Minecart with Hopper

A Minecart with Hopper is a special type of minecart functioning in a similar fashion to a Hopper as it goes along its respective rail. It will collect items lying on tracks and from containers above them.

Behavior
A Minecart with Hopper will take in items which are lying nearby (range only slightly larger than the cart itself), or inside a container above the track.

Unlike an ordinary hopper, items are not automatically transferred from the cart to other containers, but it can be unloaded by a hopper directly underneath the track, just like a Minecart with Chest.

The hopper can be disabled or enabled by using an Activator Rail. When a Minecart with Hopper runs over a powered activator rail, it will stop taking in items; an unpowered activator rail will cause it to resume picking up items. This effect persists even after the cart is no longer on top of the activator rail.

A Redstone Comparator will only work with the Hopper and Chest Minecarts if you place the Minecarts onto a detector rail with a Redstone Comparator next to it.

A Minecart with hopper will travel more than 85 blocks without stopping (as opposed to a normal cart going less than 12 blocks) from a dead stop using a 2 powered track starter even with another cart in front of them. This makes them excellent for moving carts long distances when you have little gold.
