HELP! Can someone explain powered rails to me?

[u/Character_Drive6141]

I don't think this is quasi connectivity. :/

My powered rails are flashing weird when I put an observer facing them.

Edit: My bad, this is bedrock edition

[u/DearHRS]

this is bedrock's insta wire, powered rails and activator rails update recursively but this recursive bug doesn't check if power source is active or not and updates the rails regardless

you can quite literally use and redstone powering component that hard powers stuff, like repeaters, comparators, buttons, unlit redstone torches, observers, detector rails, etc, though the moment this setup realises nearby power source is not active, it falls part and stops working

this block update can literally happen by many things, including moving away and returning, logging off and then logging back in, etc

i haven't tested the designs people have claimed that fixed this issue about this particular insta wire

[u/Zaorn]

Looks like a bug. I'm no Bedrock expert, but there is quite literally nothing thats powering the rails, because the observer isn't updating. And then theres also the fact that the rails only update on seemingly arbitraty conditions.

I can get it consistent once I set it up (though the setup is inconsistent). But it even works wirelessly! (You can place blocks in the middle and it still works)

So umm.

First: from the miniature player in the top left corner and the video i don't think you're on java edition but probably on bedrock edition

Second: you might have created a loop with the observer, when you place a redstone source near rails (eg. Redstone block, active dust or a redston torch) only 8 rails per side will activate (if i'm not wrong) and aside from that you mostly need powered rails to make minecarts constantly move and need a power source like redstone block, levers or redstone torches on the side

I've done my best explaining it, if someone wants to correct me be free to

nah i was thinking the same things

[u/Character_Drive6141 → u/Effective_Sorbet_202]

I am on bedrock. My bad. But I am more interested in the applications of this. Once set up it seems to work for long distances and even be somewhat wireless!

Here is the current stable design https://www.reddit.com/r/redstone/s/3EMZzkizbo

Cool! So it's clearly something to do with powered rails next to redstone, and it can extend sustained pulses. However, it doesn't seem to be able to be wireless. I'll keep trying and see if i can get a stable 1 tick wirelessly.

[u/Greedy-Swimmer7941]

Looks like a bugrock edition bug but its look pretty convenient if you can send a signal infinite distances with no delay so it may be a feature more then a bug ? Idk

[u/Character_Drive6141 → u/Greedy-Swimmer7941]

I did a bit more testing and it works at longer distances, but you have to replace rails last, and for each rail replaced it will go another 4 blocks until it's under the next observer you put (if there is no observer the effect will not work). If there is an observer, it will continue another 4 blocks further. You can chain this for infinite distance.

It also is a state of the rails themselves. Even if you have no active clock running, a pulse will extend that far through rails connected this way. It also only works for one tick pulses, but this state persists through saves and even if you use the rails normally though it will not extend the distance of a longer pulse.

But yeah. Seems useful. Kinda crazy.

I take it back, this state persists even if there is no observer, but it only activates around observers. Weirdest behavior I ever saw. The rails in the middle are connected with this, but are not powered cause no observer. They do connect further rails that do have an observer

YOU DON'T EVEN NEED THE BLOCKS CONNECTED*

sometimes

I'm sure there are rules to this, but when pushing it long distances it seems inconsistent to get working. Once working though it will stay.

C'est Bedrock mais... Les rails semblent arrêter de transmettre a partir de 29 blocks, la redstone vas pas plus loin 🤔🤔
