Digging Molecart

The Digging Molecart is a Minecart variant that lays tracks down as it digs through the ground.

Usage
Once mounted on existing tracks, the Molecart moves forward at a slow rate, while digging out a tunnel five blocks high and laying track as it goes. The cart will only move and place tracks horizontally, and even putting started tracks in a diagonal configuration will result in the cart leveling out and digging horizontal immediately.
