This is a cross section of the chunnel. We thought it was just a tunnel that you could drive through but Brandon said it was more like a train for the vehicles...and then regular high speed trains. He said the bus pulled onto this tunnel and then he said it just 'shoots' you through it. Brandon said you could look out the windows and see the fish. He was just kidding me, of course.
