You’re too harsh on yourself Sam, your first 3d printed locomotive should be loved because he just shows you how important it is to find a place to start so you can begin your journey of making your own locomotives. I haven’t started 3d printing entire locomotives yet, but I’ll give it my best over here in the states.

You should always be proud of the first one as that's the one that started you on the path of learning! Be fun to see you go back and do a Mark II of the early ones 😊

I love how you say that Gresly’s rocket is entirely fan powered. (In 2 ways; a real fan and Sam’sTrains fans)

The first model is fab Sam. Captures aura of some hard working industrial monster from the 1800's that was battered and dirty and lived a short life of bodged repairs and oily tea. Absolutely love it.😊

"So Gresley's son hit solid brick and was flattened" jesus Sam that is quite the brutal description

As a fellow 3D printer Sam, and owner of some of your creations, I salute your diligence and patience.

It's really amazing to see how much progress you did Sam. From your first one to your best one. Cheers Jasper & WIllow

some of the best prints ive seen i didnt even think piston rods printed were possible

your locos are incredible Sam! I love how you can see your confidence improve through each successive model! Definitely would say 552 is my favourite! If you're looking for suggestions for future locomotives, why not try (if it's possible) an era 1 loco.. You have The Rocket, but what about the other locos from the Rainhill Trials? how about Sans Pareil or novelty? heck even the cycloped! Would definitely be a challenge!

The gresleys rocket fan idea was done before for james may's great train race attempt two, however it went horribly wrong as the engine, was not fitted with brakes, and then after rerailing it they tested its speed and it derailed at such a high speed it ripped itself to bits, though gresleys rocket has a much smaller fan so it is superior in that sence, so its not top heavy, if only it had a coupling haha As you can tell, gresleys rocket is my favourite, love a wacky idea

Sam every journey starts with the first step and is the learning curve to better things. To get your head around what you have to achieve in order to make 3D printed models is a minefield but with perseverance you have achieved the goals you aspire too. Well done and yes you inspire others in this great hobby.

hi sam. at last a catwalk of sams unique models starting from your first build upto your present build. you should always be proud of your first model because that led to your present day models well done

I can see there’s real potential for progress. With the pace of technology the quality will continue to improve in the years ahead... many more will all be making our own models. Who needs Hornby, Bachmann, Dapol and the likes?

And I just designed and printed 2 HO flat cars. Then I watched the two videos with your engines in them, which is an inspiration to try to do the same. Take pride in that first engine you made. The first is always a prototype, and one you learn from. Love them all as you showed them, and I think I want to do it as well. I did the flat car, because I like flat cars, and it was a good start to try to make something that worked the first time. It also cost me about $20 less to print it then buy one, but paint is not my strong point. I like you masking you did on the handles, and I might try that. Feel pride for what you did, and let your chest swell. Job well done on something you can't buy.

I agree. You have to start somewhere. A loco designed out of your head. I think that's brilliant.

Hello Sam, have you heard of the GWR Garratts? They were 2 proposed designs that never came to fruition. One is a 2-8-0+0-8-2 (using 28XX chassis), the other is a 4-6-0+0-6-4 (using Hall chassis). With both chassis being readily available in RTR, you can combine 3D printing (for the body etc.) with RTR to create these 2 very unique models.

Sam, Thanks for sharing! Your first loco is a neat proof of concept; you should be proud!

It's really amazing how far your 3D printed projects have come. I remember when you teased the prototype as an idea you were working on before you knew it was possible to make a fully 3D printed loco, I never imagined it would turn into multiple proper models! I think my favorite is either the Manning Wardle L Class or Old Coppernob personally, but they're all fantastic- even the prototype 4-4-0!

Even though I've been watching the 3d printing videos since the beginning, it's astounding to see just how much progress Sam has made

Really impressive modeling skills. This video really highlights the whole point of 3D printing: making things you simply cannot buy. I think the main negative is that you can see layer lines in several of your models. Some of that is extrusion issues, but mostly it's an unavoidable limit of FDM printers. Someday you might consider getting a resin printer. They're a pain for a variety of reasons (fumes, the care you need to take with residual resin before washing), but they're really, really good at fine detail. Even the cheapest ones. They also tend to have small build volumes, but I think the models you're printing are well within those limits. It's only the late, really large articulated locomotives that would be too big for most resin printers.

