WASHINGTON — The man in charge of safety on Metro submitted his resignation Friday morning, just over a week after the system was shut down for emergency safety inspections.

Acting Chief Safety Officer Lou Brown had been filling the role since former chief safety officer Jim Dougherty resigned in September following a preventable train derailment.

Metro spokesman Dan Stessel says Brown will remain with Metro through late April.

The effort to permanently fill the chief safety officer position has gone through a number of false starts.

Metro has another round of interviews with other candidates for the job scheduled for next week.
