[Tutorial] Minecart Loaders & Unloaders 

🔴🔴1.16 works back after 6 years :)🔴🔴

I can confirm the 3rd design for an item loader still work in the 1.19 version of Java but I am not sure about the others as I haven't personally tested them. The tutorial is very useful and it was what I was looking for to fit into a design I am currently working on, by combining existing redstone designs into one. Thank you for the useful guide Rex

An important thing to note about these designs is that in all the unloader mechanisms, the chest below the hopper is absolutely necessary. When you have two hoppers instead, the items slide right through without activating the comparator, but a hopper and a chest seem to stall the item flow by just a tick, enough so that the comparator can detect that something is in the hopper and do its job.

Dude, I just gotta say, this video was the first time I dipped my toes into minecraft 5 years ago, and since then I've enjoyed countless hours designing an build redstone contraptions. I just came back to this video to refresh after the 1.14 update, and it's amazing to see that these designs are still functioning. Just wanted to thank ya for the quality content! Cheers

!.14.2 I confirm is working, thank you a lot.

1.17, still works to this day. I make my super smelters with this circuit, one for the fuel and another for the input. Easiest way to set up a smart super smelter ever.

I really dig that 3rd system. It's beautiful!

100 years ago I've built it in my windows 10 edition world and now I've built it in my 1.18.1 java world and it still works!

The most "complicated" one still works to this day, perfect use for my application, thanks!

I appreciate you explaining the function of each component, as opposed to just going "Ok, you put this here, and these go right around here, and throw down a comparator, and there ya go!"

update from 2023, still works in 1.19.3 there is probably a better way to do this by now but this worked for what i needed.

i couldnt remember the third design but i knew this is what i needed for my circuit. i wish this came up higher in the search results cause it took way too long for me to be able to find this

This video is literally 6 years old now, but if you see this comment, I just want to thank you for the last minecart loader design. I haven't seen it anywhere else but it does exactly what I want it to do for my furnace array and no other loaders have been able to cover all possibilities. Thanks man!

Love how you explained why and how everything works! Made learning so much easier and makes so much more sense!

You have no idea how long I've searched for this... TY for the explanations too it helps a lot. Works in 1.14. I do want to add though, that I have 1 sticky piston for the fence due to a Slime Shortage, so the circuitry is different for the logic.

that third design is ingenious bro

Works in 1.16.3 and it's amazing! love you so much haha

I'm just commenting because I'm genuinely so thankful for that final design. I'm playing in 1.19.0 bedrock edition and it was literally exactly what I specifically needed. Most designs were using Hopper minecarts but the thing is that I needed it for a gold farm and I wanted to smelt down the swords into nuggets. Accounting for the chest Minecart was super helpful. Also the fact that you created logic that sent the minecart if the minecart was full OR if the hopper was empty was also SUPER useful and I was trying to find a way to come up with a solution but I'm so thankful I found this tutorial. The lever into the side of the comparator in particular was especially helpful. Serious props, you're a legend dude.

Thank you the third design is exactly what I needed to build in my sheep farm to replenish the shears in the dispensers :)

I know it's a super old video but I keep forgetting the build and it's so helpful. you rock

I've developed a fix for an issue with the last loader. The issue was with mixed items the cart would never fill up and it would sit there blocked. The fix is for the "release when full" device and changing it to a "release when almost completely full" device. Replace the lever with a cake and put a comparator in front of it. A cake has power 14 rather than 15. The net effect on this device is the cart is released right before being full. Alternatively, one could filter their items and never get stuck items (which is what I've been doing before this idea). However, for my iron farm I'm going to reduce lag and cart only "almost" full carts of iron & poppies. I hope this tip helps!

Great Tutorial. Appreciate you explaining the circuit logic as well. Most Tutorials I watched are mererly "cooking recipes" which leave me being able to copy their design, but not understand and or/adapt what I am watching.

still works perfectly in 2019

This setup with most complex, and basic unloader works in 1.19.2bedrock! Supports my nether portal sword overflow perfectly!! Thank you for the steadfast design.

In the last design, change the block on top of the piston to a Redstone block and remove the comparator that is going out of the hopper if you only want full minecarts. If you want to get the minecarts instantly back in place you can put a dispenser at the back of the track with chest minecarts in it and hook it up to the torch that goes off if the minecart is full. (works for ps4 January 2017)

You are not only my favorite clone, but the only one who actually helped me from the 20+ tutorial, a weeks worth of thinking, and at least a 100 hours wasted.

it's been 9 years but it still work this is bloody awesome

This is imperfect. I made one more advanced. I needed the minecart to pick up items, switch rails when full, then stop and unload items until empty then it goes back to original track to pick up drops.

Thank you soo much for the detailed tutorials , and it still works in 1.18.1 (Java) !! I was worried about how to transport my cobblestones from the farm to the storage room, but it finally been solved after watching your video !

I really appreciate your explanations not only what to build but what all the pieces are for. I definitely need to follow you!

Thanks a lot, works well with my sheep farm. Shears overflow easily so thanks for this. Works in 1.17.1!

