A maglev train inside a semi evacuated (airless) tube allows for maglev trains to travel up to 2000 mph because there is little air resistance. The GM Sequal and hy wire could easily convert tops and get on a new skateboard on the track. And with all that extra space inside the GM cars a turbine could be places in the car top to generate a lot of electricity.
Yeah how do you suck the air out of a tube 500 miles long and 15 feet in circumference, and then maintain that vacuum for long periods?

I wonder how you'd maintain a vacuum that enormous.
