I’m building a dual railway where part of it is sloped, and after getting powered rails 4 steps up realized that only the middle two were being powered from the redstone torch below; the rail segments at either end remained unpowered. I tried moving the redstone torch adjacent to the bottommost or topmost rail and when I do so those segments get power but not the other three. The odd thing is that I had pre-designed the entire system in a creative test world and the whole length of track up the slope (7 powered rails) runs just fine on a single redstone torch placed underneath the third rail from the bottom. I don’t see any reason why this won’t work in my survival world.

By the way I checked for similar open bugs and while this sounds similar to MC-99594, it’s different in that the earlier case has a broken slope while in this case the rails form an unbroken slope.