The G E R looks beautiful. I'd like to see next you do some 3D printed '0' gauge models.

I would quite like to see you make a Lancashire & Yorkshire Class 23. A ready to tun model has never been made, whilst it has a large saddle tank and inside cylinders, so I imagine it would be quite easy to make and add weight to make it pull better The Class 23 were rebuilt from Class 25s. They literally removed the tender and added a saddle tank and bunker, so if you wanted to you could modify that into a Class 25

Your own take on a not-ludicrously-priced Caledonian 812 would be really nice to see.

I'd have to say old coppernob is my fav loco you've done. It's so cool to see a modal of these old engines.

They all look amazing and the best part is you made them from scratch. Well done Sam. Martin. (Thailand)

Greeley Rocket kinda reminds me of the push along prop thing Triang did back in the day!

All the models are great they look good and they run well, certain companies should take note. Great videos Sam.

Received my 2 packs of Sam's Trains era 1 wagons today. Very nice, Thanks!

I love ur work for the 3d model trains. I wish I was creative like u brother. Keeping being awesome

The prototype looks good I mean even real locomotive designers have designs that failed you got to start somewhere and it's a heck of alot better than I could do

I have an idea, for a 3D print. "Uncle Fredrickson's Tender Tank". An 0-6-0 Saddle Tank with it's coal bunkers between the tank and cab, an open cab with 2 rotating gates at the back so it can be used as a shunter, or a tender engine (Gates flush with the back of the loco for shunting, and flush with the sides of the cab for tender). It would have one of those HO/OO scale couplings, but is also equipped with a tender coupling underneath.

Excellent work there Sam I would be proud all of those locomotives and cherish and be proud of your first effort cheers from down here in New Zealand

Got an idea for you Sam: a Midland Railway 115 class, also known as a Midland Spinner. It’s another NRM loco that I don’t think is professionally manufactured. Maybe when it’s back on display you should take a look.

Very nice work. You’ve come a long way, but be proud of all your locos and rolling stock. They may not be as realistic or perfect as you desire but this is oo gauge after all. And from Gladstone on, it’s hard to be critical, you did very well on them. Gotta say old copperknob is my favorite. So unique. Keep it up Sam. Your videos are loved by me and my family.

I have a suggestion: The Blue Circle Traction Engine! It’s a very complicated design, so it could be a fun challenge!

I don't know about favorites, but I'd be very happy to have the Gladstone or the 552 on my layout! They look great!

Great work! Love to see your designs printed on a resin 3d printer!

Hi Sam. Would love to see you 3D print an LMS Beyer-Garratt. Now would surely be the ultimate challenge for you. Paul. 🤩

You should be proud of your first loco you had never done anything like it before and you learnt from it and got better

Nice to see someone new having a go at scratchbuilding... I particularly liked your GER 0-6-0 and was impressed by the good running.

Don't be too hard on yourself. They are fantastic! I live in York, so know the engine well!

I love that GER loco, the blue liveries are beautiful, and you’ve had a really good go at it. I think you’re being too modest. I’ll buy it off you!

Make a model of the LNWR ' Special ' DX 0-6-0 Please, they're an underrated and unknown goods loco and they're beautiful!

Sam, all the models are beautiful, including the first one. Your progress have been astonishing. Can I request you to please make a 3D printed running model of Darjeeling Himalayan Railway (DHR) steam engines?

Best channel on UTube ! Sam provides information, details, insight, opinion, comparisons, AND entertainment. I will be SOooo lost if he stops ! .

I think that both Coppernob and the 552 look great! My preferred one is the 552, mainly because of the smart livery. I'd be more than happy to have a loco similar to these in my collection. I genuinely believe that they can compete with professionally made ones of the post 2000 era. And they very definitely look better than my two locos from cheap Märklin starter sets from around 1980. So now, I'm just waiting until Sam's trains trains starts mass production. Edit: what I meant of course was Sam's trains' trains, the trains from the Sam's trains KZfaq channel 😉

Great video Sam! Love seeing how you've improved from that first design, but even that was an accomplishment, if I had to suggest an engine for you to try create, maybe try out the L&YR Class 24? Keep up the good work!

