Plans for a levitating train from Las Vegas to Disneyland can move forward under a transportation bill signed by President Bush on Friday that frees up $45 million for the futuristic project.

Derided by critics as pie in the sky, the train would use magnetic levitation technology to carry passengers from Disneyland to Las Vegas in well under two hours, traveling at speeds of up to 300 mph. It would be the first MagLev system in the U.S.

The money is the largest cash infusion in the project's nearly 20-year history. It will pay for environmental studies for the first leg of the project.
