[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!
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!
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
too me it sounded like my fpv race quad taking off . Speaking of which , why not use high kv brushless motors next time for the train. I'm sure bangood has such things available
"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.
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: ua-cam.com/video/87Cpe4bJn0U/v-deo.html
Thanks a lot for that - yes you're right - if I were to do this again, I'd have multiple wheels picking up - just one per rail is nowhere near enough! The streamlining would definitely be useless too - I have seen a lot of comments suggesting I do it though ;) Thanks for watching - Sam :)
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!
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.
Speaking of toy trains. Most HO modelers consider Tyco locomotives toys but, what's so great about them is that they're easy to modify. Take some Brass detail parts and you've got a neat looking heavy duty engine. As for your challenge I don't have a camera or the skill to make a super fast model. But what I do know is, if you were to take two gears, one large and one small, Put the large one on the armature shaft and place a smaller gear on the wheel axle it would make it go faster.
That sounds great - I have heard good things about tyco! Yes that's true- but gearing will never be as efficient as propellers - you'd need a lot of torque to get that out of a geared system! Thanks for watching - Sam :)
WOW! Sam, I've never seen model 'anything' go that fast. And, as a 1 1/2 inch to the foot live steamer, I've been asked, to many times, how fast with this thing go? I heard you say that at the start of this video, and I started to laugh to myself. I run a coal fired 4-4-2, with 10 inch drivers(scale for 80inch). What I usually tell people is this, "It will go fast enough to scare the hell out of you"! "And thats with you on it"! Great video.
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 ✈🚂🚙
Thanks very much mate - wow that's crazy stuff, was that because they weren't gearing them down enough due to their size?? Thanks for watching - Sam :)
Well that, and the Slot Car Motors that Arnold and Trix used were incredibly FAST. There was no room and no brains, so they simply fixed the Worm Gear from the Motor STRAIGHT to the Axle - with no thought of reduction. 😖 It finally took the Japanese (KATO) to finally sort how to make a N Scale Locomotive run properly. They used 35v Motors, so NO Hobby Transformer could ever reach its top speed! Oh and even in the late 80's, they ran like fine Watches. Skewed Poles, Precision Can and Coreless Motors really revolutionised N Scale!! 👍👍
To validate your measurements and results you need to post the voltages being used. Off camera you're making voltage adjustments so we have no idea how fast you ramp up to the target voltage. I'd recommend having a switch that interrupts power to the track while you set your output voltage to the desired setting, then switch on the track and see what happens. You'll probably get even higher speeds simply because the train is running at its intended voltage the full length of the track. It seemed to me like in some of the earlier tests the train voltage was not at an instant voltage but the result of you turning the dial up till you get the speed you want. However, if you DON'T want to incorporate a switch you could put tape on the Variac and mark dial position at specified voltages to help you get the dial up to that voltage faster. But I think the best way to go would be to have a switch turn the track on at a preset voltage. Reading wiring and voltages - that capacitor could be the weak link. If it's rated for 35 volts, exceeding that voltage COULD have spectacular results (catastrophic failure). The sparking on the track could have been the result of the capacitor beginning to break down. But I don't know that for sure.
Yeah you're right there Pete - it was just a bit of fun really, I knew I wasn't being dreadfully scientific. I thought about trying a switch, but decided the sudden voltage surge might ruin everything! Thanks for watching - Sam :)
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
Thanks mate! Those sparks certainly were quite scary! It wasn't anything too aggressive though - there's no way a spark from that would cause a fire within the time it'd take me to stamp on it! ;) Yeah the state of those wheels and the track was crazy - never seen anything like that either!! :O Thanks for watching - Sam :)
Making even faster local that goes so fast the quickest way to break is via parachute from the back so it can't have any carriage attaching features so it can automatically detach to get out so the parachute can be deployed or all cars have brakes built in
Ducted fan would improve your results. The only thing in the device capable of creating that big of a load would be the electrolytic. Was it's voltage rating enough? The magnet wire in the motors would melt before the track would arc weld. Wheel hop probably played a roll to.
Yeah you're right - I really should try this again with the ducts! They were only 16v caps, as I originally only intended to run them on 12v, but I'm glad I didn't upgrade them - it was much more dramatic this way! ;D Happy New Year, Sam :)
Arcing happens when the current on the inductance of the motor is stopped because the wheel does not touch the rails continuosly. Then the current in the inductance can't stop and will make high voltage and thus arcs. Using digitally controlled motors combined with big capacitors the arching problem could be solved. On this relatively short track it is not only about high speed but also about acceleration. Metal on metal has not enough friction for big acceleration. If we accept low acceleration then with regular trains the power of standard engines would be enough for high speeds but the gearbox should be changed to have less traction but higher high speed. I would try building a loop with superelevated (bent) turns and use a modified gear ratio engine with digital control to achieve high speed. Maybe one day I will try and also video it.
