The Maryland Transit Administration is adding more quiet cars to its MARC trains to meet the demands of passengers who want to ride in peace without hearing cell-phone chatter or bleating pagers.
The agency announced yesterday that beginning Tuesday all afternoon Penn Line trains that depart Washington between 3:34 p.m. and 7:30 p.m. will have a quiet car. Train 877 on the Brunswick Line and Train 852 on the Camden Line also will have quiet cars.
