haha very well spotted - absolutely right - I thought that would be a fun touch! Interesting to see a model designed for resin printed with FDM too, and it worked better than I thought! Thanks for watching, Sam :)
Hmm…a true rack engine would be worth a try. Roco had a Swiss Federal prototype rack diesel or 3Kv. DC 3 phase overhead rack engine that might be out there.
14:00 It looks like the loco tripped over its own ratchet after the pinion wheel lost traction on the sleepers. That effect will be a direct geometric function of the climb angle. You are, in effect, re-inventing a rack railway system - just using an expedient form of rack. The failures you encounter are very similar to those that plagued early rack-railway systems, including the infamous derailment on the Snowdon Mountain Railway on its opening day. It is for this reason that SMR had to add an extra feature to the rack on the steeper sections (which constitute the bulk of the line's length) and a corresponding device on each loco and carriage, which physically holds the pinion into the rack. This extra piece of the rack is omitted on the less-steep sections since it is incompatible with pointwork. You could probably improve the Paddle Steamer's climbing performance by rebuilding the pinion with "hooked" teeth, like a water-wheel, and by constraining the movement of the ratchets so that they don't tend to lift the loco further off the track when under severe pressure. The latter is probably more of a safety feature than a performance feature. You should try to have both ratchets in place, as the forward one will be important for stability when engaged.
Redo your ratchet so that the notches have a backward slope, so they meet the sleepers at 90 degrees. That should help with the bumping out of the track.
This is a very cool thing to see. While the overall design is rather gimmicky (apologies), I am just in love with the concept of rack-and-pinion in model form. Love to see you tackle an engine from the Snowdon Mountain Railway with this design concept lol!
I made one of the snowdon railway (perhaps a more realistic rather than paddle steamer design) but worth a look: ua-cam.com/video/x5MWkqxSSzA/v-deo.htmlsi=b5yB8W5iQC67NAfO
There have been some functional rack and pinion locos made that can handle high gradients in model form. The brand Halling / Ferro Train has some quite adorable ones from various Alpine narrow gauge railways. Some even have their entire boilers and fireboxes mounted at an angle, so that they're level when climbing up hills.
I think the problem with both Speedy Pete and the Paddle Steamer failing the incline is that they were designed more for horizontal track than an incline and the problems they would have on inclined track. It seems that the problems with the paddle steamer were weight distrubution and losing contact with the track. If you look at photos of the engines on the Snowdon Mountain Railway and the Pikes Peak Cog Railway, they were built to look tilted forward so when they go uphill, their boilers sit flat. If you designed an engine like the Paddle Steamer with a sloped shape, sloped weights, and some sort of clip to keep the wheels on the rails, you could in theory build an engine that could climb a 45° angle.
Yeah that's absolutely true I think - they rely on gravity pulling them downwards perpendicular to the track to work... beyond 45 degrees the direction of gravity becomes backwards and down, rather than just down onto the track! Thanks for watching, Sam :)
Speedy Pete as I recall had multiple points of contact with track, Paddle wheel has only one at any given time, so the improvement is the motor can coast [no load] to full speed while ratchet is engaged. Therefore the paddle wheel with NO power will still be stalemate unless other loco can pull paddle wheel unit over the ratchet point - and as this is in effect a becomes a lever working in favour of the paddle unit Still fun video [as always] , totally enjoyed and admire the thinking that went it design and build. A challenger - dual inline paddle wheels, offset central gear drive by 1/2 tooth means always a tooth in contact with sleeper,... just a thought. TTFN
Great design. I must say that putting the two rachets give an unfair advantage over the regular locos as they have nothing to hold onto and the wheels will obviously slip. The competition should be between the paddle and the regular wheels. Even then, unless you have an engine that can pull the peddle steamer over and topple it, it will fail the test because you have now a very much larger motor in the P.Steamer. Now, that is a better name for it!
This is so cool, I love your experiment videos! Can the paddle steamer handle points and curves? Also, can you tell us what show Speedy Pete was featured in on TV?