You should try making an LBSC e2. That would be pretty cool to see.

You should be proud..each step is part of a learning curve....I liked the yellow 040 best...keep going Sam

honestly I think the Gladstone is my favorite! but all of the models in the video really show your progress in this endeavor.

There are actually 3 L class engines in preservation, 2 are at the Middleton railway being sir Berkeley and Mathew Murray with Winston Churchill at Birmingham

Sam they are all good but they are getting better and better. Good job

We've followed all of your 3D builds Sam and once you had it going with the Gladstone they all have cracked us up. Admittedly, the Furness #3 still is our favourite as well but the 552 is coming in very close. Especially its blue colour and all the details are spectacular. 3D Printing generally has reached a point where factory standard locos and rolling stock have become attainable as we have seen on another channel. Tonnes of online sellers of 3D files for modellers are available now for just a few dollars per download, or even for free. E.g., we wanted to have catenary but Märklin's own are extremely overly expensive. We downloaded the necessary prototypical 3D files and had them printed for just a fraction of the price. It is time that manufacturers should be getting very worried perhaps... Cheerio.

Hi Sam, great video. Gladstone is my favourite. All the best. Carl.

Beautiful work. I'd love to have a train as nice as that GER 552. I got myself a 3d printer last week and since then I've been pondering if I could print a train. This is very encouraging.

Wow, great job !

You are amazing at what you do and I'd love to do what you have done someday! I'd love to see you try and pull off designing something like the L&YR 29 experimental Mogul, the 5AT, or the 'Q1 Pacific' someday!

The last loco is the best one yet. I can't wait to see what your next loco would be.

Wonderful work.

Hi Sam, great video, it's amazing how far you've come with the quality of the models. I'm sure that greater advances in quality will be achieved in the next few years by the improvement of both 3D printers and the materials used, giving a much better finish at conception. It would have been nice to have seen an example of the construction and assembly of one of your chassis, also the various parts used both purchased and 3D printed. Perhaps another time? Regards Barry.

U have done a good job on all the locos u done

wow what a nice video, this really shows what you can do with persistence and dedication. Something that I've found out recently regarding the manning Wardle L class is that there's 2 others preserved, one being Matthew Murray on the Middleton Railway In storage after its boiler ticket expired in 2021, and the other being Abernant on the Great Central Railway undergoing restoration as of February of last year.

So glad you made this video, as it gives us a great look at your progress over time. Your first loco was already something more than most people could build on their own, but my goodness have you improved! Awesome work, Sam!

Awesome video Sam's trains

Impressive 3D prints. I love them all. I'm going to have to try to make the rocket engine. No matter what you think of them, you did a great job. You have to start somewhere.

got some of the coal wagons delivered today, they are amazing sam jeep up the amazing work ☺

I love them all but as a fan of Stephensons rocket Gladstone is my favourite well done all round sam

Great work! I'd like to see these locos on display at a model rail show along with demonstrations of CAD use and 3D printing

Gladstone is my favourite, looks great and goes well

My top 3 favorite of your 3d are Gladstone Old Coppernob And the 552 The others are also really cool as well

Great job on the L chrichill Sam ! , id buy one !

The Great Eastern locomotive is an absolute classic design, and a brilliant model to run on a regular British layout.

I've been designing and 3D printing a garden scale tank engine over the course of this year, and have found the big strength of 3D printing is being able to easily iterate on parts that weren't quite right the first or second time. Rather than sanding, I've had best results splitting up parts so smooth flat sides can be printed flat, and enabling ironing in the slicer. It makes the print take longer but can dramatically reduce post-processing.

Last summer on the first of fifteen days of BritRailPass took an early ride to York entered the National looked at my left and at a distance the first I catched was the Gladstone so I yelled to myself Sam's Trains!

