A Sticky Piston can duplicate powered rails, by placing 2 pistons 1 block apart running from a 2 repeater clock then place a hole 2 blocks from the piston so like the piston is in a spot count 2 blocks from the front then place a hole on the second block you counted then place 2 powered rails away from the sticky piston and power the sticky pistons from the 2 repeater clock then place a powered rail when it isn't extended it will give you two instead of one. And duplicate the powered rails from the front of the hole.