Few edits I think are needed to improve the design. 1: add weights to the base of the frame with the wheels, this will eliminate the issue of the wheels coming up and loosing connection with the rails. 2: Give the teeth of the paddle a very slight reverse angle rather than the teeth coming straight out like they are now, this will mean that the face of the teeth will be flat on to the sleepers rather than ever so slightly ramped which is causing the skipping we see. 3: remove the ratchet pegs on the base that locks it to the sleepers upon reversing, this not only lifts the whole engine off the tracks, but offers a huge cheat in that is can only ever win by not allowing for lose. If it can't go forward then at least it will never go backwards, massively unfair. 4: make the paddle wheel much smaller or figure out a way to mount the motor in a more traditional way to keep the weight of the engine centered. It would be awesome if the motor turned a gear that then powered with a piston connecting rod to the driver wheel/wheels, as adding a second wheel might fix the issue of the odd gaps in the sleepers as well.
Seeing the Paddle Steamer in action, something I've really wanted to make since getting into 3D printing is a cog railway engine (namely the ones from the Mt. Washington or Pikes Peak Cog Railways). Yeah, it'd be best if the layout for it had a system to automatically stop it and change direction (which is not impossible), but it'd still be neat to have a running model of one of those goofy-looking engines that actually climbs a rack rail.
The ratchet is kinda unfair.. By design, no other engine can hope to pull the paddle steamer backwards and win cause it just keeps jamming into the sleepers. Think it defeats the purpose of a "Tug of War" Still though, the concept is really fun! Maybe you should try making an actual Rack and Pinion 00/HO loco with accompanying track to see if the technology works in miniature!
I've been doing some personal engineering projects for the past year or so about weird steam locomotive concepts and prototypes, and I want you to know I'm furiously jotting this idea down for a Marsh rack railway design. A larger gear probably wouldn't make mechanical sense, but a 7 1/4 inch prototype would be interesting
Imagine being the driver of the Paddle Steamer Locomotive on that 45 degree incline. You would think you could do it, but immediately, you plunge to your Death.
@@SamsTrains Y'know what? I've an idea - since this one's pure power, how about another speedster? A propeler, two propelers, a jet engine, a'la Thomas And The Jet engine or whatever can get the fastest speeds?
Your creation of the paddle steamer was amazing Sam. That was a fantastic experiment which you have done. By the way are planning to review the new Hornby BR 2mt Mogul at any point of time Sam?
I think it would be possible to solve the skipping issue almost entirely by having one or two less teeth on the main wheel. If you watch closely, when one tooth is engaged and holding weight against the sleeper with either coaches or a steeper gradient, the next tooth is coming down on the top edge of the next sleeper rather than coming down in the gap to properly engage with it. I have a feeling this is due to the fact that when a tooth beds in for traction it means the back tooth is at an angle, so thanks to weird trigonometry related shenanigans the actual distance between the edges of the teeth ends up not being long enough. Speedy Pete didn't have this issue since the chain drive essentially meant it was always engaging with the track "flat", so the teeth on the chain were always able to bite. When it's running on flat track without any load, the wheel can actually pull itself along with friction on the carpet combined with a little bit of momentum, so it doesn't skip. If the distance between teeth was larger, then when it's bedded in the next tooth will actually land in the gap rather than on top of the sleeper. Another quick improvement would be to add a stop to the ratchet to prevent it from going round and under the loco. When it started to lift, the ratchet essentially went back underneath the loco which effectively disengaged it entirely. Adding a stop just shy of directly down would mean the whole loco would have to pivot around the ratchet, rather than it essentially terminally slipping at about 45 degrees.
I love these kinds of videos from you, Sam. Nice work! However, I think the bit that keeps the paddle steamer from going backwards was a bit of a cheat vs. engines that didn't have the same part. Just my opinion.
Very amusing and very silly video Sam! Lol. Almost as funny as the video you made a few years back, getting a loco to pull the skin off a rice pudding! Remember that? How could one forget! Best, Pete.
I have found an unfair advantage for the paddle steamer! The ratchets, that are designed to stop it being pulled back mean that it can’t be pulled back by a normal model. And therefore, it is bound to win every time, unless of course there is enough tension to make the rope snap, of which is unlikely!
