If you're talking about a temporary tornado shelter, then yes, it'd work. However, I think there are some additional issues such as access, drainage, moisture, and adequate ventilation that the underground bus fail to address. Let's just pretend there's a twister headed for that trailer park (yes, it IS cliche), and everyone scurries down into the bus. Then said storm arrives and blows a trailer over on top of it....as in on top of the single access door and the two vents. Air circulation is shut off with X number of people in a confined space and they're all yelling for help...how long do you think that's going to last?
I much prefer the designs I saw near at and near a friend's house out near Madison Co. Lake. The area is naturally hilly, so what they did was scoop out a section of a hill, dig in a french drain, and build a cinder block shelter, and re-laid the hill on top and around it. The door is a ship's bulkhead door set into concrete and there's a rabbit hole exit to one side. That takes advantage of natural geography and most importantly doesn't require climbing down a ladder in storm conditions. They basically built a hobbit hole (with emergency exit) before it was popular to do so.
