The Auto Miner is a machine that will dig for you. It can also place planks, rails, powered rails, and red-stone torches as it mines.

The miner will pick up items as it mines. It won't pick up anything that doesn't stack to 64.
It will use planks to bridge so that it doesn't fall. It can use any kind of planks, including planks from other add-ons.
If it has rails, it will place them as it goes.
If it has powered rails, it will place one every 16 blocks.
If it has red-stone torches, it will place them next to the powered rails.
To power it, use Coal, Charcoal, Blaze Rods, or a Lava bucket.
It can also be powered with Ender Plasma and Nether Coal from my other add-on MineRe.
The drill breaks after 6000 blocks are broken. It can be repaired with another diamond drill or by using diamonds on the miner.
Durability and fuel are remembered when the miner is broken into item form.
The miner can be started and stopped by hitting it. It will start when given fuel.

This add-on also includes the Enchanted Minecart.

A Minecart upgraded with Amethyst that can go up to 10x the speed of a vanilla minecart.

It's recommended to add guardrails to your tracks so that it doesn't fly off.

It has to be placed on rails like vanilla minecarts.