I am really impress with your design... apart from the gear teeth profile which looks as if its causing issues. However i cant think of a simple solution off of the top of my head other thsn make the "paddles" feathered as on a paddle steamer but that would introduce unnecessary complication. Changing the gear profile to an involute or cycloidal may help a bit but then again it could make matters worse so all in sll you probably have reached optimization. Having seen your machine i think that the only improvement would be to use a ratchet drive rather than a wheel. A crank driving ratchets wouldn't look anywhere near as cool. Well done. Excellent machine.
If you ran the Paddle loco on track that isn't "ON" any sort of roadbed, then those gear/teeth could get a deeper bite. Just the rails and ties/sleepers. Try it that way. John
How about doing the same thing except with a longer chassis and 2 paddles? It might be better or worse I’m not sure if it’s even possible. also maybe you could use 2 motors on the original to make it stronger. Another thing is maybe make the notches on the paddle a little longer and another thing is the back ratchet might be making it fail you could remove it and keep the front one. just some ideas I had!
Maybe a worm gear drive on the sleepers would allow more contact and smoother operation. Or angle the paddles to the rear by a few degrees to hook in better.
This was a neat idea! Now that you have a resin printer, you should re-design the GER 552, Gladstone, Old Copanog (etc.) to be resin printed! Edit: Ummm… we’re you able to heal bullman from his injuries???
ROFL! The other day I was wondering if mad experiments would continue appearing, and there we are hahah. Cracking crazy and I would not recommend sipping your thee or coffee whilst watching, lol. Sam, I think this one should be patented and to be build full size 🤣🤣🤣 I suppose 45 degrees is the tipping point in physics for doing inclines. Just make sure the prototype comes with a disclaimer 🤣🤣🤣
i already see so many ways to improve it. the constant skipping tells me that your cog doesnt have the adequate spacing for the ties and just pulls the train up rather than forward, making it skip till the tooth can engage the rearward tie to give a slight nudge forward.
I was waiting for your review and the number of coaches it could pull on straight and level track... Next up, a representation of Pearson's 8ft single 4-2-4T for the Bristol and Exeter Railway, with two 'paddle wheels' engaging the outer ends of the sleepers.
Pilatus Kulm The steepest cogwheel railway in the world, with a gradient of 48% and a length of 4'618 metres, links Alpnachstad with Pilatus Kulm at an altitude of 2'132 m.... Be interesting to see a version of that made.
The question is now, how does the "paddel steamer" couple if the hand of god is not available? :) Maybe it needs a bit of weight directly on the wheels rather than on the upper part of the chasis? Loved this video. It was fun to watch. Thanks for the smiles.
I feel like if you want to conquer the mighty 45 you'll need to take a page out of real world railways and 3D print a funicular car. Fun video nonetheless!
Maybe you could make a loco that is a combination of Speedy Pete and the paddle wheeler all in one and with the combination of the two combined into one loco it might be able to climb up a 45 degree angle
Yeah ! The return of the nutty experiments ! This one is both creative and imaginative, and the engine you made is fun to see. Thanks for the crazy job done here ! Uh oh, I've seen you bought a Rivarossi model. A surprise test for us in sight ?
I've seen something similar before. Not sure if the Nazis or the Soviets but one of them had a device to rip up the center of the track by destroying the sleepers !
The paddle is great for tug of war and flat ground but it’ll always fail at those higher gradients is what I’m seeing, to retro fit it for hills you’ll need to scrap the suspension as it’s giving the wheel to much leeway to slip, you’d also need some weight above the paddle to press it down onto the rails. And perhaps using axels to fit the ratchets rather than clips could call for less breaking off.
Add a long ratchet in the middle for hill climbing. Like triple the length, basically as long as you can get away with while still getting a good angle on the sleeper. It should be able to drop in at much less of an angle, I think... 😅
I think the padle steamer needs a new bigger gear and no kick back stoppers I consider that a lil bit of cheating sence the other engine no matter the power ain't gonna move someone stuck on the tracks
I like this, I don't like the locking ratchet though, it's kind of cheating? The mighty Deltic looked like it might have had a chance if it wasn't for that device. Is your track magnetic? Would some little magnets close to the track be a better solution than wheel weights? My mate used to be a train driver out of Waverly and he hated the job, he always talked about his dream of becoming the worlds first stunt train driver, jumping buses like Evel Knievel in his DMU lol. Can trains jump? Have you ever tried? Paul
if you make your front ratchet shorter, you'll find it does the incline better as it allows for the approach angle and helps keep the front axle grounded, you could also try thickening the paddles to reduce the amount of give (tolerence) between the paddles and the sleepers... hmmm.... challenge, accepted.... design mode on I guess...
