Minecart

Minecart can move 20 items at a time, but they cannot harvest items.

Needs a Rail Loader to function.

How to create

 * Open the Build Menu (B)
 * Choose Workers (W)
 * Select Minecart (R)
 * Place the Minecart on a Rail.

Note
The Minecart needs Iron Wheels produced from the Machine Shop and then they must be brought to the Barn or Base.

Minecarts can Load and Unload instantaneously at Minecart Loaders, without needing any other rail cars or train engine.

They can be attached to Train Engines, and will still interact with Minecart Loaders. If the Train stops at a station, its contents will also be loaded or unloaded.

They will struggle to go uphill, so you may need Mechanical Rails or Magic Rails on the uphill sections, or attach a Train Engine to them.

Strategies
The Minecart can be used to quickly pass certain goods between buildings in the right conditions. It can move 20 units per second if placed on a 2x2 rail loop (it can't "pass" goods while standing in place, as a rail stop can't point at different directions at the same time). You can double or triple the amount of carts on the loop, as well as increase the loop size, as longer loops (with maxed amount of carts on it) are less empty, so maximum "passing" efficiency of a rail loop is.
