My favorite thing about watching Sam make 3D printed models is that he's cognizant of his past complaints during reviews and does his best to make sure he's consistent with his important points when he makes his own trains!

Hiya Sam: As I remember from traveling British rail in the 60s, all the toilets I encountered literally flushed (Well....'dropped') directly onto the tracks. You could actually see the sleepers blurring past beneath the hole. There was also a well remembered sign above warning you NOT to use the toilet whilst at a station...!!!! I'm guessing the result was a kilometre long 'splat' along the tracks somewhere out in the countryside...Just FYI.... Great video as always! Cheers

From my experience with 3D printers I suggest to print the sides of the body separately, flat on the side on the printer bed, and glue them together when all 4 sides and the interior with the underside is done. It is how I did some of the houses/sheds for my daughter's horse ranch and those looked much better with this technique, avoiding the issues with stringing and bridging, the flat surfaces on the sides looked much better when printed this way. Hope this helps. Keep up the good work, I enjoy watching your videos.

Hey Sam you should design some egg vans and watch them run better than Dapol’s

You're at the level to make a simple diesel shunter or box tank I think - assuming you designed it just to fit onto a pre-existing chassis anyway. Scratch building either is definitely also not beyond the range of your abilities if your maintenance skills are anything to go by. So definitely worth the challenge, just don't go in over your head.

Excellent, well done. The rake of coaches with the small “baggage” car looks fantastic. Small steps then giants leaps, this was a big leap but most importantly you have raised to the challenge and enjoyed it. Looking forward to the next production run. Well done Sam, all very best Marc

Sam: I’m not at the level to make a loco yet: 20 years later Sam’s trains has produced over 4000 models and is now coming on bachmans radar

Very impressive Sam! You’re gettin’ better and better! We’ll make a model manufacturer of you yetL

In a guards compartment you can expect an emergency brake with a vacuum gauge above it as well as a seat, spare coupling and vacuum pipe and somewhere to store flags. You could even go as far as putting a guards bag on the floor! Hope this helps, nice video.

Hey Sam, May I suggest that you alter your 3-D prints by moving the NEM socket inward more so that the coaches do not have such a glaring opening between each other.

Correct me if I’m wrong but didn’t they also use the break compartment to store baggage and luggage too? So I think racks for boxes and bags would be a good addition. But ultimately it’s your design so do whatever you like. Stay safe & have fun Sam!

I'm telling you, strongly consider making them to order! Maybe they are only train set quality, but that maybe good enough to get going! The only thing wrong really is the coupling distance. The passengers will have to long jump to move from car to car!😁

The most luxurious coach toilet I’ve ever seen, usually there is just enough room to walk in shut the door and sit down!

I love 3D printed stuff especially hornby it’s so cool that u can do this great video :)

Suggestion: Make a long-distance train with coaches that have sleeping cabins and a galley. This also means that the coaches would need to allow passengers to get from one coach to another.

This video was very well done as was the project. You should be extremely proud of your efforts. Looking forward to your next video.

Absolutely outstanding 🤩👏 well done Sam, it was a joy to watch and the outcome was fantastic! You have a real talent there!

I can imagine, April 1st 2022, not Sam reviewing the latest model from Sam’s trains…

very impressive. i have enjoyed your 3D printing/producing videos quite a lot. its great to see the thought process that goes into them from start to finish.

These turned out amazingly, good job! I have another possible challenge if you would like to try it; designing an original class of steam loco that doesn't exist in real life. You can use the wheels, rods, and mechanism from pre-existing models to make that part a little easier, but you get bonus points if you print out your own gears and only source the wheels, rods, and motor from a pre-existing model. It can be either a tank or tender engine, or you could design and print one of each for a bit more challenge.

These coaches look great. Great job sam

I love the variety of your channel, all your video are put together so nicely and are always fun to watch!!

