Minecart with Chest

Minecarts with Chests (also called Storage Minecarts) were added to the game in the Seecret Friday Update 7 on July 30 2010. Their main purpose is to function like a minecart while being able to store and transport goods. They work just like normal minecarts, except that they cannot be ridden in.

To use a Minecart with Chest, one must place it on any type of Rail block and right click it. This will bring up an interface the same as a Chest's. Breaking a Storage Minecart will cause everything inside to be dumped out as well as a Minecart and Chest block. Since a Storage Minecart's recipe is only 1x2 spaces, it can be recrafted without a Workbench.

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

Physics
The physical properties of storage minecarts are equal to empty minecarts regardless of the content stored inside them. In other words, they gain the same momentum from boosters and slopes and thus don't travel as far as occupied minecarts after being boosted. This may be a problem as most tracks designed for occupied carts may not have enough boosters for empty carts and storage carts.

Trivia

 * When Minecarts were first implemented, Minecarts with Chests and Minecarts with Furnaces didn't exist. A normal Minecart's purpose was to store things much like the current Storage Minecart.
 * A few updates after Minecarts were added and before Minecarts with Chests and Minecarts with Furnaces were implemented, Minecarts had a strange appearance. They looked exactly like Storage Minecarts that could not store anything, but could still be ridden. When Storage and Powered Minecarts were added, normal Minecarts were given their current appearance.