That was a cool experiment. Making a custom locomotive with propellors like that makes me think of the experimental locomotive, the Schienenzeppelin. Which was sadly scrapped 80 years ago, by the way. But watching those sparks jolting out was just awesome overkill.
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.
@@SamsTrains Have you come across slot car racing (Scalextric) ? One branch of the sport/hobby is slot "Drag Racing" the top speed of the fastest 1:24 scale cars is an actual 140+ MPH at the end of a scale 1/4 mile. Thats zero to 140 MPH in just 55 feet. I wonder just what sort of speed could be reached at the end of a longer track. www.hotrod.com/articles/hot-rod-anything-140-mph-slot-car-drag-racing/
We once made some motors in A level physics and me and a couple of friends decided to get all the power supplies we could find and connect them in series to this little motor designed for 3V. In total it was something like 40V across that motor and the motor did break rather quickly (I have the video if you want to see it). I also think that I can beat your speed with the aid of model aircraft motors that can push a model plane over 100mph real speed.
haha that sounds pretty awesome! Thing with motors is that they can be overloaded quite badly, but it needs to be gradual rather than a sudden shock! Still, it is fun to fry motors ;D Thanks for watching - Sam :)
@@SamsTrains it did run for about 30ish seconds but it was fried after that. All the tape was scortched black, the contacts were black, the wires had melted and a rubber band also wqs charred black and snapped from it
Maximum Voltage I ever feed to my model was 48V. If it isn't for too long time, Motor survive that (but it should be a loco without light, lights die before motor of course)
It's been about 15yrs since I worked in a model shop, and I still remember my managers story. Back in the 70's/80's the train sets didn't include the controller, due to the tax reasons. A man (I believe Indian from his story) bought the set, and connected it STRAIGHT TO THE MAINS! The story goes it ran extremely fast, ran off the tracks and fell on the floor, before bursting into flames.... You hit 60v, UK mains voltage is 230v...... As you said, don't try this at home....
haha that sounds pretty fantastic! Would it really have moved anywhere though, being connected to AC? I will have to find out exactly what happens when you connect a loco directly to 120v/240v - though I expect it would all be over very quickly, haha!! ;D Thanks for watching - Sam :)
@@SamsTrains I assume it would have, but it couldn't have gone far, going by the scalextric method of going too fast. While the Hornby motors do run on the basic premise of the more power you put into it, the faster it will go, but taking about 20x the maximum usual power input does sound too much for them to handle If you do do that experiment, do it outside! It was bad enough seeing you throwing locos towards your computer
I like the Southern locomotive used in the beginning. In America, my late grandfather retired from Southern Railways. He had an HO scale model railway hobby too, I wonder what he would think of these experiments :)
You should make an express running session with Little Miles,the SR 0-6-0 and the ‘’ trackcopter ‘’.That was a great experiment.Keep up the SUPERgreat job!!!-The LMB Channel
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.
Me and my Dad did back in the 95. Took model rocket engines and strap them to a G scale car and cut out back of a LGB Stainz engine. Took it to the convention in St Louis and had the fastest Drag train at the drag race that year.
I think the little 040 could be modified using a performance motor they sell for slot cars. I know hornby's sister company scalextric used to make performance tuning motors to replace the standard motors in the cars. The 040 motor is the same as some found in the scalextric cars.
Cool!!! So does this mean we can have models that look similar at 1:87 scale (HO) but we can also have models that can match the speed and performance of the real locomotive?. I'd love to get an HO Ouigo, TGV or AGV with the exact scaled speed.
All that sparking and arcing was fun. c: The damage to the track and wheels came from that because the electrical arcs are hot enough to vaporize and ablate the metal, which causes little molten bits of metal to splatter on everything nearby.
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!
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.
