Ill make this short. People use WAY too many powered rails. You move the EXACT same speed with a powered rail every other block as you do with a powered rail every 32nd block. After looking around, the OPTIMAL ratio of powered to normal rails is 1 powered rail and then 37 normal rails. You will move 0.4% slower. That is unnoticeable.You can get away with these next few patterns as well, with more slowdown.1 rail every 42 meters: 6.4% slowdown1 rail every 48 meters: 16% slowdown1 rail every 60 meters: 28% slowdownIMPORTANT NOTE: 1 meter is 1 block.END THE MADNESS!!!! Stop overusing powered rails and torches.IMPORTANT EDIT- This WILL work with chest minecarts. They will go alone, with a reduction of a few extra percent, or with a player behind them at full. The player WILL NOT be pushed back by the chest minecart. However, when you reach the end of the track you could be, so a minecart unloader is recommended.ANOTHER IMPORTANT EDIT- This does work on all corners, EXCEPT forimmediate u-turns (the turning tracks are DIRECTLY next to eachother.) However, u-turns are fine if a block is between the turning tracks.
