A failure of the main production switcher at CBS owned-and-operated WJZ in Baltimore last night forced the station to partially re-air “CBS Evening News with Scott Pelley” in place of the 11 p.m. newscast.

The station re-aired the national news program, which airs nightly on WJZ at 7 p.m., for the first seven minutes of the 11 p.m. hour Tuesday. “The station’s main production switcher experienced a critical failure late Tuesday evening,” WJZ spokesperson K.C. Robertson told The Baltimore Sun in an email. “The equipment failure prevented the news broadcast from starting on time.”

The problem was repaired shortly before 11:08 p.m., at which point anchors Vic Carter and Denise Koch took over for an abbreviated version of their regular newscast.