Wow Sam! What fun! Loved this video. Can I say though, I really think you should be careful welding with model railways using nice burny plastic on nice dry wood and nice burny carpet in the middle of your fantastic burny layout haha! Great video. So much fun to watch. Nice work mate
haha thanks very much Chris! No worries - I took the proper precautions - and the raised track meant that no hot sparks would get to the carpet ;D Thanks for watching - Sam :)

Thanks for watching, Sam :)
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: ua-cam.com/video/87Cpe4bJn0U/v-deo.html
Thanks a lot for that - yes you're right - if I were to do this again, I'd have multiple wheels picking up - just one per rail is nowhere near enough! The streamlining would definitely be useless too - I have seen a lot of comments suggesting I do it though ;)
Thanks for watching - Sam :)
You said that 8 mph is faster than anyone can sprint I can sprint 11 mph and I’m 12
haha yeah! I admit I got a little carried away there ;D
Thanks for watching - Sam :)
Sam'sTrains Yea I enjoyed the video
Hi Sam, Loved the time trials sooner you than me, glad to see John back with his new Dog , All the Best Brian 🤗
Thanks very much Brian, glad you liked that! Who's John?! haha!
Thanks for watching - Sam :)
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!
Thanks very much mate - I was quite amazed by it too!! I thought I'd see more burn-outs than that!!
Have a great day,
Sam :)
Slow start. Fast speed. That is awesome either way Sam! Keep up the good work!
Thanks very much Andrew - really glad you liked it! :D
Thanks for watching - Sam :)
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.
Speaking of toy trains.
Most HO modelers consider Tyco locomotives toys but, what's so great about them is that they're easy to modify.
Take some Brass detail parts and you've got a neat looking heavy duty engine.
As for your challenge I don't have a camera or the skill to make a super fast model.
But what I do know is, if you were to take two gears, one large and one small, Put the large one on the armature shaft and place a smaller gear on the wheel axle it would make it go faster.
That sounds great - I have heard good things about tyco! Yes that's true- but gearing will never be as efficient as propellers - you'd need a lot of torque to get that out of a geared system!
Thanks for watching - Sam :)
That was...AWESOME!!! Reminds me of Back To The Future.
haha thank you!! I'm getting quite a lot of back to the future comments, haha! ;D
Thanks for watching - Sam :)
So crazily fast it beggars belief. Well done you Maverick. Cheers, Rick the Bulldog
WOW! Sam, I've never seen model 'anything' go that fast. And, as a 1 1/2 inch to the foot live steamer, I've been asked, to many times, how fast with this thing go? I heard you say that at the start of this video, and I started to laugh to myself. I run a coal fired 4-4-2, with 10 inch drivers(scale for 80inch). What I usually tell people is this, "It will go fast enough to scare the hell out of you"! "And thats with you on it"! Great video.
hanks a lot Bruce - haha I bet that is pretty scary at speed too!! ;D
Thanks for watching, Sam :)
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!
haha that's great to hear William - good luck!! :D
Thanks for watching - Sam :)
*Puts two Rocket motors in the tender of my HO scale NYCRR J3 Hudson.*
haha!! ;D
@@SamsTrains Yeah, you should see the Rocket Rail Sleds we got on stock in the 🇺🇸.
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 ✈🚂🚙
Thanks very much mate - wow that's crazy stuff, was that because they weren't gearing them down enough due to their size??
Thanks for watching - Sam :)
Well that, and the Slot Car Motors that Arnold and Trix used were incredibly FAST. There was no room and no brains, so they simply fixed the Worm Gear from the Motor STRAIGHT to the Axle - with no thought of reduction. 😖
It finally took the Japanese (KATO) to finally sort how to make a N Scale Locomotive run properly. They used 35v Motors, so NO Hobby Transformer could ever reach its top speed!
Oh and even in the late 80's, they ran like fine Watches.
Skewed Poles, Precision Can and Coreless Motors really revolutionised N Scale!! 👍👍
To validate your measurements and results you need to post the voltages being used. Off camera you're making voltage adjustments so we have no idea how fast you ramp up to the target voltage. I'd recommend having a switch that interrupts power to the track while you set your output voltage to the desired setting, then switch on the track and see what happens. You'll probably get even higher speeds simply because the train is running at its intended voltage the full length of the track.
It seemed to me like in some of the earlier tests the train voltage was not at an instant voltage but the result of you turning the dial up till you get the speed you want. However, if you DON'T want to incorporate a switch you could put tape on the Variac and mark dial position at specified voltages to help you get the dial up to that voltage faster. But I think the best way to go would be to have a switch turn the track on at a preset voltage.
Reading wiring and voltages - that capacitor could be the weak link. If it's rated for 35 volts, exceeding that voltage COULD have spectacular results (catastrophic failure). The sparking on the track could have been the result of the capacitor beginning to break down. But I don't know that for sure.
Yeah you're right there Pete - it was just a bit of fun really, I knew I wasn't being dreadfully scientific. I thought about trying a switch, but decided the sudden voltage surge might ruin everything!
