Two of these TBS dug a tunnel under the English Channel to connect France and England and have heard two different names for it: Chunnel tunnel and Euro-tunnel. They have teeth mounted on a large wheel and those teeth eat away at the rock, very similar to the way american rotary snow plows eat away at snow. That rock gets taken out by conveyor belts and then by a temproary railroad. I'm not exactly sure of the wheel dimmentions but it is safe to say, once they get done, American tri-level Auto rack cars would be able to fit through.