Great to see you posting again! I just needed this for a build!

Adapting this third design to evenly distribute items in a smelter array. I was looking for a build that combined a detector rail with a powered rail trigger. Perfect.

I'm happy to let you know that your (what I assume is yours) minecart unloader design is the best as far as I've seen. The newer designs are cool but one issue arises and that is the Minecart doesn't stop to unload and the signal repeats itself this sending the Minecart away after only unloading 3 blocks. Excellent work.

Thank you so much! After 8 years left and it works in 1.19.2

Great video. I like that in most of your videos you explain (at least partially) how the circuits actually work. Most video makers don't, and that makes it harder to learn how to modify designs or come up with new ones.

Little problem I ran in to with the unloader: I had a couple of hoppers in a row leading to my storage system and it didn't unpower the rail. It just extracted 1 item and left immediately. Easy to fix by putting a chest under the hopper that extracts from the minecart. Thanks for the tutorial, it's a fun build! (1.14.2)

Can confirm this still works on bedrock 1.14.60, if you’re like me any you build these as shown before placing them on you’re survival mode only thing I would suggest is, where the 3 activator rails are placed next to the detector rail, place only 1, as the Minecart travels too fast for the activator rail to be deactivated to unload so bear this in mind. Great build 👍🏻 as my minecart currently takes about 2 min trip from mine to main base this helps me out a lot can’t wait to put this into survival world I’m building with daughter

Thank you for actually explaining how all of this works instead of just showing how you build it

Slight modification for 1.16, if you don't want to wait forever for hopper speeds to fill the minecart, remove the hopper, and move the chest down 1 space. Hopper minecart pulls incredibly fast and sends if it's not full, or until the hopper minecart is full.

I like it because you explain what you are doing , not just building. Very nice. Still working in 1.15.2.

Cool how after 7 years this is still a useful video

You are a GENIUS! This is exactly what I needed to finish my auto-smelter. Thank you so much.

I am building a smelter system and now you have saved my life with the third design!!! I have seen this design before but never seen a tutorial

fantastic tutorial dude. The contraption is super handy and you explained why it all works wonderfully. Thank you!

Thanks Rex. I know this is a couple years old, however, as said before, GREAT explanation as well, you took it slow enough for ANYONE to comprehend. This is the second time I've used this system. Yes, it is the third set-up. It also does work on the console. At least the 360 console. I needed something like that because I'm mining out a mountain. LOL. Thanks again. TWO THUMBS UP!! Also, it does work better facing East and West rather than North or South.

Works in 1.19.4 if anyone was wondering. Great tutorial btw I love it

Man this video is super helpful. I've been using it for the last 6 years to remind myself. Thank you!

Thank you very much! I will try if it works in 1.4., I will tell you here -> Yeah, it does work in 1.4. When you use the third design, just make sure that the Minecraft is touching the detector rail. Thank you very much! I got so much trouble with minecarts earlier, that my sister laughed at me all the time!)

This video giving me 90s sitcom vibes. I like it.

1.16.1 still good 🔥

Was looking for a simple tutorial about unloaders (the one that I made by my own was crap!) and worked perfectly... Thanks for the clear and well explained tutorial!

My lord thank you so much. I spent an hour messing with clocks and latches, but this is elegant and explained well! Also still working in 1.19.2 nice.

The third loader still works in 1.13, you just have to put the lever for the >= comparator three blocks away instead of one because otherwise it won't leave. Other than that everything is the same, great design and thanks for explain *how* it works otherwise I wouldn't've figured out how to make it work!

This is amazing. I have been looking for a tutorial that shows this in quality for a long time. Thanks a lot. You have earned yourself a sub!

The last loader was exactly what I was looking for for my super smelter, thanks so much!

Just wanted to add that the last part of each one (the part that stops the cart and drops off the items) sometimes doesn’t work if the minecart is coming in too fast. if you are on a server or your world is glitchy you will need to get the minecart to come in REALLY slowly so the system has time to detect the items and stop the cart. I did it in 1.8.9 so hope it helps

still works in 1.15!, heres a list of items for the last one: 1 detector rail 2 powered rails 1 hopper 1 chest 4 comparators 2 sticky pistons 1 fencepost 2 redstone torches 2 redstone dust 1 lever i dont know the exact block amount but u should be fine if you take around 32 solid blocks (half a stack)

People should learn from you on how to make tutorials the way you explain (if/else, yes/no) is something thank you, still works 1.16

Still works perfectly for 1.20!

Love this. Soon as I watched it I went straight and built it on our server.

I feel like a fool. I was trying to set up a timer system. Didn’t realize hoppers that were transferring items would signal a comparator. Thank you for the tutorial.

I've just built this loader design on 1.19.4. Thanks! I found a bug though, if your goods chest has more items than the minecart chest you might face an issue, if your minecart is not completely full and the hopper still has items it won't leave the station. To fix this, I replaced the last lever with a dropper and the dropper should be 80% filled so the signal coming out of the comparator is not 15. This way the minecart will leave with around 80% of it's cargo.