Thanks for watching - Sam :)
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
Thanks mate! Those sparks certainly were quite scary! It wasn't anything too aggressive though - there's no way a spark from that would cause a fire within the time it'd take me to stamp on it! ;)
Yeah the state of those wheels and the track was crazy - never seen anything like that either!! :O
Thanks for watching - Sam :)
Making even faster local that goes so fast the quickest way to break is via parachute from the back so it can't have any carriage attaching features so it can automatically detach to get out so the parachute can be deployed or all cars have brakes built in
Yeah that'd be very awesome actually - but quite advanced for me ;D
Thanks for watching - Sam :)
Ducted fan would improve your results. The only thing in the device capable of creating that big of a load would be the electrolytic. Was it's voltage rating enough? The magnet wire in the motors would melt before the track would arc weld. Wheel hop probably played a roll to.
Yeah you're right - I really should try this again with the ducts! They were only 16v caps, as I originally only intended to run them on 12v, but I'm glad I didn't upgrade them - it was much more dramatic this way! ;D
Happy New Year,
Sam :)
Arcing happens when the current on the inductance of the motor is stopped because the wheel does not touch the rails continuosly. Then the current in the inductance can't stop and will make high voltage and thus arcs. Using digitally controlled motors combined with big capacitors the arching problem could be solved.
On this relatively short track it is not only about high speed but also about acceleration. Metal on metal has not enough friction for big acceleration. If we accept low acceleration then with regular trains the power of standard engines would be enough for high speeds but the gearbox should be changed to have less traction but higher high speed.
I would try building a loop with superelevated (bent) turns and use a modified gear ratio engine with digital control to achieve high speed. Maybe one day I will try and also video it.
That was a cool experiment. Making a custom locomotive with propellors like that makes me think of the experimental locomotive, the Schienenzeppelin. Which was sadly scrapped 80 years ago, by the way.
But watching those sparks jolting out was just awesome overkill.
Thanks Thomas - yeah I've since seen photos of that, very interesting! Yes the sparks made this one much more fun ;)
Thanks for watching - Sam :)
Sam'sTrains yes indeed. You’re lucky your room didn’t catch alight via an electrical fire.
Sam'sTrains You may have killed your metal wheels, railway track and the wiring and motor. But this experiment was definitely worth it.
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"
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.
haha that sounds awesome.... don't go giving me ideas!! ;D
Thanks for watching - Sam :)
@@SamsTrains Have you come across slot car racing (Scalextric) ? One branch of the sport/hobby is slot "Drag Racing" the top speed of the fastest 1:24 scale cars is an actual 140+ MPH at the end of a scale 1/4 mile. Thats zero to 140 MPH in just 55 feet. I wonder just what sort of speed could be reached at the end of a longer track. www.hotrod.com/articles/hot-rod-anything-140-mph-slot-car-drag-racing/
We once made some motors in A level physics and me and a couple of friends decided to get all the power supplies we could find and connect them in series to this little motor designed for 3V. In total it was something like 40V across that motor and the motor did break rather quickly (I have the video if you want to see it). I also think that I can beat your speed with the aid of model aircraft motors that can push a model plane over 100mph real speed.
haha that sounds pretty awesome! Thing with motors is that they can be overloaded quite badly, but it needs to be gradual rather than a sudden shock! Still, it is fun to fry motors ;D
Thanks for watching - Sam :)
@@SamsTrains it did run for about 30ish seconds but it was fried after that. All the tape was scortched black, the contacts were black, the wires had melted and a rubber band also wqs charred black and snapped from it
Mom why is there a blackout? Because Sam's doing another genius experiment . Oh ... can i help?
haha - very sorry about the power cut ;)
Thanks for watching - Sam :)
Maximum Voltage I ever feed to my model was 48V. If it isn't for too long time, Motor survive that (but it should be a loco without light, lights die before motor of course)
It's been about 15yrs since I worked in a model shop, and I still remember my managers story. Back in the 70's/80's the train sets didn't include the controller, due to the tax reasons. A man (I believe Indian from his story) bought the set, and connected it STRAIGHT TO THE MAINS! The story goes it ran extremely fast, ran off the tracks and fell on the floor, before bursting into flames....
You hit 60v, UK mains voltage is 230v...... As you said, don't try this at home....
haha that sounds pretty fantastic! Would it really have moved anywhere though, being connected to AC? I will have to find out exactly what happens when you connect a loco directly to 120v/240v - though I expect it would all be over very quickly, haha!! ;D
Thanks for watching - Sam :)
@@SamsTrains I assume it would have, but it couldn't have gone far, going by the scalextric method of going too fast. While the Hornby motors do run on the basic premise of the more power you put into it, the faster it will go, but taking about 20x the maximum usual power input does sound too much for them to handle
If you do do that experiment, do it outside! It was bad enough seeing you throwing locos towards your computer
10:55 Reminds me of Back to the Future part 3 with those sparks on the track at the end.
haha me too!! xD
You could make a Rail Zeppelin with those propellers!
haha you certainly could!! xD
Thanks for watching - Sam :)
brilliant! and..... you broke the scale sound barrier!!!!!!
