Officials increased the cost estimate for the first phase of California's high speed rail project by 35 percent on Tuesday, to $10.6 billion.
That would put the entire cost of the train from San Francisco to Los Angeles at roughly $67 billion, although officials said they hope to recover the newly announced costs later.
"Our first responsibility is to be transparent and forthright," said Dan Richard, chair of the California High Speed Rail Authority's board. "We've got to enhance active management of this program."
The $2.8 billion price jump is for a 119-mile (191-kilometer) segment in the Central Valley, which is partially under construction. The fresh costs are due to trouble acquiring rights of way for the track, the need to build more barriers along the tracks and other items.
