For lovingly-crafted instructions and stickers for the trains in this video, check out: eggybricks.com ➡ (including a much-improved Polar Express!) Btw, we fixed the Polar Express and made a few more GE Evolutions - check them out in our newest video: kzfaq.info/get/bejne/sM6UmMyVxLyde6c.htmlsi=12gkiWcWKlBlu6zm&t=167 🚅 We missed you all, thanks so much for watching!!

love the "brick science city is flooded at the moment" referencing brick science's 30 day building a lego city series, along with the micro scaled daily bugle!

So honored to be featured, and I'm glad all the trains made it here! Your builds are truly beautiful, you all are setting a new standard for Lego KZfaq in both video quality and custom build quality. 5 custom trains in one video is simply ridiculous. Loved the micro build also :)

"We could draw on our years of experience engineering vehicles in real life." Well, that explains a lot.

This is genuinely one of my favorite channels on the platform right now. One of the few creators who really take the LEGO brick to its limits without absolutely ridiculous amounts of studio space, or amounts of brick. Love the idea of every city being connected, too!

Fun fact: The Shinkansen was so fast and loud coming out of tunnels that it was creating sonic booms and was becoming a real problem to people who lived near the tracks. The company who made it wanted to fix this so they put a team together to fix the problem. One of the engineers was a birdwatcher and noticed that the kingfisher bird had a specially shaped beak that allowed it to smoothly cut through water. He showed the rest of the team that and they remodeled the nose of the train, and the problem was gone. There were no more loud sounds whenever the train came out of tunnels.

I’m amazed at how much you two continue evolving your quality despite already setting such a high standard. My mind was blown at the technique used at 6:17. You’re approaching god-tier status at Lego YouTubing.

As a Canadian, I'd say your CN GE ET44AC looks wonderful! Love how you sculpted it with the limited width you had! Keep up the amazing work! :)

I wish there were 100 eggy bricks videos so I could watch forever!!!

I absolutely loved this. A few comments if I may... 1, Lego trains can get very expensive, very quickly, as I am sure you've realised. But they're completely worth it in my experience. 😊 2, Jacob's bogies look great, but for Lego trains with many curved tracks they rarely work well. Due to the tight curves, the rolling resistance of a single bogie with a longer wheelbase, maybe 4 or 5 studs between the axle blocks, will be significantly higher than that of two short wheelbase bogies where the axle blocks are adjacent or only one stud apart. (Try rolling the bogies down a straight slope with a long curve at the bottom.) 3, A secondary problem is that true Jacobs bogies have the pivot points for both carriages located at the centre of the bogie. With Lego implementations that is almost impossible to achieve and the pivot points end up being several studs apart. This is in part due to the tight track radii placing the carriages at significant angles, creating clearance issues on bends. The result is that carriages with Lego Jacobs bogies still tend to move laterally relative to each just as much as with conventional bogies when moving through S shaped bends, such as those created when using the turnouts. 4, For smoother running of bogies with metal axles, a tiny drop of silicone base lubricant on each bearing surface in the axle block can make a big difference. I have used lube sold for Rubiks Cubes (for speed-cubing) with good results. It's designed to be safe with plastics, compared to conventional mineral oils. Please don't take these points as criticism, though. Rather, I just want to share what I have learned, having already gone down this path. I always look forward to your future videos.

Seeing a Canadian National train made me irrationally excited lol. Excellent job as always!

The effort put into these videos is beyond what almost anyone else is doing in the Lego community and it really shows.

This was a cool video. Being Canadian, the CN train is my favorite. Another thing is how that I was surprised that this video is so new! Usually this videos would be 4-8 years old being watched in a school classroom (I predict it will because its so good) Great job! :D

This is crazy. It is such an impressive build. It deserves way more recognition.

The sliding middle axles... so genious.