Wow. I am very impressed. You have done a great job. You have inspired me to take up 3d printing. If I might suggest a challenge: A horse van. Hornby had made one which is no longer available. The challenge would be to make doors that open on each side to become ramps for the horses. Could also have a half interior wall between the two stalls. The hinges might be made from length cut from a paperclip then glued onto the door. Are your larger coaches available for purchase? Are your smaller coaches available for purchase? I thought the smaller coaches could look very good with the Stephenson's Rocket. Thanks for a really great video.

Totally brilliant Sam, Your a natural at this. I wouldn't have a clue !!! Keep up the fabulous reviews and training sessions. Cheers, Rick the Bulldog.

Love the 3D coaches. The design feels very Victorian. Hope you print more coaches so that you can make longer train lengths:)

Hey Sam, Seeing how great your 3D printed rolling stock I had an idea that you create a custom Sams Trains coach, brake van, wagon and sell it on your online shop. All the best! -Oliver

Nice work Sam, your rake looks great! A couple of suggestions if I may: 1. Reduce the size of the windows - I think they are too big for that style of coach. 2. Incorporate a horizontal dividing line/strip into the coach-side design (if you don't already have one...) so that it is easy to mask off, then paint the coaches 2-tone!

They do look very good :) I feel like they seat blue seating. Regarding the guard's compartment, they would have been used to carry goods, and while guard's vans had stoves, I'm not sure about compartments in coaches. A locomotive would be a challenge, but I suggest using a donor chassis rather than designing your own. Steam boilers would probably print best oriented upwards, and glued onto a separate cab to improve model quality.

Great video and yes they look great. Please keep this great series of scratch building coming. 3D printing has come a long way. All the best

Thanks Sam. Your ambition for this was wonderful.

Well done Sam, brilliant video and look forward to seeing you design and print an engine of some description

I always enjoy watching your 3d protect and looking forward to see what you do next.

Very good. There are three rules you need to abide by. 1. Make sure the room you are in is well ventilated 2. Wear a pair of plastic working gloves so you don't get any paint on your fingers 3. Wear a pair of goggles; you must protect your eyes while working I've got this on one of my model railway DVDs.

Well done Sam, you can see your getting more confident 👏, looking forward to see what you come up with next.

Thank you for showing us. It is very inspiring to see you develop your skills.

These look really good! For the brake coach, I would suggest fitting a door between the corridor and the guard’s compartment so they can walk up and down the train en route

These are excellent coaches you’ve made Sam, your making great progress in your 3D printing department. When your prints come out with all the stringy lines and what not a small file and fine grit sandpaper is really helpful for getting rid of all that hope this helps!

Excellent, thank you for taking in my request. :)

That was a lot of fun to watch, Sam, and I like the result. When you were worried about the satin varnish, my immediate thought was "If it doesn't work, get a rattlecan!" There are plenty of spray cans of varnish -- matt, satin or gloss -- available from both model and art paint suppliers. A tip: use acrylic rather than an oil-based paint because it doesn't yellow nearly as much. But since your varnish worked okay, you needn't worry about it. 😁

When you've got a bit more experience with 3D printing, could you make a GWR (originally Avonside) 1101 'Dock Tank'? I've got copies of the drawings and a 7.25" gauge model of one of these if you want pictures, and, of course, if you want to do this challenge!

I am stunned by this. Never thought I’d see Sam making a line of passenger cars like this, but I’ve been proven wrong in the biggest way

Very impressed with what you've been doing with your 3D printer. For a first attempt the coaches are a very good effort. A few suggestions: 1) The coaches look like they're riding a bit high. Perhaps recess the chassis a few mm for future efforts. Looking at some of my Hornby ones that's what they've done. You could check the height against a platform. 2) Make the interiors a separate slot in piece which would make painting them easier, especially if you wanted to make some parts such as the sink, toilet or seat cushions a different colour. 3) If you want to take them up to another level design them to allow fitting of an LED light strip. 4) Your chassis would also work well for a parcel/CCT van. N.B. How long are your coaches? Is the length dictated by the size of the printer bed? As a comparison my Hornby LNER teak lavatory coach, which is fairly short, is 210mm. Is it possible to print diagonally on the printer bed if you wish to make a slightly longer coach? Print suggestions: - How about a 3D printed platform? You could also add things like benches, bins, flower beds, ticket/vending machines, fences, luggage trolly, etc. Then try some buildings such as workmans hut, signal box, a branch line station building, etc. Perhaps try making slot together pieces like Linka so you can make a variety of structures using the same parts? Great video as always keep up the good work!