That was what I intended... I did try to calculate it so they were offset, but I obviously got it wrong and had them synchronise perfectly! Thanks for watching, Sam :)
What if you lengthen the body, get rid of the paddle, and replace it with a screw running perpendicular with the track and using the track as a long gear, the track connection wouldnt be an issue and theres much more contactsurface...?
And it LOOKS just as threatening as it SOUNDS For real though, amazing video Sam! I love the attention to detail and actual engineering you put into these experiments! Your sense of humor's aging like wine too, I adored this one!
In all fairness, because the paddle steam has the ratchets and the rest of the locomotives don't Its an unfair advantage which could be considered cheating
I wonder if there's scope for a competition? Sam's loco v selected competitors over 3 or 4 tests at some convenient location. The great Egg Race, Scrapheap Challenge and Robot Wars used to be a really good way to play with engineering and even provide some inspiration for youngsters to enter the profession. This could be a You Tube based equivalent?
Question: could you do a part 2 video to this and this time when you do the tug of war can you do it with out the lock device that stop it going backwards in place,would like too see what the out come would be and using the same locomotives
hi sam. a good experiment except you cheated a bit with those back ratchet bars not a fair test lol i think you needed the paddle to be heavier to keep it from lifting
Your paddle wheel reminds me of the driving wheels of the Salamanca, a 2-2-2 with 2 cylinders, built in 1812 by Mattew Murray (1765-1826) the first ever steam locomotive to really do the job, even if on rack rails apt to fit its paddle transmission system.
How 'bout a speed contest with a Lionel flat car equipped with a "D" model rocket engine on 100 feet of Lionel straight track? I did that as a teenager.
Ah yes there is the tug of war we all wanted! (apparently * wild Bowman appears and moos* ) Excellent dessign on the new locomotive engine, overengineer by all means! i am fan of Voisin Laboratoire, Bristol Brabazon, Yamato... Tupolev ANT-20 (inspie of its name it was no ant, pretty big for its time plane). Ravel in engineering long enough and you get to make your marble machine or useless box. its fun and i appretiate the maddness of it all. Ah yes its raining trains hallelujah. 45° is quite steep conssidering real life railway tends to not do well anywhere near much less above 20 (without special track for some form of added traction). apparently light railways (trams) can go up to 14° in Lisbon but thats rather unique, most seem to not even reach 10°)

I think the same tests need to happen WITHOUT the ratchet just for fairness 😊
Completely agree
But it wasn't made to be fair, it was literally designed to win the Tug of War, no matter what
@dakshanbalaramesh it most certainly was yes, but would still like to see the comparison
Yeah I think that would be fun - I might give it a try!!

@@SamsTrains The 37 was giving it a very good go!

Hmm…a true rack engine would be worth a try. Roco had a Swiss Federal prototype rack diesel or 3Kv. DC 3 phase overhead rack engine that might be out there.
14:00 It looks like the loco tripped over its own ratchet after the pinion wheel lost traction on the sleepers. That effect will be a direct geometric function of the climb angle.
You are, in effect, re-inventing a rack railway system - just using an expedient form of rack. The failures you encounter are very similar to those that plagued early rack-railway systems, including the infamous derailment on the Snowdon Mountain Railway on its opening day. It is for this reason that SMR had to add an extra feature to the rack on the steeper sections (which constitute the bulk of the line's length) and a corresponding device on each loco and carriage, which physically holds the pinion into the rack. This extra piece of the rack is omitted on the less-steep sections since it is incompatible with pointwork.
You could probably improve the Paddle Steamer's climbing performance by rebuilding the pinion with "hooked" teeth, like a water-wheel, and by constraining the movement of the ratchets so that they don't tend to lift the loco further off the track when under severe pressure. The latter is probably more of a safety feature than a performance feature. You should try to have both ratchets in place, as the forward one will be important for stability when engaged.
