When Minecarts are next to each other on rails and not moving they make the nois of moving!

*The minecrts would not make any noise.

*The minecarts made noise.

1) Place powered rails next to each other to form a track at least 2 meters long.

2) Place a block at either end of the track so that mine carts cannot come off.

3)Place mine carts on the track- more than the number of rails and it will make the noise of mine carts moving when they are completely still, especially when using unpowered rails powered rails.