Well, I'm impressed! These look very good, you've certainly developed a real proficiency with the 3D printer, and you'll soon be extending your airbrush skills to the weathering of freight trains, spraying stains and rust over oil tankers, and imitating coal dust and oil patches and drips around the undersides of your steam locos. Don't forget the grime around the exhaust grilles of your diesel fleet either. Great work, Sam!

Those models look incredible Sam, here's an idea how about making decals for some of these projects like create some logos, signs or name plates etc with using things like decal/transfer paper.

Wow!! These are amazing

Those coaches look neat, i'd be happy with them, they're functional and certainly do look good, even though we all know they're 3D printed, i love seeing Sam's confidence soar when he produces these 3d models, i'm in awe.

You should make a mail van to go with those coaches. (4 wheeled one to be precise)

Well done sam. They looked good throughout the whole design and running process. I enjoy your channel and have recently subscribed. Many thanks. Keep up your excellent work.

Nice idea of making little bits on the ends of the attachment points for the bogies to prevent body wobble, here in the US where most of our rolling stock uses bogies we use what is called a "Three point suspension" we tighten one bolster screw on one bogie to where it can freely turn but not go up and down but the other bogie is loose enough to move in all directions, this allows the car to not wobble but still give it enough play to make it over gradients and rough trackwork.

Great video, the coaches looks pretty good. Maybe add some lighting and some figures inside. But I think you have done a really good job. Next. Challenge 3D print a station or a engine shed? Keep up the great work

It's actually astounding seeing someone make their own model trains with a 3D printer, it makes me want to give it a shot at making something like it! All in all, incredible job Sam, keep up the amazing content! Also, here's a suggestion for you're next video: Try to 3D print a model of the "Furness Railway K2 Locomotive" they are rather underapreciated and don't have any model of them neither by horby, dapol, bachman, lionel, etc. So i would really like to see you give a shot into making one. Fun Fact: The K2 Locos was the base model for Edward from Thomas & Friends.

Very good job Sam. They look fab.

Amazing video! I loved it

You are very good at this 3d printing. I love these. Awesome video. I really need myself one of these printers.

Enjoyed the video, Job well done.

These are awesome they look really good

In a word BRILLIANT !!!!!!!!!!!!!!! Cheers Greg

Very nice coaches you’ve made there Sam. All you need is a 1st-3rd composite or a full first class coach and you’d have a fine train! It looks a lot like something you’d see made for a pre-Grouping railway too. If you ever want to try taking on a coach with a flatter roof, I’d recommend you look at the North British Railway’s Holmes-designed non-corridor stock. They’re wonderful coaches that pull off the boxy look like a treat. Well done again, can’t wait to see what else you make in future.

Great video, super useful!

Absolutely fantastic Sam, I know the feeling of producing your own 3d printed parts, so your carriage project is brilliant. How about a replacement body for a hornby 0-4-0 loco, then you’ll have your own complete train. Well done a great project.

I love your 3d printing Videos! They're simply fantastic! You should make some real rolling stock next! Maybe some modern trains?

Dude this was an awesome video!

Once again, proof that you CAN in fact, design and make yourself more competent than some larger companies out there. Giving more weight to when you declare a coach or wagon has terrible wheels, couplings, tooling, etc... LOVE your 3D printing videos! Keep up the great work! :)

WOW they look aweome

Railroad engineering, design and production. All accomplished with aplomb. Sam, you are very talented and I for one am grateful you share your works. Thank you so much. One thing - at the risk of sounding critical - I would have put the bathroom at the other end of the train (please be laughing at this).

