Archbishop of Washington Donald W. Wuerl on Tuesday led a prayer service for the staff of the Washington, D.C Metro transit agency following Monday’s crash of a Red Line Metrorail train. Seven died and dozens were injured in the accident.

"Confident that God always remembers the good we have done and God is good and gracious, let us remember those who have died … (and) those who were injured both physically or emotionally," Archbishop Wuerl prayed. "Let us also remember and place before God in prayer the first responders and emergency personnel who came quickly to the aid of the injured and dying. Let us remember the entire Metro family and thank God for their service to this community."

Before the short service, Metro General Manager John Catoe spoke with employees who had gathered outside of Metro headquarters, an Archdiocese of Washington press release says.

Other prayers were offered by Metro employee Carlotta Tyler and Pastor Tony Connelly, a Metro employee and minister at the Greater Lighthouse Church in Lanham, Maryland.

The National Transportation Safety Board is investigating the cause of the crash.
