That last run, in scale speed, broke the sound barrier. I'm impressed.

10:56 *_Thomas had undergone a massive remodel in the past year. He was outfitted with the Doc Martin kit and ended up going back to 1885_*

10:56 I was surprised it didn't go back to 1885.

10:54 - *"If my calculations are correct, when this baby hits 8.39 miles per hour... you're gonna see some serious s___"*

It is time for Thomas to leave. He had seen everything.

Doc Brown: WHAT DID I TELL YOU?!!! 11 MILES PER HOOOUUUURRR!!!!!

This is something James May would do for SURE.

You sure it wasn't 88 Mph at 11:02🤔, cause if so, DOC WANTS TO KNOW YOUR LOCATION

You have created the Worlds Fastest Model Train. I’m proud of you son.

“GREAT SCOTSMAN MARTY!” -Back to the future theme intensifies.

Awesome how you put so much effort to find the limits of model trains.

Depends. Bachmann freight loco: not very fast Hornby pacific: unrealistically fast Hornby 0-4-0: lighting speed

10:57 like if you saw the sparks

11:12 I think you hit 88 mph That’s no train that’s a Delorean

Sam: 8.3 MPH, that is faster than anyone can sprint Usain Bolt: *Am I a joke to you?*

Those sparks from the wheels made me think it was going to go back in time. What an exciting video, very impressed with the speeds reached.

Guinness world records would like to know your location

Great fun, you need to get a Flux Capacitor now for the first model train to travel in time.

Never mind Stevenson's Rocket, all hail Sam's Propeller powered Rocket 🚂

Need to see more of that really fast train - perhaps do some load tests and see how quick it would go on the normal layout? Great video as always Sam :)

Sorry sam but usain bolt can run at 22.3 mph. That fact makes the 8 mph look like nothing! XD

Sam, stop putting your trains on steroids jk but I dare you to put a body and proper couplers on the propeller loco and use it on the layout (not at full throttle)

10:03 that sudden cut in power got me laughing lmfao Engine was like : BRRRRR *hits wall* BR- i sleep

I love how so many of us had the same idea from 10:55 :D

Just a cover scheme for Sam to obtain a fleet of super fast model zeppelin railcars

this challenge: *exists* electrical engineers: I am about to destroy this man's whole carrier

"YOU can't Arc Weld with a Model Train" ..... ..... Sam: *"HOLD MY BEER!!!"* 😜

[Footage of APT-E tests at Derby Technical Centre, 1974, restored] That railcar setup is really interesting, a bit like the German Schienenzeppelin railcar, or the Bennie Railplane! Amazing just how quick these models can go, though!

Imagine a normal train going supersonic 😂😂😂

That was flipping epic! I love it when you make content like this and I hope to see more like it in the future. :-)

This is brilliant! Got some Photonicinduction vibes from it with the cranking up of the voltage to see what happens

*The last one would break the sound barrier on a big scale!*

I feel puny that a toy trains faster than me...

Gordon be like: I WANT THIS CHASSIS

I really enjoy your videos Sam I’m so happy I subscribed. You have inspired me to try and collect model trains and I’ll do it all for you dude!!! It means so much to be able to see someone who can inspire me to embrace my love for trains

You could make a Rail Zeppelin with those propellers!

Are you familiar with the triang battle space turbo car?? A brilliant fan powered OO gauge car from late 60s early 70s

7:50 and Sam’s trains presents.. THE WORLD’S FIRST FLYING MODEL TRAIN!

That was just brilliant!!!! And I INTEND to take up your challenge when I have got a couple of but and pieces!!!!! Just brilliant Sam, well done mate!

I can tell you were having way to much fun with this! Great video

My dad did something like this many many years a go he had an old 101 DMU Power car model painted it in a A brown yellow colour and put a mini rocket on the back of it you can imagine what happened next

10:54 almost sounds like a tornado siren lol

If I was asked how fast a loco could go, id drop it off something high and point at it and say "That's how fast it can go"

Hi Sam, Loved the time trials sooner you than me, glad to see John back with his new Dog , All the Best Brian 🤗

Bruv that's NOTHING compared to the super class 47!!! Like if u no wat I meen

Great video! You made a 'model train' travel at Mach 1.1 :)

*Puts two Rocket motors in the tender of my HO scale NYCRR J3 Hudson.*

That was crazy cool!!! I really like how you did that experiment! All the trains were going at an extremely tremendous speeds! Amazing job.

We got an LGB Furtuna Flyer up to 60 actual mph

Frightening! I don't think I've ever been so frightened in my life. At one point it hit a bit of foam and flew over 3inches! Truly petrifying!!

