you have any other suggestions for things we can do?

Really enjoyed the slick production on this one Geoff. A cracking piece of KZfaqry. 👍🏻😀

2:36 7 Sisters is an obvious match for 7 Kings. There's more? Let me see ... 1stead (and 1stead Park); 2ting Bec and 2ting Broadway. 4est Hill? L8ton? Aha -- it's one of them new ones, 9 Elms.

The art is very nice - and the cold/warm lighting in the core stations is v clever.

Train Sim World should add the Elizabeth Line to this game, also Glasgow metro, Tyne and wear metro, London Overground, Victoria Line, Docklands Light Railway and Paris Metro In France. Oh and more......

Finally!

Did Geoff just read my mind? 😳

Thanks Geoff for yet another informative and most-welcome video.

Ah, Matt the 2nd unit cameraman, who Geoff always brings for long shots, cutaways and GV's, finally gets a name check! Remember Geoff always travels with an entire army of support crew including a PA, director, someone to do his make up, a runner and a full catering truck ready for an endless supply of Pret teas- all hidden carefully at all times just out of shot! Also Geoff, you are not SAT on a bench, you are SITTING on it- sat is past tense! And yes I do sit in 'pedantry corner'!

YESSS

Nice touch adding the Elizabeth Line purple RGB code...

been hooked on this series and rode the Elizabeth line last week! and now this video!

And this one isn't a april fools like the other one😂🤣
