Multi-carts strengths lie in their ability to:
1. Potentially travel forever
2. Power themselves without the need of a booster
3. Travel over flat land and water
4. Be created with ease
5. Do minecart jumps! (SUPER ADVANCED TECHNIQUE! Will describe later.)
Multi-carts are not perfect though, and they can be broken apart if the track they are on has too many turns.
Here are the steps to create a multi-cart station
1. Make a rail loop of at least 4 blocks length.
2. Remove one end of the rail loop.
3. Replace the removed rails with solid blocks.
4. Now place a minecart against each rail so that the carts rest against the blocks. The minecarts should move around the bend and combine. You now have a multi-cart!

|...and then the other. The carts should boost each other...|
|...and combine! You now have a multi-cart!|
As the name multi-cart suggests, you can make triple, quadruple, penta, etc carts simply by putting another cart on the empty rail. The more carts you use, the more powerful your cart momentum is, but more carts also means less stability, so your multi-cart becomes even more likely to break apart when turning on a rail.
The multi-cart is not as well researched as boosters, so expect some unexpected things. If a user is unprepared, it is not unusual for them to lose their multicart as it speeds off into the horizon without its rider, but they can be great tools to use while in the wilderness should you need a fast way to travel across a flatland, an ocean or down a mountain.
I am currently testing multi-carts to see what kind of uses they can be put to, so expect further information on the subject at a later time. That includes details on the minecart jumping which I mentioned earlier in the post.
