The California High-Speed Rail Authority took a key step toward developing its proposed passenger-train system Thursday, certifying environmental reports and formally approving the first portion of the line between Merced and Fresno.

Skeptics remain even as the authority pushes forward on building as soon as this year. But Thursday, a new booster stepped forward -- Madera real-estate developer Ed McIntyre, who said that he and partners are ready to spend $1 billion developing a maintenance yard and more if the authority puts it on their property in Madera.

McIntyre told the board before its vote that his group believes high-speed rail pencils out as a money-maker. In his group's case, he said, they're certain they can secure financing and recoup their investment through a lease-buy deal with the authority.