I can hear grumbling from Electro-Motive Diesel on your choice of building the GE Tier 4.😂

The EMD FT would be a fun challenge with the iconic bulldog nose

literally every train fans dream

As an EMD fan myself I would want you guys to build an SD70ACe.

I really love that Polar Express model

Fantastic video as always, it was well worth the wait! Excited to see what you both come up with next!

That sliding middle axle! 🎉 So cool!

The door mechanism using the droid arms is simple and elegant, big fan of your work!

Awesome video!

What a triumph.

That sliding 3 wheel bogey is pure genius.

A few fun facts in chronological order: Jacobs bogies (named after a German mechanical railway engineer), do reduce rolling resistance, and are also used to put more weight on driving wheels, while also reducing overall train weight. They can perform tighter turns, and have the smooth ride of separate bogies without the additional mass and drag (more mass means higher inertia, which reduces acceleration). Talgo trains used a modified concept of the Jacobs bogie, with the wheels able to spin independently of each other (wheels are normally joined by a fixed axel), which eliminated hunting oscillation. Jacobs bogies are most commonly found in trams and urban trains. Instead of sliding wheel sets, locomotives with a long wheelbase often have what are called 'blind drivers', which are wheels without a flange (this can be seen later in the video). This is much more common with steam locomotives, where all the driving wheels have to be in line, and on narrow gauge lines, which have tighter radius curves (or both). They rely on the wheels either side of them which do have flanges to stay on the track, but have been filmed overhanging the track by a wide margin (which would obviously derail the locomotive if those wheels had flanges). The Shinkansen, or 'Bullet Train' used to have a shorter nose, but residents near tunnel entrances (and exits) found that when a train would enter a tunnel at track speed, it would create a sonic-boom-like effect, which was quite disturbing, so designers came up with the extremely long nose you see in the modern trains (derived from the kingfisher bird) to mitigate this issue. The aerodynamics of both are relatively equal, but the sound when entering a tunnel is greatly reduced with a longer nose. The 2-8-2 configuration refers to the amount of wheels in the leading truck, the amount of driving wheels, and the amount of wheels in the trailing truck respectively. Leading and trailing trucks of steam engines are primarily used to reduce hunting and derailing at higher speeds (leading trucks reduce this for forward movement, and trailing trucks for backward), since with these trucks, the driving wheels are guided down the track. To get the maximum power out of a locomotive, you want only driving wheels, since then all of the weight is on them, and they have the highest traction with the rails that they can get, but this also greatly reduces stability (as Hyce refers to it: the 0-6-0 dance). You will often see faster locomotives with leading and trailing trucks, and slower ones, such as tank engines, without. Tank engines are often used as yard locomotives ('switchers' as referred to in the states, and 'shunters' in the UK, with switching and shunting being the associated terms for moving cars around a yard respectively), since they don't have to move as fast, and benefit from the higher traction, acceleration, and power achieved from having all the weight on the drivers, without the drawback of speed limits and limited fuel capacity. Trailing trucks are less important for most tendered steam locomotives, since shoving through a tender is generally not a good idea at high speeds or high power, so you may also see locomotives with a 2-8-0 configuration, or 4-8-0, or 4-8-2, which puts more emphasis on the leading wheels. Modern DE (diesel-electric), electric, DM (diesel-mechanical), and DH (diesel-hydraulic) locomotives do not have leading or trailing trucks, as each wheel can be independently powered whilst also being on a bogie (except for DM locomotives, but these are often smaller and don't require bogies). This results in all the benefits of a tank engine style construction without the drawbacks in regards to stability. They are also much more mechanically simple, so require little maintenance, and are much more fuel efficient than steam locomotives of comparable tractive effort. I enjoy both trains and lego, and it's great to see creators pairing them together for those such as myself who wouldn't be able to afford it, keep it up!

what i love about this vid is a few references that railfans like me might notice. - Canadian National Decals on the Freight Train. - Polar Express - The JR 700, (the livery on it was possibly inspired by the Rail Star Livery) - San Francisco Tram also there's a slight error at 10:46 the locomotive seen in the sketch is actually an FEF Design by the Union Pacific. Not a Berkshire design. but beside that error the polar express model did come it pretty well, even though with the incorrect sketch.

