"If it's a maglev type track and there's no friction, why does it matter how fast it goes and/or how strong the track is?"

"The track still must bear the weight of the spacecraft (the magnetic field supports the ship, but what supports the magnetic field!). Also, if the track is curved, the track must be strong enough to hold its shape when Newton's Laws decree that the spacecraft should go in a straight line."

"Look up the Sanger-Brant Concept from world war 2."

"woops I meant the Sanger Silverbird it was meant to take off from a steel and concret rail but add a mag lev and you should get a lot more speed without the problem of friction if you shape the carrier for too take into acount the air friction as well."

"The plane ride would be great! You'll attain escape velocity but only after the ride on the train tracks. The Germans during WW2 came up with something similar, the Silbervogel. The Silbervogel aka Silver Bird was to be a fractional orbital aircraft. Happily for the test pilot it was not built. It would have burnt up on the first try! "
