Flying Rails? Are you kidding me?

Also affects 1.2.0.18,
Yeah, from the beginning of time, first mosquito's flew, then dinosaurs, then birds and so on. And from that evolution, finally, rails could fly too. It's really surprising in an annoying manner.
Steps to reproduce:
1. build a small wall
2. Place rails
3. Destroy that wall,
4. You can even ride that flying rail,
5. How much worse can it get?
6. I can even ride them! Wow!