Some people may make fun of model railroading (very few Nowadays) but they obviously don’t appreciate the math and stuff that goes into it. This video was so big brain

GREAT SCOTT.! Imagine the double sonic BOOM!! at 850 mph... brilliant

Look up rail zeppelin on Wikipedia and the George bennie rail car

I clicked watch faster than the train! : D

An outstanding test, Sam. I was indeed impressed how you made the system of the speed, the resistence of the locos, and I'm happy that the little Pocket Rocket didn't burned up. I was also surprised how much volts you putted on the rail chopper, and it got quite scary when the sperks were sparks flew out of the model, and when it almost ruined the track and its wheels, that was just crazy and somehow it didn't went back in time. It was just astonishing how it managed to go more that 10 miles per hour, and that the chopper didn't exploded, and it would be interesting if you once do an autopsy with the engines, like you did with Miles. Anyways, I hope you're having a good day and I'll se you next time!

You are very thorough. Your dedication is most commendable.

You said that 8 mph is faster than anyone can sprint I can sprint 11 mph and I’m 12

This reminds me of the 25v train power supply hooked to the 12v slot cars with high speed gearing. They liked to do burnout and fly off the track

Amazing video Sam I love these types of videos! I would love to see more. Where did you get the railway chopper from?

upgraded rail chopper: hits 850 mph Thomas in hero of the rails: ARE YOU CHALLENGING ME!

"I've never seen anything like that before" I have. On the welding table. You got the voltage so high the wheels and the track started to weld together. If the railcar hadn't been going so fast the wheels would have stuck to the track.

Was going to make a back to the future joke but other people already beat me to it lol, As always fantastic video and very entertaining.

Atlas Trains made an HO Gauge speeder back in the 1960s and in the late '70s I found one new-old-stock in an old hobby shop. It was a de-geared switcher frame with a big motor and a propeller. They gave it a plastic rocket sled body. It was challenging railroading! On an oval with 6 foot straightaways and 18" radius curves you were lucky to go around twice before it tipped going around a curve. In the end the crashes destroyed the thing (wish I still had it!) Isaac Newton says if you make your straight track long enough, you can basically go as fast as air and rolling resistance let you!

So crazily fast it beggars belief. Well done you Maverick. Cheers, Rick the Bulldog

you just gotta push the voltage to 1.21 "jiga"watts

FPV pilot here, Use bldc motors with an esc, they will have drasticly better performance with fraction of voltage. A 2S quadcopter (2S batteries have 7,4 nominal voltage) with 2,5 inch diameter propellers can cruise faster than irl 60 mph

this is an amazing video. have you got any vids yet of other fast locos?

Slow start. Fast speed. That is awesome either way Sam! Keep up the good work!

Haahahah Good onya Sam haha ,, & I thought us ozzies were the only ones to see if we could break the speed record in a billy cart down hill with no brakes hahah. When i was a kid i fitted a slotcar motor into a failed jeouff 4601 class nsw engine i had here and it was literaly the fastest engine i ever had and could pull every carriage i had on my track that used to run around my whole floor and got it going so fast the last cariages used to fall off and constatina'd until the engine finally rolled. Even my sad cranky uncle jim got a laugh out of it... keep up the gr8 vid's m8. Cheers from John in Australia.

Great fun vid very entertaining to watch... Thanks also for entertaining my grandson this past year too... Happy New Year...

The sound of the engine on the propeller driven one reminds me of a WWII siren starting up. Would you think about putting a body on it if you get it fixed up?

I don't think there necessarily is a limit to how fast they can go, it all depends on the type of motor combine with it's gear ratio and the amount of power available. In James may's "The great train race" they build a locomotive with an electric jet powerful enough to push a skate board, much damage followed when they tried to see what it's top speed was.

10:55 Reminds me of Back to the Future part 3 with those sparks on the track at the end.

I thought it was going back in time with the sparks on that run wow brilliant stuff mate

(loco one) "hey you've got to come back with me" (loco two) "were?" (loco one) "back to the future!"

In my misspent youth I fitted a "Jetex" rocket motor to a Hornby railway wagon,. After just a few feet the wagon left the track and bounced across the lawn in a cloud of smoke.

This was a great video. I do have one question though, why did you lift the track up a bit using blocks? I don't see anything wrong with that, its just that I think putting on the floor would be fine unless it has something to do with fire which I completely understand.

I have tried that little stunt before by gluing two drone props to a gondola and boy did it go! However all the rolling stock I have, have bogies so it didn't like the turns too well!

