Credit to u/Kahyxen for the "magic" booster(s) used in this - https://www.reddit.com/r/SatisfactoryGame/s/wgROvw0efO

A hypertube launcher that uses boosters that triggers entrances multiple times, shooting you far faster than 12 entrances should.

If you want you can tear down the walls and just keep the tubes, it doesn't change anything.
