On Thursday, union construction workers rallied in support of high-speed rail, saying it would mean tens of thousands of jobs.
Meantime, Roelof van Ark, the Rail Authority's chief executive officer, announced his resignation at Thursday's board meeting. The incoming board chairman, Dan Richard, admits there are challenges ahead.
