Digging Molecart

The Digging Molecart is a Minecart variant that lays tracks down as it digs through the ground. It creats minecart tracks as you go further.

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.
