Detector Rail — Recipe & Uses

Crafting Recipe

3 iron down each side column + a stone pressure plate mid-center + redstone dust bottom-center = 6 detector rails.

How It Works

While any minecart sits on a detector rail, it emits a strength-15 signal (and weakly powers the block beneath); the signal cuts when the cart leaves. Think of it as an arrival sensor.

Practical Uses

Auto-open station doors, light platforms on arrival, restock via droppers, or feed a T-flip-flop to toggle powered rails. Superior to pressure plates: only minecarts trigger it — foot traffic can't false-fire the system.