Redo your ratchet so that the notches have a backward slope, so they meet the sleepers at 90 degrees. That should help with the bumping out of the track.

The concept behind this is really clever, you've essentially developed a way to make a functional rack railway from standard model track.
The next iteration should grab the sleepers by the outside like the pilatus railway (Locher Rack System).
I've been doing some personal engineering projects for the past year or so about weird steam locomotive concepts and prototypes, and I want you to know I'm furiously jotting this idea down for a Marsh rack railway design.

I wish you tested it against multiple locos! Would have loved to have seen what the results would have been
One of the few wheeled vehicles which can go up a 45° is the Unimog so a model loco almost going up that slope is really impressive
That's genius! I wonder if a pair of extendable arms with "hands" would work? Very entertaining!

the issue on the incline is that the center of gravity is too high. and if you give enough weight to hold the top bit down it's unbeatable
Pilatus Kulm
The steepest cogwheel railway in the world, with a gradient of 48% and a length of 4'618 metres, links Alpnachstad with Pilatus Kulm at an altitude of 2'132 m....
Be interesting to see a version of that made.
The question is now, how does the "paddel steamer" couple if the hand of god is not available?
:) Maybe it needs a bit of weight directly on the wheels rather than on the upper part of the chasis?
Loved this video. It was fun to watch. Thanks for the smiles.
You actualy made it i was asking for this for like a year🥳
I feel like if you want to conquer the mighty 45 you'll need to take a page out of real world railways and 3D print a funicular car. Fun video nonetheless!
Maybe you could make a loco that is a combination of Speedy Pete and the paddle wheeler all in one and with the combination of the two combined into one loco it might be able to climb up a 45 degree angle
Yeah ! The return of the nutty experiments ! This one is both creative and imaginative, and the engine you made is fun to see. Thanks for the crazy job done here !
Uh oh, I've seen you bought a Rivarossi model. A surprise test for us in sight ?
I've seen something similar before.
Not sure if the Nazis or the Soviets but one of them had a device to rip up the center of the track by destroying the sleepers !
You always impress with wacky experiments sam!! Great video
haha thanks very much Jack! :D
Thanks for watching, Sam :)
The paddle is great for tug of war and flat ground but it’ll always fail at those higher gradients is what I’m seeing, to retro fit it for hills you’ll need to scrap the suspension as it’s giving the wheel to much leeway to slip, you’d also need some weight above the paddle to press it down onto the rails. And perhaps using axels to fit the ratchets rather than clips could call for less breaking off.
Add a long ratchet in the middle for hill climbing. Like triple the length, basically as long as you can get away with while still getting a good angle on the sleeper. It should be able to drop in at much less of an angle, I think... 😅
I think the padle steamer needs a new bigger gear and no kick back stoppers I consider that a lil bit of cheating sence the other engine no matter the power ain't gonna move someone stuck on the tracks
I like this, I don't like the locking ratchet though, it's kind of cheating? The mighty Deltic looked like it might have had a chance if it wasn't for that device. Is your track magnetic? Would some little magnets close to the track be a better solution than wheel weights?
My mate used to be a train driver out of Waverly and he hated the job, he always talked about his dream of becoming the worlds first stunt train driver, jumping buses like Evel Knievel in his DMU lol. Can trains jump? Have you ever tried?

if you make your front ratchet shorter, you'll find it does the incline better as it allows for the approach angle and helps keep the front axle grounded, you could also try thickening the paddles to reduce the amount of give (tolerence) between the paddles and the sleepers... hmmm.... challenge, accepted.... design mode on I guess...
Can you and Chloe have a Tug of War? I'd love to see that. I wager Chloe might win, lol.
Nahh, I'd win easily ;D
Thanks for watching, Sam :)
One improvement that could be made is having the ratchets offset so that one is always engaged when the other is lifted
That was what I intended... I did try to calculate it so they were offset, but I obviously got it wrong and had them synchronise perfectly!
Thanks for watching, Sam :)
What if you lengthen the body, get rid of the paddle, and replace it with a screw running perpendicular with the track and using the track as a long gear, the track connection wouldnt be an issue and theres much more contactsurface...?
