Minecraft wiki entry for Train_station, associated text: A new idea is a machine reading your ticket. Have a hole, then a water shaft. 2 blocks in, put hopper and a dropper below that. And put some space further on. Put a redstone comparator next to the hopper above the dropper. Then, put 64x9 of your "money" in the dropper. Put 22 "coins" in the hopper. Then, put two redstone next to it and a redstone repeater after that. Wire this up to an AND gate and a redstone clock. Wire this up to the dropper and another wire to a dropper, which has all your tickets in.