Nice work!

Incredible stuff from you two-again! You’re like no other LEGO KZfaqrs I know. Terrific material.

Very nice layout. Even without the 3D-printed Trixbrix infrastructure.

I have to say it, probaby someone said before. There is a great formula in this channel for a Lego Masters team. Lego love + Lego technical ability + team work + organisation + storytelling! + willingness to go out of comfort zone. I don't know that kind of exposure is in your alley but it would definitely grow the channel. In that scenario your only weakness might be perfectionism, I dont know. I don't know. This channel became my favorite lego channel.

The two of you keep blowing me away with every video you make. The time and effort put into the builds, the video production, and the overall final product is truly amazing. I've never had the interest to do a Lego train, but I do now (my bank account is furious)! Fantastic stuff!!!!

This is a cool channel :) Love the small animations in between the clips

I'm blown away by how how quality this is. You guys are wonderful!

It's my first time watching this channel and I have to say that this is so high quality!👏 You are both so skilled and creative. My favourite is probably your metro or the polar express.

look forward to all of your videos. amazing as always. love that you two are nerdy and convey your knowledge and interests while also making aesthetically pleasing and funny videos. can always expect that you two will go above and beyond in terms of effort and production value. love the cute stop motion interludes on this video, for example.

Nice you added a Canadian national train

I love the idea of every LEGO city being connected. Reminds me of the imagination I had when I was 8 😂

Built well and informing - a train guy

you rock. this is unlike any other lego youtube on the scene right now. I love this and I cannot wait to see more

This makes me cry tears of joy, but could you raise the roof of the cab of the Polar Express by a bit? and i will definitely be using that 3 axle bogey design

The technic for therailings for the freight train was impressive. Very cool trains

WOW! This video is honestly so high quality. Very, very well done!

Really adore the "engineering science communication" vibes of this one! What a delightful introduction to trains.

10:48 what is this? “Polar Express: West of the Mississippi”

Mad respect for Lego train enjoyers

Just love the design of your trains❤

Very impressive build on the steam train. It's sad that Lego don't take their current Lego trains seriously. Back in the 80's and 90's the Lego Train System was a proper train system with all the correct bells and whistles. Todays Lego trains always feel like they are made to a price and are usually lacking the stuff that makes model trains awesome.

Thank you for making them 6 wide!

You two never disappoint! You have already set the GOLD standard for LEGO KZfaq with your first few videos and you still continue to amaze us every time! 🚀

i love the second train they made. the freight

THANK YOU FOR THE INSTRUCTIONS!

This is incredibly well produced. Can't imagine just the filming and editing time it took alone. Fun watch!

Phenomenal job producing this video in every aspect. I am blown away by your creativity!

I wish I could be as smart as you two. Y’all’s problem solving abilities are so casual which makes it all the more impressive

Incredible work. Not just one, but 5 great trains! Wish we could like this video more than once. Can't wait for your next update!

i think you guys make the best lego content on youtube fr

I love the attention to detail and realism! Great work!

i love how much effort was put into these builds! Keep up the awesome work :)

Waiting for that high speed train from NYC to Eggopolis 🙃

This channel is so good. I ADORE your sentiment that all of our Lego cities are connected via trains!! Reminds me of the time I learned that the stars in D&D are other people’s games 🥲

I eagerly await the Polar Express instructions. It's one of my favorite movies! I love your content by the way! You ladies really set the standard.

The tram and the polar express made impression for me. Would love to see a full train or tram system with that theme.

the way they snatched the first train was personal.

Really like all of those builds, especially the polar express and seeing the engineering you put into making that work. Thanks for sharing.

