When detector rails were first introduced, I thought, "Cool!". But when they did not distinguish between empty carts and loaded carts, I thought: "What's the point"?
Can anyone explain what the point of the detector rails are as they've been implemented? Is it a glitch that they don't distinguish between loaded and empty carts? Stone pressure plates (you know, the ones used to make the detector rails...) distinguish between empty and loaded carts.
So what are the general thoughts on this? Should detector rails distinguish between loaded and unloaded carts or not? If not, then can someone explain to me what good they are?
Detector Rails are a type of rail that acts like a pressure plate, and the first rail switch.
When any kind of Minecart is on top of the Detector Rail, it will generate a redstone signal. The signal will be transmitted to blocks that are adjacent to the detector (including Powered Rail) and redstone placed under the rail, like pressure plates.
Detector rails can be used for many things. One train station-like feature could be activating a note block to indicate that a minecart is approaching.
Detector rails can be used with a memory cell to power powered rails for long tracks.
Additionally, they can be used to create a one-way gate to a Powered Rail, with any carts coming the other way slowing down if not stopping completely.
They also can be used to activate arrow shooters to create a minecart-friendly mob trap.
A trap based on the land mine trap can be built with powered rails as a stand in for a regular pressure plate, then placing it in a rail system to kill the occupants of minecarts. If water is beneath the TNT the explosion usually won't destroy the pressure detector rail and can't destroy the mine cart. Because the mine cart absorbs the blast, a detector rail trap won't usually be lethal to anyone outside the cart or a few blocks away. There is a chance that the minecart will bump the TNT and prevent it from falling straight down and not touch the water and therefore destroy blocks when it explodes. It is also possible for a very fast moving mine-cart to skip over the pit the TNT makes as it falls, thereby evading danger.
As a defense mechanism in multi player or for your own challenge, you can make a rectangle using powered rails, regular rails, and detector rail. you make a box around it with glass except the floor. at every detector rail have a red-stone rail leading to a dispenser filled with arrows. When you begin the movement of the mine carts they'll pass over the detector firing the arrows in a constant pattern until you run out of ammo. It is also good for speed killing by filling a hole with mobs and slaughtering the mobs inside. You can get a lot of resources this way.