Could you make a improved version of the paddle steamer (more wheels 4-2-6) (bigger paddle wheel) larger smokebox & funnel for extra weight)
I cannot think of a more viscerally threatening name than *_The Paddle Steamer_*
And it LOOKS just as threatening as it SOUNDS
For real though, amazing video Sam! I love the attention to detail and actual engineering you put into these experiments! Your sense of humor's aging like wine too, I adored this one!
In all fairness, because the paddle steam has the ratchets and the rest of the locomotives don't
Its an unfair advantage which could be considered cheating
1:41 That's the problem class smokebox Sam, lol
Cheers Jasper & Willow
hahaha it is!
I wonder if there's scope for a competition? Sam's loco v selected competitors over 3 or 4 tests at some convenient location. The great Egg Race, Scrapheap Challenge and Robot Wars used to be a really good way to play with engineering and even provide some inspiration for youngsters to enter the profession. This could be a You Tube based equivalent?
Question: could you do a part 2 video to this and this time when you do the tug of war can you do it with out the lock device that stop it going backwards in place,would like too see what the out come would be and using the same locomotives
Yeah that would be very interesting actually!
Thanks for watching, Sam :)
Honestly just needed to upload the first 30 seconds 😂😂 sweet video Sam
hahaha!!
hi sam. a good experiment except you cheated a bit with those back ratchet bars not a fair test lol i think you needed the paddle to be heavier to keep it from lifting
The gear isn't this enormous, but cog locomotives are very much a real thing that work kinda like this.
Your paddle wheel reminds me of the driving wheels of the Salamanca, a 2-2-2 with 2 cylinders, built in 1812 by Mattew Murray (1765-1826) the first ever steam locomotive to really do the job, even if on rack rails apt to fit its paddle transmission system.
EXCELLENT WORK WITH THIS OFFICIAL VIDEO DESPITE SOME ERRORS IN THE LOCOMOTIVE!
13:58 looks like it jumped then pivoted on the back ratchet as it moved back
14:38 yes same thing
Great idea and design on the paddle wheel!
Try all three engines vs the paddle steamer in a tug-of-war.
I like this one. 3D print another paddle gear with wider teeth and I think you could get a steeper incline
An interesting designed Loco Sam - a boat meets a Loco!!! 🤔😉🚂🚂🚂
How 'bout a speed contest with a Lionel flat car equipped with a "D" model rocket engine on 100 feet of Lionel straight track? I did that as a teenager.
Ah yes there is the tug of war we all wanted! (apparently * wild Bowman appears and moos* )
Excellent dessign on the new locomotive engine, overengineer by all means! i am fan of Voisin Laboratoire, Bristol Brabazon, Yamato... Tupolev ANT-20 (inspie of its name it was no ant, pretty big for its time plane).
Ravel in engineering long enough and you get to make your marble machine or useless box. its fun and i appretiate the maddness of it all.
Ah yes its raining trains hallelujah.
45° is quite steep conssidering real life railway tends to not do well anywhere near much less above 20 (without special track for some form of added traction). apparently light railways (trams) can go up to 14° in Lisbon but thats rather unique, most seem to not even reach 10°)
You are either quite mad or a genius Sam. I loved the video.
I wonder if angling the teeth would keep it from jumping as easily? With the tips slightly ahead of the base of the teeth, like a saw blade.
In all fairness I don't feel like normal engines would be a stalemate, a mini big boy with a good motor and some weight would be a beast.
One must imagine -Sisyphus- The Paddle Steamer happy.
I reckon a Kato EF510 would give it a serious go. Only beaten on tractive effort by a psycho 60s Fleischmann tank engine...
The bad thing about model trains is that they have a price barrier for entry, and being a kid I don't have the money to buy any.
Me tinks tha' yea' need to get a better motor
I was thrilled to see the monster schools come back out!
That said, I need to see the Paddle Steamer fight Speedy Pete.
Ahh excellent!! And that's a good idea... maybe it's worth fixing Pete up to try it??
Thanks for watching, Sam :)
If you ever wanna make a more powerful loco, Just use A ratchet from a old projector
That was fun to watch!!!
You should make a cog railway that would be so sick
Have you experimented with different shape “paddles”? I’m was wondering if a different shape might stop the skipping.
Angled blands on the wheel would help the slipping.
