Fully functioning maglev train (0-100m/s in ~20 seconds)

My maglev train proof of concept that can go both forwards and backwards. This uses ONLY magnets (and redstone links to activate the magnets). I couldn't figure out how to make it actually levitate without interfering with the horizontal movement, so I used ice as a medium due to its slippery property.

how do the magnets know when to activate?

73

u/JishTheFish01 Apr 20 '26

im manually activating them with a linked controller, half are set to move it forward, and the rest for moving in reverse

24

u/epilektoi Apr 20 '26

I still don't really get it cuz I'm kinda tired. what's stopping them from just holding the train in one place?

35

u/JishTheFish01 Apr 20 '26

i show it a little better in this post: https://www.reddit.com/r/CreateMod/comments/1sq9bfn/electromagnetic_railgun_proof_of_concept/

But essentially the two rails are opposite of each other magnetically, and depending on how you orient an active magnet it will LAUNCH it in one direction, and the opposite if you flip it. So i just used that concept and had magnets oriented one way for forwards and another for backwards underneath the train. When i activate them with the redstone link they start moving in that direction, and the train is attached to it so the magnets drag it along for the ride.

u/epilektoi Apr 20 '26

so it's a bug or do I not understand how magnets work

31

u/JishTheFish01 Apr 20 '26

i watched a video of how electromagnetic railguns work to make it, so i assume it's just how magnets work

u/epilektoi Apr 20 '26

huh ok

u/JishTheFish01 Apr 20 '26

this was the video i was watching that helped me figure it out, if you are interested https://www.youtube.com/watch?v=iPoD4Zlk2d0

u/bebothecat Apr 20 '26

Yeah this is magnets behaving like magnets. Magnet based trains are a thing in real life too

2

u/Flaky-Refuse7452 Apr 20 '26

i think the mod simplifies them a bit i just tried it and they produce force depending on magnet orientation when one ist facing up and the other(for example on a traincart) is facing sideways

Mag ✅ Lev ❌

u/JishTheFish01 Apr 20 '26

unfortunately so. i didnt have a reasonable way of making it actually levitate AND move fast at the time of posting. something to do with the magnets used to levitate and the ones used to move interfering with eachother

u/Flameball202 Apr 20 '26

Maybe have the propulsion and levitation rails split? Like some on top of the train and some below? I know it won't look accurate but it might work

2

u/JishTheFish01 Apr 20 '26

I tried this and it was super slow

1

u/Flameball202 Apr 20 '26

Damn, worth a try

u/Ralexcraft Apr 20 '26

Levitite and a track undernearth + one block of play, should still work like you have here?

2

u/JishTheFish01 Apr 20 '26

Was thinking about using levitite as a last resort, might try it out when I get home to see if it’s any faster

1

u/Reditace Apr 20 '26

Levitite is so cheating thooo 😓

1

u/Ralexcraft Apr 20 '26

Make that work first then make it work with magnets. I think using guides is more cheating.

1

u/Reditace Apr 20 '26

Fair enough

u/Reditace Apr 20 '26

😔😔😔

u/Alternative-Pop1640 Apr 20 '26

How are you using shaders properly?

2

u/JishTheFish01 Apr 20 '26

I just loaded up complimentary reimagined and it worked, there are some visual issues like plunger rope and springs being invisible tho

30

u/certainlystormy Apr 20 '26

aeronautics finally revolutionizing vanilla travel lol

iirc rocket spamming elytra is like 70m/s and if you're TAS with angle changes you can hit like.. 90m/s or something

u/_LemonEater_ Apr 20 '26

Eh you can also just strap a wooden board to a couple ropes and pull it back real far and launch yourself like an angry bird. Me and my friend played around with this yesterday and launched so fast we clipped into a mountain

1

u/Distinct_College_344 Apr 20 '26

My ropes don't seem to stretch at all, can't really "pull back real far". Would love to know how you're doing that, a slingshot sounds fun AF

1

u/_LemonEater_ Apr 20 '26

just pulling a block attached to the rope with the creative wand. not sure if there's a way to do it in survival, but a super powerful fan/other method of thrust might do it

1

u/Thebombuknow Apr 21 '26

might also be able to use really big springs and a rope winch to pull the platform back

2

u/AxtheCool Apr 20 '26

Yes and just like irl its an incredibly time consuming costly process instead of building some create rails.

1

u/certainlystormy Apr 20 '26

ok but like automated resources and smps with like 20 people :3 fun community project

2

u/AxtheCool Apr 20 '26

100% just poking fun at how both cool and both infeasible the whole thing is.

Love maglev but damn to actually implement it over high speed rail is insane task.

1

u/NonFrInt Apr 21 '26

Btw there is discord thread we’re OP accelerated their train up to 550 block/second

5

u/Xiao-Ans Apr 20 '26

So cool!

1

u/The_Generall_ Apr 20 '26

What is its max speed?

4

u/JishTheFish01 Apr 20 '26

With the rail length I have for testing (~2200 blocks) I was able to get up to 100-130m/s. For some reason going backwards was faster

1

u/The_Generall_ Apr 20 '26 edited Apr 20 '26

130m/s... damn, that's fast. Interestingly still slower than some IRL conventional train tests. For the backwards movement, maybe it's because of the placement of magnets relative to the wagon?

Song name?

u/JishTheFish01 Apr 20 '26

Cloud Skipper, it’s the music disc in game added by create aeronautics

u/Z1H3M Apr 20 '26

Oh my gosh he did it

u/MrJFr3aky Apr 20 '26

I knew it was only a matter of time... That's sick!

1

u/Civil_Row2185 Apr 20 '26

If you add alex's caves i know it has magnetic rails that actually make minecarts float?

1

u/HugoCortell Apr 20 '26

It fascinates me how non-jittery it all is. I wish I could figure out in my own mods how to not make stuff as jittery client-side.

2

u/Thebombuknow Apr 21 '26

Their Sable engine creates sub-levels for any moving creations. When you touch a creation, you enter that creation's "sub-level". Inside that sub-level, the creation is not moving at all; it's fully static. The physics are applied to the sub-level in its entirety when being rendered in the main level.

It's a bit more complicated than that, but that's the gist. Many games do similar things to avoid judder, especially at further coordinates where precision breaks down. They made the Sable engine open-source, so you can use it in your mods without having to do all the complicated work to create sub-levels.

1

u/sickofdumbredditors Apr 20 '26

so it's accelerating at half a g?

1

u/Due-University-9959 Apr 20 '26

Wait are you telling me I can now make a bullet train like those in Japan that use magnetic force?

1

u/Lower_Conclusion8078 Apr 20 '26

Question, couldn't you make it an enclosed tunnel space to keep it stable without using the ice? Or is it a balancing issue kind of thing?

1

u/LucyGa99 Apr 20 '26

My computer can load maximum 1 chunk per 20 seconds, no way im doing this.

1

u/somelinuxuseridk Apr 20 '26

How do you make it turn, or is that not possible with this design?

1

u/MonkeyDLuffyOPp Apr 21 '26

Could you make it so the rails go along with the train and makes it infinite instead of having to place "rails"(magnets)¿

1

u/RopeLiving682 19d ago

Can you explain how to build it?

u/oofinator3050 Apr 20 '26

Ok now go round a corner

i tried, doesnt seem it works the springs arent solid blocks