What an amazing job you did Sam I would buy those lol love your 3D making videos

Without reading any comments here! I want you to know I have been doing 3d printing for 5 years have done many of my own designs and have had my share of compliments. And I think it's time. You should be Extremely proud of the job you did. It is no small feat going from design to print to a in hand model! My opinion Great Job!

Great job Sam, really enjoyed watching the project. the coaches look really good!

They look really good

Really brilliant and very inspirational stuff. I'm really going to have to find space for a 3D printer in my flat somehow. Your next guards-van coach is going to need lookouts, though. Either duckets on the sides, or a 'birdcage' on the roof. Birdcages were common until the early twentieth century. Glazing the karzi should be easy. Cut a piece of tissue, and fix it on the inside of the 'glass' by generous application of Liquid Poly or Mek-Pak. If you use ordinary two-ply Kleenex or similar, separate the plies and only use one thickness. Works a treat.

Your first steam locomotive was a very attractive little model. Good luck with the coach challenge!!

Sam the interior details of those coaches is incredible! Very nice work all around. I know its not your style but you gotta give yourself more credit hah =)

Well Sam, now you have a proper carriage for your Railway Children set! Great work Sam.

Very cool video... well done, that man... 👍👍🙂🙂

Sam, you are never boring - great job

wow that looks really cool..Getting the hang of that printer huh!...Sam loves his rounded edges..lol......Great challenge i think you succeeded nicely! Watching you create in that program was oddly satisfying..Looks pretty straight forward.

Very impressive Sam. The interiors look great, the paint isn't bad and the fact you did the glazing was just over the top cool. Loving this series.

Really cool!

thoses coaches are BEUTIFUL i wish i could do some like you :D

This sounds like a great video sam, also I had a blast at the nrm

Great video, Sam. I'm new to your channel; just having a look and enjoying the variety of what you offer. Your foray into coach building reminds me of why I enjoy model railways and miniature wargaming: variety and DIY adventures. Thanks for uploading, and all the best from Aotearoa New Zealand!

Long and boring? Not at all! As of this Christmas, I am the proud owner of a Bambu Labs 3D printer. Also as of this Christmas, I have resurrected my HO trains from 50 years ago with an eye to sharing them with my grandkids. I also know SketchUp from designing furniture and remodeling my home, and I even have a nice airbrush setup. And now, in one video, you've brought it all together end-to-end. So we shall see whether I can achieve results comparable to yours. Thanks very much for this fun and instructional video!

Excellent !!

They look really nice

Wow.. I mean WOW! I really didn't realise how much attention you put into the detail. You really went above and beyond and completely exceeded my expectations with this challenge. Indefinitely can say the this challenge has been well and truly passes, well done Sam.

You have come a long way with 3D printing. Very well done, Sam!

A amazing video Sam ! . I loved watching the process of you designing and making these coaches . I would even buy these !. Maybe you could design a rake of different freight carriers. Such as tankers , low loaders and shipping containers etc. Love the videos !

This is awesome. Now we can print Victoria and Helena. Btw, this is an awesome design.

i love them!

I know that on the Mk I or Mk II brakes the guard's compartment had a small desk with a little rack for things like flags and possibly lamps. Maybe you could also add a few home comforts like a stove and radiator for those long trips?

Wow! Great job and you never know 'Sam's Models' in the future? Anyway, a good step to building a loco I would suggest is a compromise and build the GWR Steam Motor Coach, a good reference is preserved Motor Coach 93 at Didcot Railway. Great video!

love this! I think I might have to follow your example one day :P

Well done, you are a clever lad!

I ❤them you did a great job with those coaches.well done. Sam

They look really good and 3D printers really intrigued me from someone who went to school in the 70s and never had computers or anything like that in my day I think they're brilliant

hey sam great vid keep up the good work

Good job. They look great. :-)

Great work Sam you can only get better.

Looking superb! You can now make your own 'Warflats'... A couple of drops of black added to the main colour in your airbrush, will tone down any very bright colours.

Nice Sam looks great! They look like the ones which have the and metal wheels
