Digging Molecart

The Digging Molecart is a Minecart variant that automatically digs a tunnel and lays down Minecart Tracks. It is sold by the Zoologist for once the Bestiary is 60% completed.

Once mounted on existing tracks, the Digging Molecart moves forward with a maximum speed of, digging out a tunnel five tiles high and laying track as it goes. The cart will only move and place tracks horizontally, even if it is started on a diagonal slope.

Tips

 * The Digging Molecart is one of the most efficient ways to cut containment trenches through the world if the player wishes to maintain world purity. Vertical hellevators can be cut easily with bombs, but cutting horizontal paths is more difficult until the Rocket Launcher becomes available in Hardmode.  If the player does not wish to feel rushed in containing the spread of evil biomes during early Hardmode (an abrupt difficulty spike in the game where the player needs to work on other resources), the molecart can be used to create several subway trenches across the world before entering hardmode, which also allows for a large and rapid search area for early Hardmode ores and other resources.
 * The Digging Molecart can be very helpful when constructing underground arenas such as in the Underground Jungle. Starting a new track of rails four tiles down from the last track will clear out the old one as the Digging Molecart lays the new one.
 * Because the cart keeps all of its momentum, the player can leave the game running to make a very long track automatically. This can help immensely with moving around the world.
 * The Digging Molecart can be used to bypass the Creative Shock debuff.
 * It does not break the placed rails, however.
 * It can also break the Eternia Crystal Stand.

Trivia

 * The Digging Molecart strongly resembles the Mole Tank transformation from the Yoshi's Island series.
