The Los Angeles Times ( http://lat.ms/12ImwAk) says Nancy Weiford stepped down over the weekend.
An internal report released last Friday called the railroad's accounting system a "morass." It said the agency that serves 40,000 riders daily had underfunded cash accounts by tens of millions of dollars and that its record-keeping was so poor that Metrolink board members couldn't understand it's financial situation.
Weiford declined to comment to the Times.
The report recommends changes that include hiring financial consultants.