Thank you! haha yeah that was crazy! ;D
So Scale Speed, You broke the Sound Barrier ! Brilliant!
I like the Southern locomotive used in the beginning. In America, my late grandfather retired from Southern Railways. He had an HO scale model railway hobby too, I wonder what he would think of these experiments :)
Thanks a lot mate, I love that engine too! Sounds lovely too - I wonder what he would have thought!
Thanks for watching - Sam :)
You should make an express running session with Little Miles,the SR 0-6-0 and the ‘’ trackcopter ‘’.That was a great experiment.Keep up the SUPERgreat job!!!-The LMB Channel
I certainly could do that - great idea!! :D
Thanks for watching - Sam :)
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.
Ahh very interesting! And banked curves would be awesome too! :D
Thanks for watching - Sam :)
Me and my Dad did back in the 95. Took model rocket engines and strap them to a G scale car and cut out back of a LGB Stainz engine. Took it to the convention in St Louis and had the fastest Drag train at the drag race that year.
haha that sounds incredible - I'd love to try that in 00 gauge - a job for outdoors though ;)
Thanks for watching - Sam :)
I think the little 040 could be modified using a performance motor they sell for slot cars. I know hornby's sister company scalextric used to make performance tuning motors to replace the standard motors in the cars. The 040 motor is the same as some found in the scalextric cars.
Yeah you could do that for sure - though I think a geared system would struggle to go faster than those propellers! ;D
Thanks for watching - Sam :)
(loco one) "hey you've got to come back with me"
(loco two) "were?"
(loco one) "back to the future!"
haha! Great Scott!!
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
haha that must have been crazy - an awesome idea!! :D
Thanks for watching - Sam :)
OMG! Sam. Given that train so much speed with big sparks from track and train I thought that thing was going to explode!
haha I thought it was going to explode too - pretty scary stuff!! ;D
Thanks for watching - Sam :)
I noticed that you got a cow on a flatbed rail car, on your shirt. That’s sick. I like it 10/10 in my book
haha thanks a lot Daniel - glad you liked the Bullman shirt, lol! ;D
Thanks for watching - Sam :)
Sam broken the speed of sound
haha yeah, only to scale though! ;D
Cool!!! So does this mean we can have models that look similar at 1:87 scale (HO) but we can also have models that can match the speed and performance of the real locomotive?. I'd love to get an HO Ouigo, TGV or AGV with the exact scaled speed.
haha that would be amazing actually - I wonder if you could hit like 60 with one of these?!
Thanks for watching, Sam :)
All that sparking and arcing was fun. c: The damage to the track and wheels came from that because the electrical arcs are hot enough to vaporize and ablate the metal, which causes little molten bits of metal to splatter on everything nearby.
haha glad you enjoyed it - yeah you're right, quite impressive power there! :D
Thanks for watching - Sam :)
upgraded rail chopper: hits 850 mph
Thomas in hero of the rails: ARE YOU CHALLENGING ME!
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!
Ahh awesome!! Any idea what speeds you saw?!
Thanks for watching - Sam :)
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.
Thanks a lot for the tips - I'll be sure to try that! :D
Happy New Year,
Sam :)
Wow Sam! What fun! Loved this video. Can I say though, I really think you should be careful welding with model railways using nice burny plastic on nice dry wood and nice burny carpet in the middle of your fantastic burny layout haha! Great video. So much fun to watch. Nice work mate
haha thanks very much Chris! No worries - I took the proper precautions - and the raised track meant that no hot sparks would get to the carpet ;D
Thanks for watching - Sam :)
Very true but heat plastic wood and carpet can all spontaneously combust as you know. Living life on the edge so early in the year Sam! What is going on !? 😂. Also. The new range of t shirts are pretty cool I must say. I recently bought the 121 dmu you reviewed also and I’m very very pleased with it. “Model junction bury st Edmunds” brilliant model shop for railways. Take care mate. Keep it up
god damn that last run turned it into an F1 loco XD
also those sparks were the time space continuum errupting as the loco almost hit the magic number to time jump XD doc brown would be proud!
haha I know!! Great Scott!! xD
Thanks for watching, Sam :)
