Can confirm for 1.21.3 |

Powering the rail in that manner goes against how redstone works in all other situations. Fixing this bug would lead to the creation of a "special case" scenario which may unnecessarily complicate redstone. On the other hand, intuitively the detector rail should power the powered rail that it is connected to, and so it is worth thinking about. A solution to this bug may be to allow sloped activated detector rails to not only power the block they are placed on top of (as they do currently), but also the block they lean against; essentially like two levers within the same block space. This is an intuitive solution and would also make sense within the context of redstone as a whole. It would also mean that the same detector rail would also power, for example, a redstone lamp placed on top of the block it is leaning on. |

You can use a workaround of using the detector rails to power some redstone and then use that to power the rails which is effectively what should be happening in the first place with the detector rail next to the powered rail. Dimitar is correct, it should act like a flat surface. After all, redstone works on a slope so why shouldn't a rail? |

... that would defy the entire point of detector rails though. |

I m afraid that I cannot agree with you. Rails should only share power with rails of the same type. In your example, detector rails != golden rails . So it should not.
Just as golden rails never share power with activator rail. |

For anyone that does not understand the bug (for whatever reason) please look at my attachment. |

"Don't you think that is how redstone works ?" No. It does not work that way. Look at it this way: There is an rail which should give redstone power to the upper rails. The detector rail should give redstone power to the upper rails, just like it does to surrounding rails on a flat surface.
Sounds the same, huh? |

I don't think that is a bug. fixing this will lead to adding a special case,which is not we want. (sorry for my pool English) |

confirmed in 18w05a, the exact same behavior occurs. |

As far as I can tell from testing, detector rails only power themselves, and the block below them – they will activate redstone-sensitive blocks next to them, but don't actually "power" the blocks around them. Dust placed next to them will be powered, but you can't draw a signal out of a block placed next to a detector rail using a repeater. So when the detector rail is above the powered rail, it powers the block next to the powered rail, which in turn activates the powered rail. The problem is that the concept of redstone signals isn't actually represented in the code anything like we perceive it to work, which makes the mechanics kind of inconsistent and causes a number of the outstanding redstone bugs. Signals are propagated mostly through block updates and checking the blocks around them, rather than blocks actually carrying power information. Powered rails don't actually follow the normal redstone rules for power propagation, and the way they carry power has some bugs of its own. A few of the developers have mentioned that they'd like to give it a major overhaul to fix some of these bugs, and I believe this was considered a possible target for the next major release at one time. I don't know if that's still the case; I haven't heard any mention of it recently, and 1.9 has already been labeled "The Combat Update". They've always got a variety of things in the works, and focus on different aspects as time, interest, and inspiration allow. Considering all that, what would be a "pretty straight forward fix"? They can:
So is there a plan to fix this? Sort of. Not this issue specifically, and probably not soon. It would depend on how much negative impact any change would have, and whether it would outweigh fixing this particular case. I haven't made much use of detector rails, and am not familiar with the types of contraptions people have built with them, so I don't know what the impact would be. That would be a good discussion for players and the developers to have in order to find the right solution to the problem. |

Confirmed in 1.8.3. All I want to know is if there is a plan to fix this: yes or no and what potential time frame? Yes, there are workarounds, but seems like a pretty straight forward fix for the next version. |

I can confirm this in 14w20b, 14w18b and 1.7.9. Is this a case of a bug re-emerging, or has it been consistently broken for all this time? I have to admit it's fairly esoteric, as a redstone torch is much resource cheaper than a detector rail, but there are times I have wanted to use this due to space issues. It also means that up-slope activator rail mob unloaders don't work, and I have a use for that too (a one way mob unloader, for example). |

This bug is over a year old and still not fixed?!?!?! Anyway, affects level powered rails attached to sloped detector rail when powered rail is above detector rail. PUHLEEZE fix this? seriously complicates my auto sorter :/ 1.7.4 |

Is this still a concern in the current Minecraft version 1.6.4 / Launcher version 1.2.5 ? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases. |

Can confirm. |

Though obviously this is a redstone issue, i'd like to comment that powered rails provide power to each other when placed on a slope. To me, detector rails should also work to provide power to powered rails on a slope for consistency. |
