Crazy Hubs
From #openttdcoop wiki
NOTE
These are some of the most unique and memorable hubs we've built. However, you shouldn't take them to heart. They may have been ok at the time, but don't attempt to repeat them, they're not here for that. Instead they're here to show our, er, genius (madness anyone?) to everyone. Again, these are not the normal and appear very rarely, but when hubs like these do evolve, we remember them... They're infamous to say the least.
