FAQ
How do I craft a powered rail?
Combine 6 gold ingots, 1 stick, and 1 redstone dust in a crafting table to produce 6 powered rails.
How do powered rails speed up minecarts?
When powered by redstone, a powered rail gives passing minecarts a boost in their direction of travel, increasing their speed each tick they cross it.
What happens if a powered rail is not powered?
An unpowered powered rail acts as a brake, rapidly slowing and typically stopping any minecart that travels over it within about one block.
How many powered rails do I need for a long minecart line?
A common rule of thumb is placing one powered rail roughly every 8 blocks or so along a straight track to keep a minecart moving at full speed, though the exact spacing depends on the track's layout and slopes.
