A virtually endless rollercoaster

Hi again. It's me, Fanawtik, as you might have guessed.

For about the past month, I've been working on a giant adventure map (my subscribers can probably guess what that is) but I decided to take a break and I spent 20 minutes making a rollercoaster that's millions of hundreds of thousands of blocks long. I haven't tested it yet, but it would probably take at least a week to get to the end. Maybe a bit more. That's not sarcasm. If you don't believe me, leave this on over the night and come back in the morning and see if you're still going. :P

And don't try to teleport to the end, either. It won't work.

There's a huge surprise at the end of the coaster. Don't worry, you can go both ways on the track. Both have the same result.
I hope you enjoy this.

If you're playing on a realm or server, make sure command blocks are enabled or you won't be able to summon minecarts at the beginning.

Signing out,
Fanawtik
