The launch tube for the burritos lies just under the tunnel mouth and looks like what it is: an enormous gun. Every four seconds a ‘slug’ of ten burritos, white with frost, ratchets into the breech. A moment later it flies into the tunnel with a loud hiss of compressed gas, and the lights dim briefly as banks of powerful electromagnets accelerate the burritos to over two hundred miles an hour. By the time they pass Stockton three minutes later the burritos will be traveling faster than the Concorde, floating on an invisible magnetic cushion as they plunge into the lithosphere.
Cavanaugh realized that the intense heat of the transit that had so beleaguered mail service would actually work to his advantage in a burrito tunnel. The burritos could be stored frozen on the Western end and arrive fully heated through in New Jersey. Furthermore, advances in electrical engineering meant that containers would no longer have to be propelled by compressed gas. The burritos already came conveniently wrapped in aluminum foil – it would be trivial to accelerate them with powerful magnets.
It’s the attention to physics detail that makes this thing great. Alas, I can’t put it in my “stranger than fiction” category, but I can dream…
