May I suggest that you read "Maglev America" (available on Amazon) to learn how conversion to URBAN maglev can be accomplished for completion (including switch over) within the existing "budget" of $6.8 billion. It is not designed for high-speed but is designed for superior (and much quieter) performance, with its operating and maintenance costs (including electricity) at about 40 percent of the cost for steel wheels on steel rails. It is 21st Century technology, not a "pig in a poke."