It is amazing wot you do sam thankyou

Seeing these 3-D printed locos is really starting to motivate me to make my own custom models whenever I decide to get back into HO/OO gauge engines again. As for potential suggestions, I might have some unique locos. I’ve actually done some research and as far as I know, no major manufacturers ever produced any of these locos here. -The Haydock Foundry Well Tank Engine (0-6-0) -KUR ED1 Class (2-6-2) -GER A55 Class Decapod (0-10-0) -BR 11001 Diesel (0-6-0)

That prototypee could hold a candle to an early Rovex, in any case, you were learning and evidently have.

Great video Sam

The FIRST loco actually look like upgraded implementation of Iron Duke.

That’s quite a good locomotive, Sam!! The only thing is that it’s a H0 rather than a 00!!

You can help the weight issue by using heavier filament or adding tungsten beads.

A marvelous effort

Great videa, great content, great models

If you're looking to do a larger engine then GWR no 111 'The Great Bear' would be neat. It uses the same diameter wheels as a Castle so they would be easy to get. Either that or a GWR 'River' class, an elegant early 2-4-0 design, would look great running alongside your City or Dean Goods engines.

1950's scifi themed, something from the buster crabbe era buck rodgers or flash gorden, it would be nice to have a couple of rocket ships running round.

I'm a big fan of Gladstone, I hope to see a RTR model of it at some point *EDIT* Ah yes a suggestion I have is a very fun locomotive for you to build: the Y10 0-4-0 "Super Sentinel" as seen on the Wisbech and Upwell Tramway

You seem to be a master at model making.

Interesting to compare these to the 3D resin printed one. Perhaps one day we can print metal with the same amount of detail.

Another great video - very interesting to see the progress made on each model. A model suggestion: how about Thomas Shaw Brandreth's Cycloped - though getting a motor inside the horse might be a bit of a challenge! 😝

Old Copperknob is certainly a beautiful model. It’s detailed for an early locomotive!!

I love Old Coppernob.

You can be proud of what you've done, many looks very good. Imagine what can be done with fine resin printing... Also you could have showcased these locos with your own rolling stock ;)

Courage mon brave! You've taken me right back to covering my school boy bedroom in white plaster dust and my first few (failed) attempts with the Linka OOscale model building moulds. The branch line to mainline success is chossed - up with missteps, shall we say. Ee bah gum lad wilt tha juss luke ow far tharve come in a few short months! I'm going to dig out the Linka sets now and see if it was my impatience or if I'm simply crap at it.

Ive been looking at 3d printing diesels and electrics, my First project Im going to do is the Class 599 Tyne and Wear Metrocars once I get my Ender 3 Neo. Good thing is with Electric and Diesel locos is that most bogies are either available as spares or able to be easily modified from spares

Good video here Sam, some of those models do look very good, since I don’t have any 3D printing equipment yet the only ways I have made models is by either buying kits or taking an original made model by a manufacturer and doing modifications to the model.

Haha Sam don’t let anyone in the blackcountry know you said they were in brum, you’ll never hear the end of it 😂 I was sceptical in the extreme about the coupling rods but I’ve followed your lead in doing an 0-4-0 as a freelance saddle tank but did it outside frame outside cranks using class 08 wheel sets as practise for a GWR 4-4-0 3521 class, and yeah, works! Before that I’d only modified donor chassis to suit 3D printed bodies (changed wheel sizes, cut and shut) or done a loco chassis but with old tender drive units, but you inspired me to do something 100%, well except the gears; the wheel set already had a drive axle and I hand a screw for the motor so…

Hi Sam, You have done well,, more power to your elbow, keep it up all look good, All the best Brian 😃

Wow your 3D Printed UK Steam locomotives look phenomenal. I need my uncle to make me some locomotives like these because I don’t have a 3D printer! :)

Awesome vid sam, very impressive!

Amazing Journey Sam. The Great Eastern Livery looks great. Some challenging ideas for future projects. Great Western Broad Gauge Iron Duke 4-4-2, This will mean 3D printing Brunel style bulk road track with longitudinal sleepers and cross ties with maybe normal rail clipped in. A big challenge but how great would a broad gauge train be !