That's a beautiful third build. I've been trying to come up with something like that for a while, and now I don't need to.

I realize this video is old, but it now works on platforms. At least its working for me on Xbox 360. Thanks for the tut!

what is good about the first one is in multi player you can stack food and tools to restock the miner keeping the cart full so it will not leave till those items are removed then it goes back with the raw resources besides new rail always needs to be built as you dig deeper and further so keeping it simple is key a full chest will always fill one full chest you will never go over that amount unless you forgot to take stuff out that your buddy sent you item detector rail switch can auto a dump/fill send dump/fill send so the first setup would still work more efficiently these should be nether rails as well I think it's 1 block traveled in nether is 10 in over world this saves you time and materials in railing 5 minuets travel in the nether is 50 mins in over world so it's definitely worth it

I think I might snag some of the mechanics in this (specifically out of the last one) for my super smelter system. Basically going to be allowing a minecart to leave once it has signal strength 3 (46 blocks), run down a 23 furnace track and back, and then fill it back up to 46 by comparing the blocks as shown in the last build. Issue with checking the chest is it'd be hooked up to an infinite cobblestone generator, which will overflow the chest and not actually diminish as it goes down.

important note for the unloader, you can not have a hopper sucking items out of the hopper that is supposed to give a signal to the comparator. it will not work because the items move out too fast.

These sruff will work great in airports!

Still works! Linked the 3rd design onto my automated bamboo farm so it’s super helpful thx!

10 Years old and still working flawlessly

Still working in 1.13

1.17.1 and this still works, thanks so much for the tutorial.

Concise, well put together. Good job and thanks man. 💪

Amazing! Thank you very much! I was searching for something like this for so long, I've spent so many hours trying this but I couldnt get to a solution!

Thank you, been looking for something like that third design for a while

Here in 2021 this video still helps can confirm that the 3rd build still works also on bedrock going to try Java next

Bit of at derpy processing error at 8:17. Didn't notice that before.

The first two are no longer at a massive disadvantage due to shulker boxes you can now hook them up to a shulker box loader so they'd transport full shulker boxes in one slot which is equivalent to a single chest so that allows bulk movement using the first two designs

Thanks a lot Full cart condition worked for me in 1.20.1 I only needed that one so I just used 1 comparator to compare the cart with the torch

this was really helpful man. thanks. I made a self mining transportation but there were some flaws in it. this is a different version of mine in a way but same concept and it's better I think. good build man

thanks i made a little system for my mine with this, linked it up to a sorting system at the top.

Sidenote following bedrock 1.19 : do not attempt to use too many power rails in the event the minecart is traveling back to the docking station. in rare cases , the cart will travel too quickly and when it docks , the detector rail cannot sense and measure the cart's storage

This helped me so much! I ended up using the third design for my super smelter/ auto xp cacti farm build! :)

Great Design NanoRex! I just built a short test version of the advanced system in 1.11 creative. Worked perfectly. Now to build it on Bearcrafter.com (multiplayer survival) to connect my 54-stalk, BUD-activated cane farm to a nearby villager trading center. The farm produces 10 stacks of cane an hour, afk. That equates to about 20 ems an hour. It will be great not having to empty my inventory constantly to transport paper.

Could not like this more. Thank you!

Still working on 1.17.30 but you need to replace the redstone dust beside the the lever with repeater. If u dont replace that, the piston will retract and the minecart will go even it's not full.

Really smart, thanks. Still a perfect design and hard to find

1.20.4 works like a charm. Man i miss ur videos...

The minecart only leaves when it's totally full (full stacks), but it does get stuck if it's full with half stacks. Is there a way around this? That it also leaves when the 27 slots are full with half stacks? (using design 3)

Really nice video! I’ll be building this soon in my survival world. I have a massive farm on ground level and my base is on a mountain so this will make transporting seeds and crops much easier and use no inventory space

PLEASE use all of your inventions and things to make us a super adventure/puzzle map!!!

Still works in 1.16.1! Thank you!

this was awesome but so complex to listen to... i still dont get how the game understands the info your trying to get it to understand but this video has def giving me a new consideration for my auto farm to send the items to my tree house... so thnx

Still working after 9 years 1.20.4, thank you very much😀

Also for anyone wondering just made this in version 1.21 it still works after 10 years

The one at the far end still works thanks.

I see one flaw in the third design:If there are different item types being delivered into the minecart, sometimes one or more slots will be partially filled, but not fully. This will not trigger the mechanism to determine if the minecart is full.

old but gold

Hey Rex, Thanks for this. It's awesome and seems to be working in 1.11.2, albeit with a little strange behaviour somtimes (referring to the 3rd design here). E.g. When the minecart AND hopper are both empty, the minecart stays put - I am guessing this is intentional. If you have the spare time, would you mind performing a review of this design in 1.11.2 yourself? See if everything is working properly. I would be so grateful because this is basically the best minecart loader/unloader system I've seen anywhere! If not, thanks anyway - it's a great design. EDIT: I just saw you have a new design out! I will go check that out now :)
