I have been following a tutorial on youtube regarding building a minecart station. Now I have had no issues whatsoever until I hit the cart loading section

unlike in the video (19:19 onwards), everytime my Pistons extend or retract, the rail keeps popping and turning into a drop. Any ideas on how to fix this would be awesome, world save can be provided if it will help with the fix.

  • What point in the video are you referring to?

  • Sorry I linked the timecode but it didnt work, updated OP to show 19 minutes 19 seconds onwards Commented Nov 28, 2013 at 15:10
  • To push the rail you need to make sure both pistons fire at exactly the same time, if they're out of sync it'll pop off.

  • They both do fire at the exact same time, I have double checked it Commented Nov 28, 2013 at 15:13
  • in that case it might have broken again in a recent update. You'll have to retool it to pull the track away, and then the block underneath (in a different direction).

Unfortunately, it does seem that some update between 1.4.7 and now has broken this particular aspect of the design. But it's a rather simple fix if you want to continue with this particular Pez Dispenser design (referred in the video as a "cart hopper"). You just need to send the cart forward above the hole where your cart hopper is. The simplest way to do this is like this, with a powered rail pointed towards your cart hopper. You can extend this rail however you like (you can even connect it to the arrivals line, and have it sent back to the cart hopper when you get out of the cart using a pressure plate).

Simple fix

However, some of the recent updates have given redstoners some interesting options with Minecart dispensers; the old Pez Dispenser design is no longer necessary. One of my personal favorite designs these days that combines cart launcher and cart retriever is this one:

Hoppers and dispensers

When you push the button, the dispenser dispenses a cart, and launches it (be quick to catch it, or you can use a powered rail and a tripwire down the line to have it wait for you). When you come back, break the cart, and the hopper will pick it up and put it back in the dispenser. You can hook this bad boy up to whatever track switching mechanism you plan to use, and you're set.

  • Also, this same YouTuber did a shorter series on how he did his station in 1.5, with hoppers and cart dispensers.

  • Nice design. Is there any automated way to break the cart? Or do you have to do it manually?

  • @John You have to do it manually. You could probably get an arrivals-only section with a cactus, but I couldn't figure out a good way to incorporate a cart-breaking mechanism with a combined departures/arrivals section.

  • not 100% but the best answer by far so thank you Commented Jun 4, 2014 at 19:28

You need to put a block down in the place where the piston will be when full extended.

When the piston extends, it will PUSH the rail; you need to have a block where the rail can adhere when it is pushed. Its impossible to keep the rail in place if the block you put is a transparent block like a torch, leaves, glass pane, etc.

Please post screenshots for more specific advice.


As Vitor said, The rail can not be pushed over a transparent block or it will break. Transparent blocks include,(Leaves, glass, air, torches, glowstone, stairs, fences, ladders, fence gates, other rails, redstone... etc)
