Minecart with Furnace

Minecarts with Furnace (also called Powered Minecarts) are a special type of minecart that was implemented in the Seecret Friday Update 7. It accepts coal or charcoal as fuel for powered movement and can be used to push other minecarts, thus functioning as an engine.

Crafting
A Minecart with Furnace is crafted from a Furnace and a Minecart, as shown below:

Usage
To use the Minecart with Furnace, first place it on a track. Select your fuel (currently only Coal, Lava Bucket and Charcoal works) then right-click on the Minecart. When right-clicking on the Minecart, you want to face the direction you want it to travel. You can make the cart change direction by right-clicking it while facing the opposite direction of travel. Your coal will be lost once used on the furnace.

Behavior

 * Breaking a Minecart with Furnace gives a plain cart and the furnace back (but any fuel inside will be lost).
 * Minecarts with Furnace cannot push other carts around 180-degree hairpin turns.
 * A player in a cart adds significant weight, requiring more power to push.
 * 1/1 (and possibly 1/2) slopes are too steep for a single Minecart with Furnace to push a single occupied cart uphill. 1/3 slopes appear to be gradual enough for success.
 * Going up at a slope of 1/3 (two flat-rails between each up-ramp) will allow you to push your train upwards, as it appears the Minecarts with Furnace have force applied in intervals.
 * Multiple Minecarts with Furnace yield more pushing power; 2 powered minecarts can push a player-occupied minecart up a 1/1 slope. (although very slowly).
 * A single Minecart with Furnace can push an occupied minecart up a 1/1 slope if there are additional minecarts being pushed (possibly due to bumping physics).
 * When a powered minecart runs out of fuel, it does not break.
 * One piece of coal seems to power the minecart for 4 minutes. Distance varies based on ramps and other objects on the track.
 * If too much stress is put on the Minecart with Furnace then it will stop. Right-click activates it again.

Trivia

 * Minecart with Chests and Minecart with Furnaces are the first crafted items created from two separate crafted items.
 * Right clicking will cause the Minecart to go forward a little bit, even if it is not loaded with fuel.

Bugs

 * As of Beta 1.8.1, Powered Minecarts cannot push minecarts on north-south facing track.
 * As of Beta 1.8.1, Powered Minecarts do not produce the new lighting and glitch nearly always through other carts or get stuck before them.


 * Powered Minecarts the furnace front texture switch to the back and front of the minecart.