I like your brick trains. 👍🏻👍🏻👍🏻 plus satisfying.

You outdid yourselves. Spectacular video!

I couldn’t help but leave a comment with the pure dedication you put into your Lego projects

while building the GEVO (GE Envolution seiries) locomotive, you called the rear of the locomotive "the radiator cab". It is actualy called the Long Hood End as the nose is refered to as the Short Hood End.

This is so well made, all of the sets and the video! Love it

The 3 wheel bogey assembly is particularly inspired - I would love to hear about how you came up with the design, and iterated toward that particular solution!

I LOVE TRAINS

Beautiful MOCs! Well done!

I have no idea why trains are so interesting, but something about them makes me intrigued.

The quality of these videos are always incredible. You can tell there's real passion behind it

the fact you bothered to get the driver quartering right on the berkshire earned my subscribe

I think you should've used the steam train as an opportunity to teach about the many volunteer run heritage railways.

As a Canadian, I’m honoured to see you use Canadian National Railways.

I love all of your films :) professionalism at the professor's level but spoken straight from the heart. I'm waiting for the next or maybe some shorts from Eggopolis (a wonderful concept of a city with many levels)

So cool that you guys are in the bay too!

i kinda would want to see eggybricks collab with brick science

Y’all these videos are so impressive!!! I love you guys and am so excited to see this channel grow

All these videos are a great inspiration for others to tell them to make what ever they want with Lego and your imagination is the only limit and I have only watched 3 videos and I love all of them

I dunno of you’d see this but, it would be cool to see you guys try to power a lego boat. Like a speedboat.

6:36 you can also use a normal technic motor and some gears to have 3 axles but powered. middle wheel needs to be without flanges, using plate round 2x2 and the fitting tile round 2x2 with a hole in the center.

I'm so excited every time you release a new video. This one again was entertaining and gave unique insights and tips. Keep up the great work.

This channel is a breath of fresh air in a sea of dime a dozen "content creators". The production quality is great, the content is interesting, and you guys dont put on some over the top silly persona just for clicks. Artistic integrity does still exist! Good job

They're all incredibly cute and creative, especially since you've done them all freehand. And big props to the gearbox of the polar express, it's always a struggle to make something small look good while also being functional. A criminally underrated channel with two awesome people, I can't wait to see what's next!

Amazing! The techniques for building the wheels in each use case was particularly impressive

Wow, that's cool!

So well made! Beautiful trains and good video.

Love your lego trains , I can understand ( as a modeller) how this can become totally absorbing ! ( and it will run outside .)

Incredible work! The fact that you designed multiple stunning train models from scratch is such an amazing feat of design and engineering! And the engineering techniques that went into making it all work on such tight radii is amazing. The only critique I would give, is that it would be even better, if you somehow managed to get the stickers to only cover a single piece, instead of multiple. Lego also used to include multi-piece stickers in old sets, but I believe they abandoned this approach in the 90s. That way the pieces can be disassembled without removing the stickers.

Absolutely love your videos. Your enthusiasm is really infectious and it makes all your videos a joy to watch!

I am an avid LEGO fan all my life, and with that comes the inevitable of watching videos about it on KZfaq. I don't even want to think about how much I've seen... and a lot of it is great. However this is- without a shadow of a doubt- one of the absolute best LEGO videos on the platform right now. The editing, shot composition and staging of your MOCs, and on top of that you two have an exceptional grasp of how to build with and talk about LEGO. Every one of your MOCs shown here is stellar, and I like that they feel like they could easily be officially produced or licensed LEGO sets. Genuinely impressive builds. Amazing work, this absolutely gets my imagination turning for my own builds I'd like to do regarding LEGO trains and railed vehicles. I wish you a million followers and more, this is top-tier work.

amazing as always! more videos please!

Thank you for choosing my railroad for the freight train!

I can tell you're really passionate about this topic. Your enthusiasm is contagious!

I love lego and love trains