OMG! Sam. Given that train so much speed with big sparks from track and train I thought that thing was going to explode!

Amazing video! At the end, I thought it was going to explode!

I don’t know why this is recommended to me, but I love it!! ❤️

A couple of thoughts: 1) The arcing between the wheel and rail has got to be due to losing contact, even though it would seem to work against going faster, you might try adding additional weight, just for contact (losing contact means losing voltage to the motors, losing power through the spark - that power goes to melting wheel and rail instead of the motor) 2) Using segmented track is ok, I guess, but in the views down the rails, the "loco" seems to be nosing back and forth (hunting or yawing) which could also be contributing to the sparking. Some ways to help this would be to a) use longer segments of "flex-track" (but obviously kept straight), tack them to a piece of plywood, and add the dead section at the end b) use tighter gauge wheels (less gap between the flange and rail) c) use something to damp swaying motion of the bogeys (as you Brits I think would call them, we'd say "trucks") - something to restrict the side to side motion - springs, foam, etc - to help keep the wheels straight 3) Use a longer track and a longer slow-down section - to my eye the "loco" was still accelerating through the speed trap, and if you take longer to speed up, you'll need additional space to let it slow down to avoid crash damage. 4) Don't even worry about aerodynamics, yeah scale speed is 'above the speed of sound,' but that's not how aerodynamics works: to the air, it's still just going 11 mph, which is far from worrying about significant aerodynamic effects. It might go faster to streamline the body, but probably only minimally. Freer rolling wheels, better contact, and high speed motors that can take higher voltage are almost certainly better ways to get higher speed. 5) If you want to go really fast, try the vacuum-ping pong ball method - the Mythbusters did this. There's no reason you couldn't put a piece of track in a tube, put a properly weighted rail car on it, and pull the vacuum. I bet you could be getting TRUE (not scale) speeds over 100mph. Link to Mythbusters video with ping pong balls: kzfaq.info/get/bejne/bp1zo8hlx7DSYIk.html

I had to like this video... Nice one Sam! ..and I can't resist having a go at beating your record.

You could try 750 v DC...when I worked as a TROLLEYBUS operator I liked to "test" them too. Late at night with full voltage (voltage drops with more trolleys running at rush hour) I outran a Corvette (sports car) from a stoplight but 55 mph was about the limit. The overhead wasn't really up to anymore speed...and you have to slow for crossings and switches anyway.

Sam... The endurance run Video was Brilliant. 👍👍 BACK in the 70's.... It seemed like many N Scale Locomotives went at least HALF that fast, bog standard!!! Even in old Model Railroader Magazine Reviews, many N Scale Locomotives were tested OVER 300 SMPH!! 😳😳😆 Love your sense of adventure and humour!! Carmine ✈🚂🚙

This would have been good to do in a loop. I did that for mine. Gradually increasing the voltage. Eventually the corners were a problem. But I was able to move up by 0.5v each time and record the results. These jumps seem a little large.

I love how the train just sounds like it's screaming

Kato sells banked curves for its N-Scale unitrack. If anyone sells HO-scale or OO-scale banked curves, I would recommend getting _that_ (and a lot more room) for speed tests.

That thing tried to WELD itself to the rails man!! What the Gresley Sam.

The train looked like the dolaren from back to the future

When it sparked it totally reminded me of back to the future part 3 XD

That was...AWESOME!!! Reminds me of Back To The Future.

brilliant! and..... you broke the scale sound barrier!!!!!!

Imagine a full-scale locomotive like that one! That ought to be dangerous, but rather speedy all the same! Reminds me a bit of the Rail Zeppelin.

Hi Sam would you ever be able to make a video on how you made that fan locomotive thing i would you be really interested in making one myself.

looks like the motors may want a big capacitor on board to reduce the sparks. maybe some flyback diode too (that would kinda limit the options to just driving in one direction tho). oh. and some thicker wiring.

Dear god that was crazy Sam. Especially with all those sparks coming out like that, I’d be scared to death. I’d hate to do an experiment like this, especially since your track is laying on carpet, but I did see you outsmarted the system, and put Jenga bricks in for supports to the track. I’ve never seen anything the track, and the wheels looking really bad in my entire life like that. Probably the most craziest thing you’ve ever done by far dude. XD

So Scale Speed, You broke the Sound Barrier ! Brilliant!

10:47 When you speed up a video of your model train going on full speed be like.

i'd love to put some brushless drone motors on one, not sure if the tracks could handle the current draw though
